+5* Copyright policy
+-_-_-_-_-_-_-_-_-_-_
+
+libssh is a project with distributed copyright ownership, which means we prefer
+the copyright on parts of libssh to be held by individuals rather than
+corporations if possible. There are historical legal reasons for this, but one
+of the best ways to explain it is that it’s much easier to work with
+individuals who have ownership than corporate legal departments if we ever need
+to make reasonable compromises with people using and working with libssh.
+
+We track the ownership of every part of libssh via git, our source code control
+system, so we know the provenance of every piece of code that is committed to
+libssh.
+
+So if possible, if you’re doing libssh changes on behalf of a company who
+normally owns all the work you do please get them to assign personal copyright
+ownership of your changes to you as an individual, that makes things very easy
+for us to work with and avoids bringing corporate legal departments into the
+picture.
+
+If you can’t do this we can still accept patches from you owned by your
+employer under a standard employment contract with corporate copyright
+ownership. It just requires a simple set-up process first.
+
+We use a process very similar to the way things are done in the Linux Kernel
+community, so it should be very easy to get a sign off from your corporate
+legal department. The only changes we’ve made are to accommodate the license we
+use, which is LGPLv2 (or later) whereas the Linux kernel uses GPLv2.
+
+The process is called signing.
+
+How to sign your work
+----------------------
+
+Once you have permission to contribute to libssh from your employer, simply
+email a copy of the following text from your corporate email address to:
+
+contributing@libssh.org
+
+--------------------------------------------------------------------------
+libssh Developer's Certificate of Origin. Version 1.0
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the appropriate
+    version of the GNU General Public License; or
+
+(b) The contribution is based upon previous work that, to the best of
+    my knowledge, is covered under an appropriate open source license
+    and I have the right under that license to submit that work with
+    modifications, whether created in whole or in part by me, under
+    the GNU General Public License, in the appropriate version; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a) or (b) and I have not modified it.
+
+(d) I understand and agree that this project and the contribution are
+    public and that a record of the contribution (including all
+    metadata and personal information I submit with it, including my
+    sign-off) is maintained indefinitely and may be redistributed
+    consistent with the libssh Team's policies and the requirements of
+    the GNU GPL where they are relevant.
+
+(e) I am granting this work to this project under the terms of the
+    GNU Lesser General Public License as published by the
+    Free Software Foundation; either version 2.1 of
+    the License, or (at the option of the project) any later version.
+
+http://www.gnu.org/licenses/lgpl-2.1.html
+--------------------------------------------------------------------------
+
+We will maintain a copy of that email as a record that you have the rights to
+contribute code to libssh under the required licenses whilst working for the
+company where the email came from.
+
+Then when sending in a patch via the normal mechanisms described above, add a
+line that states:
+
+
+   Signed-off-by: Random J Developer <random@developer.example.org>
+
+
+using your real name and the email address you sent the original email you used
+to send the libssh Developer’s Certificate of Origin to us (sorry, no
+pseudonyms or anonymous contributions.)
+
+That’s it! Such code can then quite happily contain changes that have copyright
+messages such as:
+
+
+   (c) Example Corporation.
+
+
+and can be merged into the libssh codebase in the same way as patches from any
+other individual. You don’t need to send in a copy of the libssh Developer’s
+Certificate of Origin for each patch, or inside each patch. Just the sign-off
+message is all that is required once we’ve received the initial email.
 
 Have fun and happy libssh hacking!

-Coding conventions in the libssh tree
-======================================
-
-===========
-Quick Start
-===========
-
-Coding style guidelines are about reducing the number of unnecessary
-reformatting patches and making things easier for developers to work together.
-
-You don't have to like them or even agree with them, but once put in place we
-all have to abide by them (or vote to change them).  However, coding style
-should never outweigh coding itself and so the guidelines described here are
-hopefully easy enough to follow as they are very common and supported by tools
-and editors.
-
-The basic style for C code, is the Linux kernel coding style (See
-Documentation/CodingStyle in the kernel source tree). This closely matches what
-libssh developers use already anyways, with a few exceptions as mentioned
-below.
-
-But to save you the trouble of reading the Linux kernel style guide, here
-are the highlights.
-
-* Maximum Line Width is 80 Characters
-  The reason is not about people with low-res screens but rather sticking
-  to 80 columns prevents you from easily nesting more than one level of
-  if statements or other code blocks.
-
-* Use 4 Spaces to Indent
-
-* No Trailing Whitespace
-  Clean up your files before committing.
-
-* Follow the K&R guidelines.  We won't go through all of them here. Do you
-  have a copy of "The C Programming Language" anyways right?
-
-
-=============
-Editor Hints
-=============
-
-Emacs
-------
-Add the follow to your $HOME/.emacs file:
-
-  (add-hook 'c-mode-hook
-    (lambda ()
-        (c-set-style "linux")
-        (c-toggle-auto-state)))
-
-
-Vim
-----
-
-For the basic vi editor included with all variants of \*nix, add the
-following to $HOME/.vimrc:
-
-    set ts=4 sw=4 et cindent
-
-You can use the Vim gitmodline plugin to store this in the git config:
-
-    http://git.cryptomilk.org/projects/vim-gitmodeline.git/
-
-For Vim, the following settings in $HOME/.vimrc will also deal with
-displaying trailing whitespace:
-
-    if has("syntax") && (&t_Co > 2 || has("gui_running"))
-        syntax on
-        function! ActivateInvisibleCharIndicator()
-            syntax match TrailingSpace "[ \t]\+$" display containedin=ALL
-            highlight TrailingSpace ctermbg=Red
-        endf
-        autocmd BufNewFile,BufRead * call ActivateInvisibleCharIndicator()
-    endif
-    " Show tabs, trailing whitespace, and continued lines visually
-    set list listchars=tab:»·,trail:·,extends:…
-
-    " highlight overly long lines same as TODOs.
-    set textwidth=80
-    autocmd BufNewFile,BufRead *.c,*.h exec 'match Todo /\%>' . &textwidth . 'v.\+/'

-
-==========================
-FAQ & Statement Reference
-==========================
-
-Comments
----------
-
-Comments should always use the standard C syntax.  C++ style comments are not
-currently allowed.
-
-The lines before a comment should be empty. If the comment directly belongs to
-the following code, there should be no empty line after the comment, except if
-the comment contains a summary of multiple following code blocks.
-
-This is good:
-
-    ...
-    int i;
-
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-
-    /* This is a one line comment about i = 5. */
-    i = 5;
-
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /**
-     * @brief This is a doxygen comment.
-     *
-     * This is a more detailed explanation of
-     * this simple function.
-     *
-     * @param[in]   param1     The parameter value of the function.
-     *
-     * @param[out]  result1    The result value of the function.
-     *
-     * @return              0 on success and -1 on error.
-     */
-    int example(int param1, int *result1);
-
-This is bad:
-
-    ...
-    int i;
-    /*
-     * This is a multi line comment,
-     * which explains the logical steps we have to do:
-     *
-     * 1. We need to set i=5, because...
-     * 2. We need to call complex_fn1
-     */
-    /* This is a one line comment about i = 5. */
-    i = 5;
-    /*
-     * This is a multi line comment,
-     * explaining the call to complex_fn1()
-     */
-    ret = complex_fn1();
-    if (ret != 0) {
-    ...
-
-    /*This is a one line comment.*/
-
-    /* This is a multi line comment,
-       with some more words...*/
-
-    /*
-     * This is a multi line comment,
-     * with some more words...*/
-
-Indention & Whitespace & 80 columns
-------------------------------------
-
-To avoid confusion, indentations have to be 4 spaces. Do not use tabs!.  When
-wrapping parameters for function calls, align the parameter list with the first
-parameter on the previous line.  For example,
-
-    var1 = foo(arg1,
-               arg2,
-               arg3);
-
-The previous example is intended to illustrate alignment of function
-parameters across lines and not as encourage for gratuitous line
-splitting.  Never split a line before columns 70 - 79 unless you
-have a really good reason.  Be smart about formatting.
-
-
-If, switch, & Code blocks
---------------------------
-
-Always follow an 'if' keyword with a space but don't include additional
-spaces following or preceding the parentheses in the conditional.
-This is good:
-
-    if (x == 1)
-
-This is bad:
-
-    if ( x == 1 )
-
-or
-
-    if (x==1)
-
-Yes we have a lot of code that uses the second and third form and we are trying
-to clean it up without being overly intrusive.
-
-Note that this is a rule about parentheses following keywords and not
-functions.  Don't insert a space between the name and left parentheses when
-invoking functions.
-
-Braces for code blocks used by for, if, switch, while, do..while, etc.  should
-begin on the same line as the statement keyword and end on a line of their own.
-You should always include braces, even if the block only contains one
-statement.  NOTE: Functions are different and the beginning left brace should
-be located in the first column on the next line.
-
-If the beginning statement has to be broken across lines due to length, the
-beginning brace should be on a line of its own.
-
-The exception to the ending rule is when the closing brace is followed by
-another language keyword such as else or the closing while in a do..while loop.
-
-Good examples:
-
-    if (x == 1) {
-        printf("good\n");
-    }
-
-    for (x = 1; x < 10; x++) {
-        print("%d\n", x);
-    }
-
-    for (really_really_really_really_long_var_name = 0;
-         really_really_really_really_long_var_name < 10;
-         really_really_really_really_long_var_name++)
-    {
-        print("%d\n", really_really_really_really_long_var_name);
-    }
-
-    do {
-        printf("also good\n");
-    } while (1);
-
-Bad examples:
-
-    while (1)
-    {
-        print("I'm in a loop!\n"); }
-
-    for (x=1;
-         x<10;
-         x++)
-    {
-        print("no good\n");
-    }
-
-    if (i < 10)
-        print("I should be in braces.\n");
-
-
-Goto
------
-
-While many people have been academically taught that "goto"s are fundamentally
-evil, they can greatly enhance readability and reduce memory leaks when used as
-the single exit point from a function. But in no libssh world what so ever is a
-goto outside of a function or block of code a good idea.
-
-Good Examples:
-
-    int function foo(int y)
-    {
-        int *z = NULL;
-        int rc = 0;
-
-        if (y < 10) {
-            z = malloc(sizeof(int)*y);
-            if (z == NULL) {
-                rc = 1;
-                goto done;
-            }
-        }
-
-        print("Allocated %d elements.\n", y);
-
-    done:
-        if (z != NULL) {
-            free(z);
-        }
-
-        return rc;
-    }
-
-
-Typedefs
----------
-
-libssh tries to avoid "typedef struct { .. } x_t;" so we do always try to use
-"struct x { .. };". We know there are still such typedefs in the code, but for
-new code, please don't do that anymore.
-
-Make use of helper variables
------------------------------
-
-Please try to avoid passing function calls as function parameters in new code.
-This makes the code much easier to read and it's also easier to use the "step"
-command within gdb.
-
-Good Example:
-
-    char *name;
-
-    name = get_some_name();
-    if (name == NULL) {
-        ...
-    }
-
-    rc = some_function_my_name(name);
-    ...
-
-
-Bad Example:
-
-    rc = some_function_my_name(get_some_name());
-    ...
-
-Please try to avoid passing function return values to if- or while-conditions.
-The reason for this is better handling of code under a debugger.
-
-Good example:
-
-    x = malloc(sizeof(short) * 10);
-    if (x == NULL) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-Bad example:
-
-    if ((x = malloc(sizeof(short)*10)) == NULL ) {
-        fprintf(stderr, "Unable to alloc memory!\n");
-    }
-
-There are exceptions to this rule. One example is walking a data structure in
-an iterator style:
-
-    while ((opt = poptGetNextOpt(pc)) != -1) {
-        ... do something with opt ...
-    }
-
-But in general, please try to avoid this pattern.
-
-
-Control-Flow changing macros
------------------------------
-
-Macros like STATUS_NOT_OK_RETURN that change control flow (return/goto/etc)
-from within the macro are considered bad, because they look like function calls
-that never change control flow. Please do not introduce them.

-How to contribute a patch to libssh
-====================================
-
-Simple, just make the code change, and email it as either a "diff -u"
-change, or as a "git format-patch" change against the original source
-code to libssh@libssh.org, or attach it to a bug report at
-https://red.libssh.org/
-
-For larger code changes, breaking the changes up into a set of simple
-patches, each of which does a single thing, are much easier to review.
-Patch sets like that will most likely have an easier time being merged
-into the libssh code than large single patches that make lots of
-changes in one large diff.
-
-Ownership of the contributed code
-==================================
-
-libssh is a project with distributed copyright ownership, which means
-we prefer the copyright on parts of libssh to be held by individuals

-We use a process very similar to the way things are done in the Linux
-Kernel community, so it should be very easy to get a sign off from
-your corporate legal department. The only changes we've made are to
-accommodate the license we use, which is LGPLv2 (or later) whereas the
-Linux kernel uses GPLv2.
-
-The process is called signing.
-
-How to sign your work
-----------------------
-
-Once you have permission to contribute to libssh from your employer, simply
-email a copy of the following text from your corporate email address to:
-
-contributing@libssh.org
-
-
-
-libssh Developer's Certificate of Origin. Version 1.0
-
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the appropriate
-    version of the GNU General Public License; or
-
-(b) The contribution is based upon previous work that, to the best of
-    my knowledge, is covered under an appropriate open source license
-    and I have the right under that license to submit that work with
-    modifications, whether created in whole or in part by me, under
-    the GNU General Public License, in the appropriate version; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a) or (b) and I have not modified it.
-
-(d) I understand and agree that this project and the contribution are
-    public and that a record of the contribution (including all
-    metadata and personal information I submit with it, including my
-    sign-off) is maintained indefinitely and may be redistributed
-    consistent with the libssh Team's policies and the requirements of
-    the GNU GPL where they are relevant.
-
-(e) I am granting this work to this project under the terms of the
-    GNU Lesser General Public License as published by the
-    Free Software Foundation; either version 2.1 of
-    the License, or (at the option of the project) any later version.
-
-    http://www.gnu.org/licenses/lgpl-2.1.html
-
-
-We will maintain a copy of that email as a record that you have the
-rights to contribute code to libssh under the required licenses whilst
-working for the company where the email came from.
-
-Then when sending in a patch via the normal mechanisms described
-above, add a line that states:
-
-   Signed-off-by: Random J Developer <random@developer.example.org>
-
-using your real name and the email address you sent the original email
-you used to send the libssh Developer's Certificate of Origin to us
-(sorry, no pseudonyms or anonymous contributions.)
-
-That's it! Such code can then quite happily contain changes that have
-copyright messages such as:
-
-   (c) Example Corporation.
-
-and can be merged into the libssh codebase in the same way as patches
-from any other individual. You don't need to send in a copy of the
-libssh Developer's Certificate of Origin for each patch, or inside each
-patch. Just the sign-off message is all that is required once we've
-received the initial email.
-
-Have fun and happy libssh hacking !
-
-The libssh Team

-1. Introduction
-
-This document describes the key exchange methode curve25519-sha256@libssh.org
-for SSH version 2 protocol. It is provided as an alternative to the existing
-key exchange mechanisms based on either Diffie-Hellman or Elliptic Curve Diffie-
-Hellman [RFC5656].
-The reason is the following : During summer of 2013, revelations from ex-
-consultant at NSA Edward Snowden gave proof that NSA willingly inserts backdoors
-into softwares, hardware components and published standards. While it is still
-believed that the mathematics behind ECC cryptography are still sound and solid,
-some people (including Bruce Schneier [SCHNEIER]), showed their lack of confidence
-in NIST-published curves such as nistp256, nistp384, nistp521, for which constant
-parameters (including the generator point) are defined without explanation. It
-is also believed that NSA had a word to say in their definition. These curves
-are not the most secure or fastest possible for their key sizes [DJB], and
-researchers think it is possible that NSA have ways of cracking NIST curves.
-It is also interesting to note that SSH belongs to the list of protocols the NSA
-claims to be able to eavesdrop. Having a secure replacement would make passive
-attacks much harder if such a backdoor exists.
-
-However an alternative exists in the form of Curve25519. This algorithm has been
-proposed in 2006 by DJB [Curve25519]. Its main strengths are its speed, its
-constant-time run time (and resistance against side-channel attacks), and its
-lack of nebulous hard-coded constants.
-
-The reference version being used in this document is the one described in
-[Curve25519] as implemented in the library NaCl [NaCl].
-This document does not attempt to provide alternatives to the ecdsa-sha1-*
-authentication keys.
-
-2. Key exchange
-
-The key exchange procedure is very similar to the one described chapter 4 of
-[RFC5656]. Public ephemeral keys are transmitted over SSH encapsulated into
-standard SSH strings.
-
-The following is an overview of the key exchange process:
-
-Client                                                            Server
-------                                                            ------
-Generate ephemeral key pair.
-SSH_MSG_KEX_ECDH_INIT          -------->                      
-                                            Verify that client public key 
-                                            length is 32 bytes.
-                                             Generate ephemeral key pair.
-                                                   Compute shared secret.
-                                         Generate and sign exchange hash.
-                               <--------           SSH_MSG_KEX_ECDH_REPLY
-Verify that server public key length is 32 bytes.
-* Verify host keys belong to server.
-Compute shared secret.
-Generate exchange hash.
-Verify server's signature.
-
-*   Optional but strongly recommanded as this protects against MITM attacks.
-
-This is implemented using the same messages as described in RFC5656 chapter 4
-
-3. Method Name
-
-The name of this key exchange method is "curve25519-sha256@libssh.org".
-
-4. Implementation considerations
-
-The whole method is based on the curve25519 scalar multiplication. In this
-method, a private key is a scalar of 256 bits, and a public key is a point
-of 256 bits.
-
-4.1. Private key generation
-
-A 32 bytes private key should be generated for each new connection,
- using a secure PRNG. The following actions must be done on the private key:
-     mysecret[0] &= 248;
-     mysecret[31] &= 127;
-     mysecret[31] |= 64;
-In order to keep the key valid. However, many cryptographic libraries will do
-this automatically.
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the result is a valid and secure private key.
-
-4.2 Public key generation
-
-The 32 bytes public key of either a client or a server must be generated using
-the 32 bytes private key and a common generator base. This base is defined as 9
-followed by all zeroes:
-     const unsigned char basepoint[32] = {9};
-
-The public key is calculated using the cryptographic scalar multiplication:
-     const unsigned char privkey[32];
-     unsigned char pubkey[32];
-     crypto_scalarmult (pubkey, privkey, basepoint);
-However some cryptographic libraries may provide a combined function:
-     crypto_scalarmult_base (pubkey, privkey);
-
-It should be noted that, in opposition to NIST curves, no special validation
-should be done to ensure the received public keys are valid curves point. The
-Curve25519 algorithm ensure that every possible public key maps to a valid
-ECC Point.
-
-4.3 Shared secret generation
-
-The shared secret, k, is defined in SSH specifications to be a big integer.
-This number is calculated using the following procedure:
-
-     X is the 32 bytes point obtained by the scalar multiplication of the other
-     side's public key and the local private key scalar.
-
-     The whole 32 bytes of the number X are then converted into a big integer k.
-     This conversion follows the network byte order. This step differs from 
-     RFC5656.

-message and error code from the ssh_session using ssh_get_error() and
