-# How to contribute a patch to libssh
+Coding conventions in the libssh tree
+======================================
 
-Please checkout the libssh source code using git.
-
-For contributions we prefer Merge Requests on Gitlab:
-
-https://gitlab.com/libssh/libssh-mirror/
-
-This way you get continuous integration which runs the complete libssh
-testsuite for you.
-
-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.
-
-Also bugfixes and new features should be covered by tests. We use the cmocka
-and cwrap framework for our testing and you can simply run it locally by
-calling `make test`.
-
-## 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
-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 https://git.libssh.org,
-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.
-
-    https://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.

+How to contribute a patch to libssh
+====================================
+
+Please checkout the libssh source code using git. Change the code and then
+use  "git format-patch" to create a patch. The patch should be signed (see
+below) and send it to libssh@libssh.org, or attach it to a bug report at

-/**
-@page libssh_tutor_pkcs11 Chapter 9: Authentication using PKCS #11 URIs
-@section how_to How to use PKCS #11 URIs in libssh?
-
-PKCS #11 is a Cryptographic Token Interface Standard that provides an API
-to devices like smart cards that store cryptographic private information.
-Such cryptographic devices are referenced as tokens. A mechanism through which
-objects stored on the tokens can be uniquely identified is called PKCS #11 URI
-(Uniform Resource Identifier) and is defined in RFC 7512
-(https://tools.ietf.org/html/rfc7512).
-
-Pre-requisites:
-
-OpenSSL defines an abstract layer called the "engine" to achieve cryptographic
-acceleration. The engine_pkcs11 module acts like an interface between the PKCS #11
-modules and the OpenSSL engine.
-
-To build and use libssh with PKCS #11 support:
-1. Enable the cmake option: $ cmake -DWITH_PKCS11_URI=ON
-2. Build with OpenSSL.
-3. Install and configure engine_pkcs11 (https://github.com/OpenSC/libp11).
-4. Plug in a working smart card or configure softhsm (https://www.opendnssec.org/softhsm).
-
-The functions  ssh_pki_import_pubkey_file() and ssh_pki_import_privkey_file() that
-import the public and private keys from files respectively are now modified to support
-PKCS #11 URIs. These functions automatically detect if the provided filename is a file path
-or a PKCS #11 URI (when it begins with "pkcs11:"). If a PKCS #11 URI is detected,
-the engine is loaded and initialized. Through the engine, the private/public key
-corresponding to the PKCS #11 URI are loaded from the PKCS #11 device.
-
-If you wish to authenticate using public keys on your own, follow the steps mentioned under
-"Authentication with public keys" in Chapter 2 - A deeper insight into authentication.
-
-The function pki_uri_import() is used to populate the public/private ssh_key from the 
-engine with PKCS #11 URIs as the look up.
-
-Here is a minimalistic example of public key authentication using PKCS #11 URIs:
-
-@code
-int authenticate_pkcs11_URI(ssh_session session)
-{
-  int rc;
-  char priv_uri[1042] = "pkcs11:token=my-token;object=my-object;type=private?pin-value=1234";
-
-  rc = ssh_options_set(session, SSH_OPTIONS_IDENTITY, priv_uri);
-  assert_int_equal(rc, SSH_OK)
-
-  rc = ssh_userauth_publickey_auto(session, NULL, NULL);
-
-  if (rc == SSH_AUTH_ERROR)
-  {
-     fprintf(stderr, "Authentication with PKCS #11 URIs failed: %s\n",
-       ssh_get_error(session));
-     return SSH_AUTH_ERROR;
-  }
-
-  return rc;
-}
-@endcode
-
-@subsection Caveats
-
-We recommend the users to provide a specific PKCS #11 URI so that it matches only a single slot in the engine.
-If the engine discovers multiple slots that could potentially contain the private keys referenced
-by the provided PKCS #11 URI, the engine will not try to authenticate.

- * ==============
- *
- * AUTHOR URL
- * https://gitlab.com/marco.fortina/libssh-x11-client/
- *
- * This is a simple example of SSH X11 client using libssh.
- *
- * Features:
- *
- * - support local display (e.g. :0)
- * - support remote display (e.g. localhost:10.0)
- * - using callbacks and event polling to significantly reduce CPU utilization
- * - use X11 forwarding with authentication spoofing (like openssh)
- *
- * Note:
- *
- * - part of this code was inspired by openssh's one.
- *
- * Dependencies:
- *
- * - gcc >= 7.5.0
- * - libssh >= 0.8.0
- * - libssh-dev >= 0.8.0
- *
- * To Build:
- * gcc -o ssh_X11_client ssh_X11_client.c -lssh -g
