The default rekeying recommendations are specified in RFC4344 Section 3 (First and Second Rekeying Recommendations). Additionally, the rekeying can be specified in configuration file/options allowing us to turn the rekeying off, base it on time or make it more strict. The code is highly inspired by the OpenSSH rekeying code. Signed-off-by: Jakub Jelen <jjelen@redhat.com> Reviewed-by: Daiki Ueno <dueno@redhat.com> Reviewed-by: Andreas Schneider <asn@cryptomilk.org>
