* Implement OpenSSH strict key exchange extension * The pseudo-algorithm is only valid in the initial SSH2_MSG_KEXINIT and MUST be ignored if they are present in subsequent SSH2_MSG_KEXINIT packets. * Only send strict kex pseudo algorithm for the first kex. Strictly disable non-kex massages in strict kex mode. * Unit tests for strict kex * More unit tests * More unit tests * Correct file name * Update SessionTest_ConnectingBase.cs * More unit tests * Delete SessionTest_Connecting_ServerSendsMaxIgnoreMessagesBeforeKexInit.cs * Add a comment about throwing exception when inbound sequence number is about to wrap during init kex. * Delete SessionTest_Connecting_ServerSendsDebugMessageAfterKexInit_NoStrictKex.cs * Fix build * Update test/Renci.SshNet.Tests/Classes/SessionTest_Connected.cs --------- Co-authored-by: Rob Hague <rob.hague00@gmail.com>
