diffie-hellman group exchange sha256 support (wodSSH / wodSSH.NET)

by david, Monday, March 07, 2016, 20:55 (3183 days ago) @ Jasmine

We have been using the .NET SFTP.NET client for over 10 years. However, we are having trouble connecting to a new client's server that seems to be using diffie-hellman group exchange sha256:

Exception: (Buffer error: start>end)
RemoteIdentification: SSH-2.0-OpenSSH_4.7
SFTP.NET version: still fails with latest 3.4.9.128

We are able to connect using Core FTP app with this handshake:

SH-2.0-OpenSSH_4.7
diffie-hellman-group-exchange-sha256, diffie-hellman-group-exchange-sha1, diffie-hellman-group14-sha1, diffie-hellman-group1-sha1
diffie-hellman-group1-sha1
client -> aes128
server -> aes128
