Hi,

We've been using the wodFTPDLX.dll in our .net app for about 10 years now. One of our partners we have an integration with has recently updated their ftp server security to remove older , non secure key exchange algorithms.
When they did this our application lost the ability to connect to their server. We Updated to the latest version of wodFTPDLX in the hopes that it would fix the issue as the version we were on previously was ...ancient to say the least.
Unfortunatly even with the update we still get an error trying to connect to the partners ftp server.
The exception we are getting back states the following.
"Could not negotiate diffie-hellman key exchange."
Our partner was able to provide us with a list of the key exchanges they support.

# Specifies the available KEX (Key Exchange) algorithms.
KexAlgorithms
curve25519-sha256@libssh.org,
diffie-hellman-group18-sha512,
diffie-hellman-group16-sha512,
diffie-hellman-group14-sha256,
diffie-hellman-group-exchange-sha256
# Specifies the ciphers allowed
Ciphers chacha20-poly1305@openssh.com,
aes256-gcm@openssh.com,
aes128-gcm@openssh.com,
aes256-ctr,
aes192-ctr
#Specifies the available MAC (message authentication code) algorithms
MACs hmac-sha2-512-etm@openssh.com,
hmac-sha2-256-etm@openssh.com,
umac-128-etm@openssh.com,
hmac-sha2-512,
hmac-sha2-256

Does wodFTPDLX support any of these? and if so how do we configure that?

Thanks
William D Leonard
