Hi Team,
We are facing below error while connecting to SFTP server
System.Exception: 'Could not negotiate diffie-hellman-group1-sha1.
Could you please share list of key exchange algos supported by SFTP 3.4.6 ?
Hi.
Can you please be more specific what is 'SFTP 3.4.6'? Is it our product and its version? If so, which product exactly, ActiveX or .NET?
Note that we can't provide info about old versions, we can only provide info about latest versions of our products.
Regards,

It's SFTP library we use with version 3.6.4 in C# to connect to SFTP server.
Hi.
Ok, I assume you use wodSFTP.NET in C#.
Did you try latest version? These are suppored in 3.7.3.170:
diffie-hellman-group-exchange-sha256
diffie-hellman-group-exchange-sha1
diffie-hellman-group1-sha1
diffie-hellman-group14-sha1
ecdh-sha2-nistp256
ecdh-sha2-nistp384

We can't update library on our end as multiple teams are using it. Could you please check supporting algos by C# SFTP lib 3.4.6 so that we can try making changes at SFTP server end.
Hi.
As I mentioned, we can't get list for old versions, so I suggest you enable ones that I have listed in previous reply.
I hope this helps!

We can't update library on our end so it used by multiple teams and might break something.
So could you check with your team once regarding supported exchange algos ?
Hi.
No need to upgrade, but please refer to list I provided in previous reply.

I see this list is specific to 3.7.3.170 this version. Please let me know if I'm missing something

Just thought you'd like to know that my gateway app with your SMTP Server component held the line against a DDOS attack today...
