Could not negotiate diffie-hellman key exchange - WeOnlyDo Discussion board

Could not negotiate diffie-hellman key exchange (wodSFTP / wodSFTP.NET / wodSFTPdll)

by parthasarathi, Thursday, April 25, 2024, 12:13 (9 days ago)

We are getting the error message "Could not negotiate diffie-hellman key exchange" while sending the file to remote server.
We use WeOnlyDo.Client.SFTP.dll with version 3.4.3.111

Our application uses .NET Framework 4.5.1.
Downloaded the latest version for WeOnlyDo.Client.SFTP.dll with version 3.7.3.170. Found that this dll comes for different .NET versions (2.0 as well as 4.0).

When i was using the WeOnlyDo.Client.SFTP.dll for .NET 4.0, got the below error message " could not be resolved because it was built against the ".NETFramework,Version=v4.8" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.5.1"

So, i was using the WeOnlyDo.Client.SFTP.dll available in .NET 2.0

My question is will the WeOnlyDo.Client.SFTP.dll (3.7.3.170) available in .NET 2.0 support diffie-hellman key exchange algorithm?
