wodSFTP.NET - corrupted mac on input (wodSFTP / wodSFTP.NET / wodSFTPdll)

Dear WOD,

We updated our wodSFTP.dll to the latest version (3.7.0.165) since we are heving more and more client that we cannot connect to. We thought that the reason was 'lack of algorithmes' issues.
But we get the following error now when connecting to those clients: "corrupted mac on input"

Here is our software log:
21/04/2023 11:04:43 | 4 | 1 |Working with wodSFTP.dll version 3.7.0.165
21/04/2023 11:05:44 | 4 | 1 |Attempt 1 of 3 for sending file by SFTP to xxxxxx failed: Corrupted MAC on input.

21/04/2023 11:07:46 | 4 | 1 |Error while sending file by SFTP (xxxxxx): Corrupted MAC on input.

Kind regards,
Jens

Jens,

hi. We need a way to duplicate this. Since connection was made, what is actually travelling over it makes no difference - it could be that after certain amount of data that is being sent this error appears.

But we need to run this in debug mode to tell you more. Can you send us a ticket about this with possible way to duplicate the issue?

Dear Jasmine,

We now are getting "Could not negotiate key exchange algorithm."
It seems that our clients server uses the ssh-ed25519 host key encryption.

Is it possible to provide support for the ssh-ed25519 in the wodSFTP.net?

Kind regards,
Jens

Hi Jens,

yes, we could add it. Please give us few days and it will be in wodSFTP.NET.

Jasmine

Hi.

Can you try now with latest version 3.7.1? We have added support for ssh-ed25519.

Regards,
Jasmine
