Does jsch support AES256-SDCTR?

Open avnerw74 opened this issue 1 year ago • 2 comments

Hi,

We have a customer that changed their SFTP server cipher to AES256-SDCTR. They are getting error: "Algorithm negotiation fail".

Is AES256-SDCTR supported by JSCH? If yes, which cipher should be mentioned in the ciphers list? (aes256-ctr)? If no, are there any plans to support it?

Regards, Avner

Hi @avnerw74,

Did you actually try to enable aes256-ctr and it failed? Also, have you enabled logging in JSch to see better why the connection failed?

Thanks, Jeremy

Hi @norrisjeremy,

Thanks for the reply. Logging wasn't yet enabled. I'll ask them to test aes256-ctr (though I believe it was in the ciphers list, as it is enabled by default).

Thanks, Avner
