FiServ SSCTransmissions for OSi

#1 Post by robrubin » 2018-07-12 15:00

FiServ sent me an e-mail mentioning that as of August 19, 2018 they will be disabling algorithms/cyphers no longer considered secure. I have the list in the e-mail I can forward to the appropriate person at Filezilla.

I can't seem to find any info on this topic on the site so far. Thanks for your direction. I appreciate it.

Rob

What does this have to do with FileZilla?

Thank you botg for your reply. The wording of the rest of the message is below: I am assuming SFTP/SSH client means Filezilla which I use to reach their site today.

"After this point if your SFTP/SSH client does not support the secure algorithms/cyphers you will no longer be able to connect to this server to send and/or receive files.



Please make sure to verify with your SFTP/SSH Software vendor that your current version complies with the following information. Failure to do so may cause you to lose access to the site until you have upgraded your SFTP/SSH client.

Encryption Algorithms To be DISABLED

3des-cbc

aes128-cbc

The remaining ciphers still available on your server are a bit outdated but that's no problem for now, they are still supported by FileZilla.
