Supported SSH (and SFTP) Cipher Standards


JAMS V6.5.27 added support for:

Host Key Algorithms ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, and ecdsa-sha2-nistp521. 
Key Exchange Algorithms ecdh-sha2-nistp256, ecdh-sha2-nistp384, and ecdh-sha2-nistp521.

JAMS 6.3 includes support for all ciphers on all hosts, including OpenSSH_4. 

Please note on prior releases. JAMS Supports the following ciphers:

aes256-ctr, aes192-ctr, aes128-ctr, aes256-cbc, aes192-cbc, aes128-cbc, 3des-ctr, 3des-cbc, twofish256-ctr, twofish192-ctr, twofish128-ctr, twofish256-cbc, twofish192-cbc, twofish128-cbc, twofish-cbc, blowfish-ctr, blowfish-cbc, arcfour256, arcfour128, arcfour

If connecting to an OpenSSH_4 host, the following are supported:

aes256-cbc, aes192-cbc, aes128-cbc, 3des-cbc, twofish256-cbc, twofish192-cbc, twofish128-cbc, twofish-cbc, blowfish-cbc, arcfour256, arcfour128, arcfour

The cipher is automatically negotiated between the client and the server; if there is no common match found then a, "no common algorithm" error will occur.
