Supported SSH Ciphers

Here is a list of SSH ciphers we currently support for use with SFTP.

Key Exchange Algorithms

  • curve25519-sha256@libssh.org

  • curve25519-sha256

  • ecdh-sha2-nistp256

  • ecdh-sha2-nistp384

  • ecdh-sha2-nistp521

  • diffie-hellman-group14-sha256

  • diffie-hellman-group15-sha512

  • diffie-hellman-group16-sha512

  • diffie-hellman-group17-sha512

  • diffie-hellman-group18-sha512

Host Key Algorithms

  • ssh-rsa

  • rsa-sha2-512

  • rsa-sha2-256

Encryption Algorithms

  • aes128-gcm@openssh.com

  • aes256-gcm@openssh.com

  • aes128-ctr

  • aes192-ctr

  • aes256-ctr

MAC Algorithms

  • hmac-sha2-256-etm@openssh.com

  • hmac-sha2-512-etm@openssh.com

  • hmac-sha1-etm@openssh.com

  • hmac-sha2-256

  • hmac-sha2-512

  • hmac-sha1

Compression Algorithms

  • none

The host key length is 4096 bits which may be too large for some older FTP clients. Ensure that you are using a version of your SFTP client (or client library) that the vendor supports.
