  • aes128-cbc—128-bit Advanced Encryption Standard (AES) in CBC mode.
  • aes256-cbc—256-bit AES in CBC mode.
  • aes128-ctr—128-bit AES in CBC mode.
  • aes192-ctr—192-bit AES in counter mode.
  • aes256-ctr—256-bit AES in counter Mode.
  • arcfour128—128-bit RC4-stream cipher in CBC mode.
  • arcfour256—256-bit RC4-stream cipher in CBC mode.
  • blowfish128-cbc—128-bit blowfish-symmetric block cipher in CBC mode.
  • cast128-cbc—128-bit cast in CBC mode.

Note: Ciphers represent a set. To configure ssh ciphers:
