Encryption Algorithms:

  • aes128-ctr
  • aes192-ctr
  • aes256-ctr
  • aes128-gcm
  • aes128-gcm@openssh.com

On September 13, 2020, we discontinued support for the following insecure key exchange algorithms:

  • diffie-hellman-group1-sha1
  • diffie-hellman-group-exchange-sha1
  • diffie-hellman-group-exchange-sha256
