Supported SSH Ciphers
Here is a list of SSH ciphers we currently support for use with SFTP:
Key Exchange Algorithms:
- 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
Encryption Algorithms:
- aes128-ctr
- aes192-ctr
- aes256-ctr
MAC Algorithms:
- hmac-sha2-256
- hmac-sha2-512
- hmac-sha1
Compression Algorithms:
- none
NOTE: 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.
On December 15, 2021, we discontinued support for the following insecure key exchange algorithms:
- aes256-gcm
- aes128-gcm
- diffie-hellman-group14-sha1
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
