RSA and DSA. RSA and DSA are two of the encryption algorithms that can be used to generate keys. WS_FTP Server supports both types of keys.
Host key. The host key is the key that the server presents to the client to prove its identity.
User key. The user key is the key that the client presents to the server to prove its identity.
MAC. Message Authentication Code is a secret code agreed upon by the client and the server during SSH negotiations. The MAC is used to verify the integrity of packets sent between the two.
Cipher. Ciphers are cryptographic algorithms used to encrypt SSH connections.
