About algorithms for SSH2

The SSH2 client and server use the following types of algorithms for algorithm negotiation during the Stelnet, SFTP, or SCP session establishment:

• Key exchange algorithms.

• Public key algorithms.

• Encryption algorithms.

• MAC algorithms.

If you specify algorithms, SSH2 uses only the specified algorithms for algorithm negotiation. The client uses the specified algorithms to initiate the negotiation, and the server uses the matching algorithms to negotiate with the client. If multiple algorithms of the same type are specified, the algorithm specified earlier has a higher priority during negotiation.
