Minimum RSA Key Size
The minimum allowed size of the RSA key. The minimum value is 512 bits, with a default value of 1024 bits.
Determines whether to validate the fingerprints of remote servers. This can increase security by verifying the identity of the servers being connected to before credentials are sent to the server. This can help to prevent a man in the middle attack.
Allow legacy key exchange algorithms
Determines whether the connection should allow for less secure legacy key exchange algorithms.
