RSA (Rivest, Shamir, and Adleman) is an algorithm for public key cryptography. It's the first algorithm known to be suitable for signing as well as encryption.
The RSA Keys screen displays a list of RSA keys installed in the selected access point. RSA Keys are generally used for establishing a SSH session, and are a part of the certificate set used by RADIUS, VPN and HTTPS.
To view the controller or service platform's RSA Key details:
The RSA Key Details field describes the size (in bits) of the desired key. If not specified, a default key size of 1024 is used.
The RSA Public Key field describes the public key used for encrypting messages. This key is known to everyone.
