This parameter specifies the default shared secret to be used
to decrypt Tacacs+ messages. When a new connection from a Tacacs+ client
is received, ServerTACACSPLUS tries to find a Key to use for decrypting
that connection. EncryptedKey is in encrypted format and is preferred over
Key. For more information, see
Section 3.119.1. Key.
EncryptedKey
is currently experimental and will be fully documented
later.
