Data encryption algorithms—Encrypt data to ensure privacy. Commonly used data
encryption algorithms are usually symmetric key algorithms. When using a symmetric key
algorithm, the SSL server and the SSL client must use the same key.
•
Message Authentication Code (MAC) algorithms—Calculate the MAC value for data to
ensure integrity. Commonly used MAC algorithms include MD5 and SHA. When using a MAC
algorithm, the SSL server and the SSL client must use the same key.
•
Key exchange algorithms—Implement secure exchange of the keys used by the symmetric
key algorithm and MAC algorithm. Commonly used key exchange algorithms are asymmetric
key algorithms, such as RSA.
The SSL client sends the preferred cipher suite to the SSL server. The server compares the received
cipher suite with the cipher suits it supports. If a match is found, the cipher suite negotiation
succeeds. If no match is found, the negotiation fails.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Configure SSL client policy policy1 to support the key exchange algorithm RSA, data encryption
algorithm 128-bit AES_CBC, and MAC algorithm SHA.

server-verify enable
Use server-verify enable to enable the SSL client to use digital certificates to authenticate the SSL
server.
Use undo server-verify enable to disable SSL server authentication. The SSL client does not
authenticate the SSL server.
Syntax
server-verify enable
undo server-verify enable
Default
The SSL client uses digital certificates to authenticate the SSL server.
Views
SSL client policy view
Predefined user roles
network-admin
mdc-admin
Usage guidelines
SSL uses digital certificates to authenticate communicating parties. For more information about
digital certificates, see Security Configuration Guide.
If you execute the server-verify enable command, the SSL server must send its digital certificate to
the SSL client for authentication. The client can access the SSL server only after the server passes
the authentication.
