Key exchange. The key exchange algorithm. DHE stands for Diffie-Hellman; DSS stands for Digital Signature Standard. The 1024 bit ciphers are lower strength ciphers formerly used for export control.

Encryption Algorithm. AES stands for the American Encryption Standard. DES stands for Data Encryption Standard.

Symmetric Key Bit Size. The size in bits of the key used for the actual transport data encryption.

Message Authentication. SHA stands for Secure Hash Algorithm.

NOTE

Directory Server supports ciphers for TLSv1 (recommended) and SSLv3. SSLv2 support is deprecated and not enabled by default in Directory Server.

Directory Server provides the following TLSv1 ciphers:
