Description

The SSL_CIPHER_LIST option specifies the SSL/TLS cipher suites acceptable for use by the SSL/TLS protocol.

The SSL/TLS protocol uses the cipher suites to specify which encryption and message authentication (or message digest) algorithms to use.

Values

list is a comma-separated list of SSL/TLS cipher suites. The following table identifies the list of SSL/TLS cipher suites supported for this option.

The list is in default order, with the most preferred suite first and the least preferred suite last.

Cipher Suite

Description

AES256-GCM-SHA384

256-bit AES encryption in Galois Counter Mode, SHA-2 384-bit message digest.

AES256-SHA

256-bit AES encryption with SHA-1 message digest.

AES128-GCM-SHA256

128-bit AES encryption in Galois Counter Mode, SHA-2 256-bit message digest.

AES128-SHA

128-bit AES encryption with SHA-1 message digest.

ECDHE-RSA-AES256-GCM-SHA384Ephemeral Elliptic Curve Diffie-Hellman Key Exchange, RSA authentication, 256-bit AES encryption in Galois Counter Mode, SHA-2 384-bit message digest.
ECDHE-ECDSA-AES256-GCM-SHA384Ephemeral Elliptic Curve Diffie-Hellman Key Exchange, ECDSA authentication, 256-bit AES encryption in Galois Counter Mode, SHA-2 384-bit message digest.
ECDHE-RSA-AES128-GCM-SHA256Ephemeral Elliptic Curve Diffie-Hellman Key Exchange, RSA authentication, 128-bit AES encryption in Galois Counter Mode, SHA-2 256-bit message digest.
ECDHE-ECDSA-AES128-GCM-SHA256Ephemeral Elliptic Curve Diffie-Hellman Key Exchange, ECDSA authentication, 128-bit AES encryption in Galois Counter Mode, SHA-2 256-bit message digest.

RC4-SHA

128-bit RC4 encryption with SHA-1 message digest.

Note

As of Universal Agent 7.7.0.0, RC4-SHA is supported only on HP-UX.
 
Additionally, any Agents on HP-UX that accept connections from, or attempt connections to, Agents on other platforms must be configured with at least one currently supported cipher suite besides RC4-SHA. Therefore, those HP-UX Agents cannot be configured only with RC4-SHA in their list of cipher suites.

RC4-MD5

128-bit RC4 encryption with MD5 message digest.

Note

As of Universal Agent 7.7.0.0, RC4-MD5 is supported only on HP-UX.
 
Additionally, any Agents on HP-UX that accept connections from, or attempt connections to, Agents on other platforms must be configured with at least one currently supported cipher suite besides RC4-MD5. Therefore, those HP-UX Agents cannot be configured only with RC4-MD5 in their list of cipher suites.

DES-CBC3-SHA

128-bit Triple-DES encryption with SHA-1 message digest.

DES-CBC-SHA
                                     

128-bit DES encryption with SHA-1 message digest.
 

Note

As of Universal Agent 6.7.0.0, DES-CBC-SHA is supported only on HP-UX.
 
Additionally, any Agents on HP-UX that accept connections from, or attempt connections to, Agents on other platforms must be configured with at least one currently supported cipher suite besides DES-CBC-SHA. Therefore, those HP-UX Agents cannot be configured only with DES-CBC-SHA in their list of cipher suites.
