Cipher List Formats

The cipher list you specify for a virtual SSL server consists of one or more cipher strings separated by colons (e.g. RC4:+RSA:+ALL:!NULL:!DH:!EX PORT@STRENGTH). Lists of ciphers can be combined using a logical and operation (+) (e.g. SHA1+DES represents all cipher suites containing the SHA1 and the DES algorithms).

In the colon-separated list, any cipher string can be preceded by the characters !, - or +. These characters serve as modifiers, with the following meanings:

•! permanently deletes the ciphers from the list (e.g. !RSA).

•- deletes the ciphers from the list, but the ciphers can be added again by later options.

•+ moves the ciphers to the end of the list. This option doesn’t add any new ciphers it just moves matching existing ones.

•@STRENGTH is placed at the end of the cipher list, and sorts the list in order of encryption algorithm key length.

The default cipher list used for all virtual SSL servers on the VPN Gateway is ALL@STRENGTH.

A cipher list consisting of the string RC4:ALL:!DH translates into a preferred list of ciphers that begins with all ciphers using RC4 as the encryption algorithm, followed by all cipher suites except the eNULL ciphers (ALL). The final !DH string means that all cipher suites containing the DH (Diffie-Hellman) cipher are removed from the list. (Few of the major web browsers support these ciphers.)
