SSL version 2.0 and 3.0 cipher suites supported (in the domestic version)
Figure 14-1
You can choose ciphers from the SSL 2.0 protocol, as well as from SSL 3.0. To
specify which ciphers your server can use, check them in the list of ciphers to
enable them. Unless you have a compelling reason not to use a specific cipher, you
should check them all, except as noted in the warning that follows. For a detailed
description of ciphers, see "Ciphers Used with SSL" in Appendix E of Managing
Servers with Netscape Console.
CAUTION You might not want to check the options that say "No Encryption,
only MD5 message authentication" and "No Encryption, only
Fortezza and SHA message authentication." The reason for this is, if
no other ciphers are available on the client side, the server will use
these and no encryption will occur.
Previous US law prohibited the export of software with strong encryption, so most
browsers still in use outside of the US and Canada do not support 128-bit
encryption. Disabling all 40-bit ciphers will ensure that all connections use
higher-grade security, but will prevent access to your service to many users outside
of the US and Canada.
