It can be used as a test tool to determine 2159191Skristhe appropriate cipherlist. 2259191Skris 2359191Skris=head1 COMMAND OPTIONS 2459191Skris 2559191Skris=over 4 2659191Skris 2759191Skris=item B<-v> 2859191Skris 29238405SjkimVerbose option.

If it is not included 6059191Skristhen the default cipher list will be used. The format is described below. 6159191Skris 6259191Skris=back 6359191Skris 6459191Skris=head1 CIPHER LIST FORMAT 6559191Skris 6659191SkrisThe cipher list consists of one or more I<cipher strings> separated by colons. 6759191SkrisCommas or spaces are also acceptable separators but colons are normally used. 6859191Skris 6959191SkrisThe actual cipher string can take several different forms. 7059191Skris 7159191SkrisIt can consist of a single cipher suite such as B<RC4-SHA>. 7259191Skris 7359191SkrisIt can represent a list of cipher suites containing a certain algorithm, or 7459191Skriscipher suites of a certain type. For example B<SHA1> represents all ciphers 7559191Skrissuites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 7659191Skrisalgorithms. 7759191Skris 7859191SkrisLists of cipher suites can be combined in a single cipher string using the 7959191SkrisB<+> character. This is used as a logical B<and> operation. For example 8059191SkrisB<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES 8159191Skrisalgorithms. 8259191Skris 8359191SkrisEach cipher string can be optionally preceded by the characters B<!>, 8459191SkrisB<-> or B<+>. 8559191Skris 8659191SkrisIf B<!> is used then the ciphers are permanently deleted from the list. 8759191SkrisThe ciphers deleted can never reappear in the list even if they are 8859191Skrisexplicitly stated. 8959191Skris 9059191SkrisIf B<-> is used then the ciphers are deleted from the list, but some or 9159191Skrisall of the ciphers can be added again by later options. 9259191Skris 9359191SkrisIf B<+> is used then the ciphers are moved to the end of the list. This 9459191Skrisoption doesn't add any new ciphers it just moves matching existing ones. 9559191Skris 9659191SkrisIf none of these characters is present then the string is just interpreted 9759191Skrisas a list of ciphers to be appended to the current preference list. If the 9859191Skrislist includes any ciphers already present they will be ignored: that is they 9959191Skriswill not moved to the end of the list. 10059191Skris 10159191SkrisAdditionally the cipher string B<@STRENGTH> can be used at any point to sort 10259191Skristhe current cipher list in order of encryption algorithm key length. 10359191Skris 10459191Skris=head1 CIPHER STRINGS 10559191Skris 10659191SkrisThe following is a list of all permitted cipher strings and their meanings. 10759191Skris 10859191Skris=over 4 10959191Skris 11059191Skris=item B<DEFAULT> 11159191Skris 112280304Sjkimthe default cipher list.
