6 openssl-ciphers - SSL cipher display and cipher list command
30 This command converts textual OpenSSL cipher lists into
31 ordered SSL cipher preference lists. It can be used to
47 minimum and maximum protocol version.  This is closer to the actual cipher list

112 =head1 CIPHER LIST FORMAT
114 The cipher list consists of one or more I<cipher strings> separated by colons.
117 The cipher string may reference a cipher using its standard name from
118 the IANA TLS Cipher Suites Registry
121 The actual cipher string can take several different forms.
123 It can consist of a single cipher suite such as B<RC4-SHA>.
125 It can represent a list of cipher suites containing a certain algorithm, or
126 cipher suites of a certain type. For example B<SHA1> represents all ciphers
130 Lists of cipher suites can be combined in a single cipher string using the
132 B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
135 Each cipher string can be optionally preceded by the characters B<!>,
153 The cipher string B<@STRENGTH> can be used at any point to sort the current
154 cipher list in order of encryption algorithm key length.
156 The cipher string B<@SECLEVEL>=I<n> can be used at any point to set the security
160 The cipher list can be prefixed with the B<DEFAULT> keyword, which enables
161 the default cipher list as defined below.  Unlike cipher strings,
