If it is not included +then the default cipher list will be used. The format is described below. + +=back + +=head1 CIPHER LIST FORMAT + +The cipher list consists of one or more I<cipher strings> separated by colons. +Commas or spaces are also acceptable separators but colons are normally used. + +The actual cipher string can take several different forms. + +It can consist of a single cipher suite such as B<RC4-SHA>. + +It can represent a list of cipher suites containing a certain algorithm, or +cipher suites of a certain type. For example B<SHA1> represents all ciphers +suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 +algorithms. + +Lists of cipher suites can be combined in a single cipher string using the +B<+> character. This is used as a logical B<and> operation. For example +B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES +algorithms. + +Each cipher string can be optionally preceded by the characters B<!>, +B<-> or B<+>. + +If B<!> is used then the ciphers are permanently deleted from the list. +The ciphers deleted can never reappear in the list even if they are +explicitly stated. + +If B<-> is used then the ciphers are deleted from the list, but some or +all of the ciphers can be added again by later options. + +If B<+> is used then the ciphers are moved to the end of the list. This +option doesn't add any new ciphers it just moves matching existing ones. + +If none of these characters is present then the string is just interpreted +as a list of ciphers to be appended to the current preference list. If the +list includes any ciphers already present they will be ignored: that is they +will not moved to the end of the list. + +The cipher string B<@STRENGTH> can be used at any point to sort the current +cipher list in order of encryption algorithm key length. + +The cipher string B<@SECLEVEL=n> can be used at any point to set the security +level to B<n>. + +=head1 CIPHER STRINGS + +The following is a list of all permitted cipher strings and their meanings. + +=over 4 + +=item B<DEFAULT> + +The default cipher list. +This is determined at compile time and is normally +B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. +When used, this must be the first cipherstring specified. + +=item B<COMPLEMENTOFDEFAULT> + +The ciphers included in B<ALL>, but not enabled by default. Currently +this includes all RC4 and anonymous ciphers. Note that this rule does +not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if +necessary). Note that RC4 based ciphersuites are not built into OpenSSL by +default (see the enable-weak-ssl-ciphers option to Configure). + +=item B<ALL> + +All cipher suites except the B<eNULL> ciphers (which must be explicitly enabled +if needed). +As of OpenSSL 1.0.0, the B<ALL> cipher suites are sensibly ordered by default. + +=item B<COMPLEMENTOFALL> + +The cipher suites not enabled by B<ALL>, currently B<eNULL>. + +=item B<HIGH> + +"high" encryption cipher suites. This currently means those with key lengths +larger than 128 bits, and some cipher suites with 128-bit keys. + +=item B<MEDIUM> + +"medium" encryption cipher suites, currently some of those using 128 bit +encryption. + +=item B<LOW> + +"low" encryption cipher suites, currently those using 64 or 56 bit +encryption algorithms but excluding export cipher suites. All these +ciphersuites have been removed as of OpenSSL 1.1.0. + +=item B<eNULL>, B<NULL> + +The "NULL" ciphers that is those offering no encryption. Because these offer no +encryption at all and are a security risk they are not enabled via either the +B<DEFAULT> or B<ALL> cipher strings. +Be careful when building cipherlists out of lower-level primitives such as +B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers. When in +doubt, include B<!eNULL> in your cipherlist. + +=item B<aNULL> + +The cipher suites offering no authentication. This is currently the anonymous +DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable +to "man in the middle" attacks and so their use is discouraged. +These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL> +ciphers. +Be careful when building cipherlists out of lower-level primitives such as +B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers. +When in doubt, include B<!aNULL> in your cipherlist. + +=item B<kRSA>, B<aRSA>, B<RSA> + +Cipher suites using RSA key exchange or authentication.

all ciphers except ones with no encryption (eNULL) or no +authentication (aNULL): + + openssl ciphers -v 'ALL:!aNULL' + +Include only 3DES ciphers and then place RSA ciphers last: + + openssl ciphers -v '3DES:+RSA' + +Include all RC4 ciphers but leave out those without authentication: + + openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT' + +Include all ciphers with RSA authentication but leave out ciphers without +encryption. + + openssl ciphers -v 'RSA:!COMPLEMENTOFALL' + +Set security level to 2 and display all ciphers consistent with level 2: + + openssl ciphers -s -v 'ALL:@SECLEVEL=2' +
