It can be used as a test tool to determine 32the appropriate cipherlist. 33 34=head1 OPTIONS 35 36=over 4 37 38=item B<-help> 39 40Print a usage message. 41 42=item B<-s> 43 44Only list supported ciphers: those consistent with the security level, and 45minimum and maximum protocol version. This is closer to the actual cipher list 46an application will support. 47 48PSK and SRP ciphers are not enabled by default: they require B<-psk> or B<-srp> 49to enable them. 50 51It also does not change the default list of supported signature algorithms. 52 53On a server the list of supported ciphers might also exclude other ciphers 54depending on the configured certificates and presence of DH parameters. 55 56If this option is not used then all ciphers that match the cipherlist will be 57listed. 58 59=item B<-psk> 60 61When combined with B<-s> includes cipher suites which require PSK. 62 63=item B<-srp> 64 65When combined with B<-s> includes cipher suites which require SRP. 66 67=item B<-v> 68 69Verbose output: For each cipher suite, list details as provided by 70L<SSL_CIPHER_description(3)>. 71 72=item B<-V> 73 74Like B<-v>, but include the official cipher suite values in hex. 75 76=item B<-tls1_3>, B<-tls1_2>, B<-tls1_1>, B<-tls1>, B<-ssl3> 77 78In combination with the B<-s> option, list the ciphers which could be used if 79the specified protocol were negotiated. 80Note that not all protocols and flags may be available, depending on how 81OpenSSL was built. 82 83=item B<-stdname> 84 85Precede each cipher suite by its standard name. 86 87=item B<-convert name> 88 89Convert a standard cipher B<name> to its OpenSSL name. 90 91=item B<-ciphersuites val> 92 93Sets the list of TLSv1.3 ciphersuites. This list will be combined with any 94TLSv1.2 and below ciphersuites that have been configured. The format for this 95list is a simple colon (":") separated list of TLSv1.3 ciphersuite names. By 96default this value is: 97 98 TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256 99 100=item B<cipherlist> 101 102A cipher list of TLSv1.2 and below ciphersuites to convert to a cipher 103preference list. This list will be combined with any TLSv1.3 ciphersuites that 104have been configured. If it is not included then the default cipher list will be 105used. The format is described below. 106 107=back 108 109=head1 CIPHER LIST FORMAT 110 111The cipher list consists of one or more I<cipher strings> separated by colons. 112Commas or spaces are also acceptable separators but colons are normally used. 113 114The actual cipher string can take several different forms. 115 116It can consist of a single cipher suite such as B<RC4-SHA>. 117 118It can represent a list of cipher suites containing a certain algorithm, or 119cipher suites of a certain type. For example B<SHA1> represents all ciphers 120suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 121algorithms. 122 123Lists of cipher suites can be combined in a single cipher string using the 124B<+> character. This is used as a logical B<and> operation. For example 125B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES 126algorithms. 127 128Each cipher string can be optionally preceded by the characters B<!>, 129B<-> or B<+>. 130 131If B<!> is used then the ciphers are permanently deleted from the list. 132The ciphers deleted can never reappear in the list even if they are 133explicitly stated. 134 135If B<-> is used then the ciphers are deleted from the list, but some or 136all of the ciphers can be added again by later options. 137 138If B<+> is used then the ciphers are moved to the end of the list. This 139option doesn't add any new ciphers it just moves matching existing ones. 140 141If none of these characters is present then the string is just interpreted 142as a list of ciphers to be appended to the current preference list. If the 143list includes any ciphers already present they will be ignored: that is they 144will not moved to the end of the list. 145 146The cipher string B<@STRENGTH> can be used at any point to sort the current 147cipher list in order of encryption algorithm key length. 148 149The cipher string B<@SECLEVEL=n> can be used at any point to set the security 150level to B<n>, which should be a number between zero and five, inclusive. 151See L<SSL_CTX_set_security_level> for a description of what each level means. 152 153The cipher list can be prefixed with the B<DEFAULT> keyword, which enables 154the default cipher list as defined below. Unlike cipher strings, 155this prefix may not be combined with other strings using B<+> character. 156For example, B<DEFAULT+DES> is not valid. 157 158The content of the default list is determined at compile time and normally 159corresponds to B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. 160 161=head1 CIPHER STRINGS 162 163The following is a list of all permitted cipher strings and their meanings. 164 165=over 4 166 167=item B<COMPLEMENTOFDEFAULT> 168 169The ciphers included in B<ALL>, but not enabled by default. Currently 170this includes all RC4 and anonymous ciphers. Note that this rule does 171not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if 172necessary). Note that RC4 based cipher suites are not built into OpenSSL by 173default (see the enable-weak-ssl-ciphers option to Configure). 174 175=item B<ALL> 176 177All cipher suites except the B<eNULL> ciphers (which must be explicitly enabled 178if needed). 179As of OpenSSL 1.0.0, the B<ALL> cipher suites are sensibly ordered by default. 180 181=item B<COMPLEMENTOFALL> 182 183The cipher suites not enabled by B<ALL>, currently B<eNULL>. 184 185=item B<HIGH> 186 187"High" encryption cipher suites. This currently means those with key lengths 188larger than 128 bits, and some cipher suites with 128-bit keys. 189 190=item B<MEDIUM> 191 192"Medium" encryption cipher suites, currently some of those using 128 bit 193encryption. 194 195=item B<LOW> 196 197"Low" encryption cipher suites, currently those using 64 or 56 bit 198encryption algorithms but excluding export cipher suites. All these 199cipher suites have been removed as of OpenSSL 1.1.0. 200 201=item B<eNULL>, B<NULL> 202 203The "NULL" ciphers that is those offering no encryption. Because these offer no 204encryption at all and are a security risk they are not enabled via either the 205B<DEFAULT> or B<ALL> cipher strings. 206Be careful when building cipherlists out of lower-level primitives such as 207B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers. When in 208doubt, include B<!eNULL> in your cipherlist. 209 210=item B<aNULL> 211 212The cipher suites offering no authentication. This is currently the anonymous 213DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable 214to "man in the middle" attacks and so their use is discouraged. 215These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL> 216ciphers. 217Be careful when building cipherlists out of lower-level primitives such as 218B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers. 219When in doubt, include B<!aNULL> in your cipherlist. 220 221=item B<kRSA>, B<aRSA>, B<RSA> 222 223Cipher suites using RSA key exchange or authentication. B<RSA> is an alias for 224B<kRSA>. 225 226=item B<kDHr>, B<kDHd>, B<kDH> 227 228Cipher suites using static DH key agreement and DH certificates signed by CAs 229with RSA and DSS keys or either respectively. 230All these cipher suites have been removed in OpenSSL 1.1.0. 231 232=item B<kDHE>, B<kEDH>, B<DH> 233 234Cipher suites using ephemeral DH key agreement, including anonymous cipher 235suites. 236 237=item B<DHE>, B<EDH> 238 239Cipher suites using authenticated ephemeral DH key agreement. 240 241=item B<ADH> 242 243Anonymous DH cipher suites, note that this does not include anonymous Elliptic 244Curve DH (ECDH) cipher suites. 245 246=item B<kEECDH>, B<kECDHE>, B<ECDH> 247 248Cipher suites using ephemeral ECDH key agreement, including anonymous 249cipher suites. 250 251=item B<ECDHE>, B<EECDH> 252 253Cipher suites using authenticated ephemeral ECDH key agreement. 254 255=item B<AECDH> 256 257Anonymous Elliptic Curve Diffie-Hellman cipher suites. 258 259=item B<aDSS>, B<DSS> 260 261Cipher suites using DSS authentication, i.e. the certificates carry DSS keys. 262 263=item B<aDH> 264 265Cipher suites effectively using DH authentication, i.e. the certificates carry 266DH keys. 267All these cipher suites have been removed in OpenSSL 1.1.0. 268 269=item B<aECDSA>, B<ECDSA> 270 271Cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA 272keys. 273 274=item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3> 275 276Lists cipher suites which are only supported in at least TLS v1.2, TLS v1.0 or 277SSL v3.0 respectively. 278Note: there are no cipher suites specific to TLS v1.1. 279Since this is only the minimum version, if, for example, TLSv1.0 is negotiated 280then both TLSv1.0 and SSLv3.0 cipher suites are available. 281 282Note: these cipher strings B<do not> change the negotiated version of SSL or 283TLS, they only affect the list of available cipher suites. 284 285=item B<AES128>, B<AES256>, B<AES> 286 287cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES. 288 289=item B<AESGCM> 290 291AES in Galois Counter Mode (GCM): these cipher suites are only supported 292in TLS v1.2. 293 294=item B<AESCCM>, B<AESCCM8> 295 296AES in Cipher Block Chaining - Message Authentication Mode (CCM): these 297cipher suites are only supported in TLS v1.2.
