164 The \fBciphers\fR command converts textual OpenSSL cipher lists into ordered
165 \&\s-1SSL\s0 cipher preference lists. It can be used as a test tool to determine
166 the appropriate cipherlist.
171 Print a usage message.
174 Only list supported ciphers: those consistent with the security level, and
175 minimum and maximum protocol version. This is closer to the actual cipher list
176 an application will support.
178 \&\s-1PSK\s0 and \s-1SRP\s0 ciphers are not enabled by default: they require \fB\-psk\fR or \fB\-srp\fR
181 It also does not change the default list of supported signature algorithms.
183 On a server the list of supported ciphers might also exclude other ciphers

214 .IX Item "-ciphersuites val"
215 Sets the list of TLSv1.3 ciphersuites. This list will be combined with any
216 TLSv1.2 and below ciphersuites that have been configured. The format for this
217 list is a simple colon (\*(L":\*(R") separated list of TLSv1.3 ciphersuite names. By
218 default this value is:
221 \& TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
223 .IP "\fBcipherlist\fR" 4
224 .IX Item "cipherlist"
225 A cipher list of TLSv1.2 and below ciphersuites to convert to a cipher
226 preference list. This list will be combined with any TLSv1.3 ciphersuites that
227 have been configured. If it is not included then the default cipher list will be
228 used. The format is described below.
229 .SH "CIPHER LIST FORMAT"
230 .IX Header "CIPHER LIST FORMAT"
231 The cipher list consists of one or more \fIcipher strings\fR separated by colons.
232 Commas or spaces are also acceptable separators but colons are normally used.
234 The actual cipher string can take several different forms.
236 It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
238 It can represent a list of cipher suites containing a certain algorithm, or
239 cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
240 suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
243 Lists of cipher suites can be combined in a single cipher string using the
244 \&\fB+\fR character. This is used as a logical \fBand\fR operation. For example
245 \&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1\s0 \fBand\fR the \s-1DES\s0
248 Each cipher string can be optionally preceded by the characters \fB!\fR,
249 \&\fB\-\fR or \fB+\fR.
251 If \fB!\fR is used then the ciphers are permanently deleted from the list.
252 The ciphers deleted can never reappear in the list even if they are
255 If \fB\-\fR is used then the ciphers are deleted from the list, but some or
256 all of the ciphers can be added again by later options.
258 If \fB+\fR is used then the ciphers are moved to the end of the list. This
259 option doesn't add any new ciphers it just moves matching existing ones.
261 If none of these characters is present then the string is just interpreted
262 as a list of ciphers to be appended to the current preference list. If the
263 list includes any ciphers already present they will be ignored: that is they
264 will not moved to the end of the list.
266 The cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort the current
267 cipher list in order of encryption algorithm key length.
269 The cipher string \fB\f(CB@SECLEVEL\fB=n\fR can be used at any point to set the security
270 level to \fBn\fR, which should be a number between zero and five, inclusive.
271 See SSL_CTX_set_security_level for a description of what each level means.
273 The cipher list can be prefixed with the \fB\s-1DEFAULT\s0\fR keyword, which enables
274 the default cipher list as defined below. Unlike cipher strings,
275 this prefix may not be combined with other strings using \fB+\fR character.
276 For example, \fB\s-1DEFAULT+DES\s0\fR is not valid.
278 The content of the default list is determined at compile time and normally
279 corresponds to \fB\s-1ALL:\s0!COMPLEMENTOFDEFAULT:!eNULL\fR.

802 Some compiled versions of OpenSSL may not include all the ciphers
803 listed here because some ciphers were excluded at compile time.
805 .IX Header "EXAMPLES"
806 Verbose listing of all OpenSSL ciphers including \s-1NULL\s0 ciphers:
809 \& openssl ciphers \-v \*(AqALL:eNULL\*(Aq
812 Include all ciphers except \s-1NULL\s0 and anonymous \s-1DH\s0 then sort by
816 \& openssl ciphers \-v \*(AqALL:!ADH:@STRENGTH\*(Aq
819 Include all ciphers except ones with no encryption (eNULL) or no
820 authentication (aNULL):
823 \& openssl ciphers \-v \*(AqALL:!aNULL\*(Aq
826 Include only 3DES ciphers and then place \s-1RSA\s0 ciphers last:
829 \& openssl ciphers \-v \*(Aq3DES:+RSA\*(Aq
832 Include all \s-1RC4\s0 ciphers but leave out those without authentication:
835 \& openssl ciphers \-v \*(AqRC4:!COMPLEMENTOFDEFAULT\*(Aq
838 Include all ciphers with \s-1RSA\s0 authentication but leave out ciphers without
842 \& openssl ciphers \-v \*(AqRSA:!COMPLEMENTOFALL\*(Aq
845 Set security level to 2 and display all ciphers consistent with level 2:
848 \& openssl ciphers \-s \-v \*(AqALL:@SECLEVEL=2\*(Aq

855 The \fB\-V\fR option for the \fBciphers\fR command was added in OpenSSL 1.0.0.
857 The \fB\-stdname\fR is only available if OpenSSL is built with tracing enabled
858 (\fBenable-ssl-trace\fR argument to Configure) before OpenSSL 1.1.1.
860 The \fB\-convert\fR option was added in OpenSSL 1.1.1.
