48=head1 DESCRIPTION
49
50This command is used to generate list of algorithms or disabled
51features.
52
53=head1 OPTIONS
54
55=over 4
56
57=item B<-help>
58
59Display a usage message.
60
61=item B<-verbose>
62
63Displays extra information.
64The options below where verbosity applies say a bit more about what that means.
65
66=item B<-select> I<name>
67
68Only list algorithms that match this name.
69
70=item B<-1>
71
72List the commands, digest-commands, or cipher-commands in a single column.
73If used, this option must be given first.
74
75=item B<-commands>
76
77Display a list of standard commands.
78
79=item B<-standard-commands>
80
81List of standard commands.
82
83=item B<-digest-commands>
84
85This option is deprecated. Use B<digest-algorithms> instead.
86
87Display a list of message digest commands, which are typically used
88as input to the L<openssl-dgst(1)> or L<openssl-speed(1)> commands.
89
90=item B<-cipher-commands>
91
92This option is deprecated. Use B<cipher-algorithms> instead.
93
94Display a list of cipher commands, which are typically used as input
95to the L<openssl-enc(1)> or L<openssl-speed(1)> commands.
96
97=item B<-cipher-algorithms>, B<-digest-algorithms>, B<-kdf-algorithms>,
98B<-mac-algorithms>,
99
100Display a list of symmetric cipher, digest, kdf and mac algorithms.
101See L</Display of algorithm names> for a description of how names are
102displayed.
103
104In verbose mode, the algorithms provided by a provider will get additional
105information on what parameters each implementation supports.
106
107=item B<-random-instances>
108
109List the primary, public and private random number generator details.
110
111=item B<-random-generators>
112
113Display a list of random number generators.
114See L</Display of algorithm names> for a description of how names are
115displayed.
116
117=item B<-encoders>
118
119Display a list of encoders.
120See L</Display of algorithm names> for a description of how names are
121displayed.
122
123In verbose mode, the algorithms provided by a provider will get additional
124information on what parameters each implementation supports.
125
126=item B<-decoders>
127
128Display a list of decoders.
129See L</Display of algorithm names> for a description of how names are
130displayed.
131
132In verbose mode, the algorithms provided by a provider will get additional
133information on what parameters each implementation supports.
134
135=item B<-public-key-algorithms>
136
137Display a list of public key algorithms, with each algorithm as
138a block of multiple lines, all but the first are indented.
139The options B<key-exchange-algorithms>, B<kem-algorithms>,
140B<signature-algorithms>, and B<asymcipher-algorithms> will display similar info.
141
142=item B<-public-key-methods>
143
144Display a list of public key methods.
145
146=item B<-key-managers>
147
148Display a list of key managers.
149
150=item B<-key-exchange-algorithms>
151
152Display a list of key exchange algorithms.
153
154=item B<-kem-algorithms>
155
156Display a list of key encapsulation algorithms.
157
158=item B<-signature-algorithms>
159
160Display a list of signature algorithms.
161
162=item B<-asymcipher-algorithms>
163
164Display a list of asymmetric cipher algorithms.
165
166=item B<-store-loaders>
167
168Display a list of store loaders.
169
170=item B<-providers>
171
172Display a list of all loaded providers with their names, version and status.
173
174In verbose mode, the full version and all provider parameters will additionally
175be displayed.
176
177
178=item B<-engines>
179
180This option is deprecated.
181
182Display a list of loaded engines.
183
184=item B<-disabled>
185
186Display a list of disabled features, those that were compiled out
187of the installation.
188
189=item B<-objects>
190
191Display a list of built in objects, i.e. OIDs with names.  They're listed in the
192format described in L<config(5)/ASN1 Object Configuration Module>.
193
194=item B<-options> I<command>
195
196Output a two-column list of the options accepted by the specified I<command>.
197The first is the option name, and the second is a one-character indication
198of what type of parameter it takes, if any.
199This is an internal option, used for checking that the documentation
200is complete.

205
206=head2 Display of algorithm names
207
208Algorithm names may be displayed in one of two manners:
209
210=over 4
211
212=item Legacy implementations
213
214Legacy implementations will simply display the main name of the
215algorithm on a line of its own, or in the form C<<foo > bar>> to show
216that C<foo> is an alias for the main name, C<bar>
217
218=item Provided implementations
219
220Implementations from a provider are displayed like this if the
221implementation is labeled with a single name:
222
223 foo @ bar
224
225or like this if it's labeled with multiple names:
226
227 { foo1, foo2 } @bar
228
229In both cases, C<bar> is the name of the provider.

233=head1 HISTORY
234
235The B<-engines>, B<-digest-commands>, and B<-cipher-commands> options
236were deprecated in OpenSSL 3.0.
