.IP "\fB\-cipher\-algorithms\fR, \fB\-digest\-algorithms\fR, \fB\-kdf\-algorithms\fR, \fB\-mac\-algorithms\fR," 4
.IX Item "-cipher-algorithms, -digest-algorithms, -kdf-algorithms, -mac-algorithms,"
Display a list of symmetric cipher, digest, kdf and mac algorithms.
See "Display of algorithm names" for a description of how names are
displayed.
.Sp
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
.IP \fB\-random\-instances\fR 4
.IX Item "-random-instances"
List the primary, public and private random number generator details.
.IP \fB\-random\-generators\fR 4
.IX Item "-random-generators"
Display a list of random number generators.
See "Display of algorithm names" for a description of how names are
displayed.
.IP \fB\-encoders\fR 4
.IX Item "-encoders"
Display a list of encoders.
See "Display of algorithm names" for a description of how names are
displayed.
.Sp
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
.IP \fB\-decoders\fR 4
.IX Item "-decoders"
Display a list of decoders.
See "Display of algorithm names" for a description of how names are
displayed.
.Sp
In verbose mode, the algorithms provided by a provider will get additional
information on what parameters each implementation supports.
.IP \fB\-public\-key\-algorithms\fR 4
.IX Item "-public-key-algorithms"
Display a list of public key algorithms, with each algorithm as
a block of multiple lines, all but the first are indented.
The options \fBkey-exchange-algorithms\fR, \fBkem-algorithms\fR,
\&\fBsignature-algorithms\fR, and \fBasymcipher-algorithms\fR will display similar info.
.IP \fB\-public\-key\-methods\fR 4
.IX Item "-public-key-methods"
Display a list of public key methods.
.IP \fB\-key\-managers\fR 4
.IX Item "-key-managers"
Display a list of key managers.
.IP \fB\-key\-exchange\-algorithms\fR 4
.IX Item "-key-exchange-algorithms"
Display a list of key exchange algorithms.
.IP \fB\-kem\-algorithms\fR 4
.IX Item "-kem-algorithms"
Display a list of key encapsulation algorithms.
.IP \fB\-signature\-algorithms\fR 4
.IX Item "-signature-algorithms"
Display a list of signature algorithms.
.IP \fB\-asymcipher\-algorithms\fR 4
.IX Item "-asymcipher-algorithms"

.IP \fB\-store\-loaders\fR 4
.IX Item "-store-loaders"
Display a list of store loaders.
.IP \fB\-providers\fR 4
.IX Item "-providers"

be displayed.
.IP \fB\-engines\fR 4
.IX Item "-engines"
This option is deprecated.
.Sp
Display a list of loaded engines.
.IP \fB\-disabled\fR 4
.IX Item "-disabled"
Display a list of disabled features, those that were compiled out
of the installation.
.IP \fB\-objects\fR 4
.IX Item "-objects"
Display a list of built in objects, i.e. OIDs with names.  They're listed in the
format described in "ASN1 Object Configuration Module" in \fBconfig\fR\|(5).
.IP "\fB\-options\fR \fIcommand\fR" 4
.IX Item "-options command"
Output a two-column list of the options accepted by the specified \fIcommand\fR.
The first is the option name, and the second is a one-character indication
of what type of parameter it takes, if any.
This is an internal option, used for checking that the documentation
is complete.
.IP "\fB\-provider\fR \fIname\fR" 4
.IX Item "-provider name"
.PD 0
.IP "\fB\-provider\-path\fR \fIpath\fR" 4

.SS "Display of algorithm names"
.IX Subsection "Display of algorithm names"
Algorithm names may be displayed in one of two manners:
.IP "Legacy implementations" 4
.IX Item "Legacy implementations"
Legacy implementations will simply display the main name of the
algorithm on a line of its own, or in the form \f(CW\*(C`<foo \*(C'\fR bar>> to show
that \f(CW\*(C`foo\*(C'\fR is an alias for the main name, \f(CW\*(C`bar\*(C'\fR
.IP "Provided implementations" 4
.IX Item "Provided implementations"
Implementations from a provider are displayed like this if the
implementation is labeled with a single name:
.Sp
.Vb 1
\& foo @ bar
.Ve
.Sp
or like this if it's labeled with multiple names:
.Sp
.Vb 1
\& { foo1, foo2 } @bar
.Ve
.Sp
In both cases, \f(CW\*(C`bar\*(C'\fR is the name of the provider.
