.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This command is used to generate list of algorithms or disabled
features.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Display a usage message.
.IP "\fB\-verbose\fR" 4
.IX Item "-verbose"
Displays extra information.
The options below where verbosity applies say a bit more about what that means.
.IP "\fB\-1\fR" 4
.IX Item "-1"
List the commands, digest-commands, or cipher-commands in a single column.
If used, this option must be given first.
.IP "\fB\-commands\fR" 4
.IX Item "-commands"
Display a list of standard commands.
.IP "\fB\-digest\-commands\fR" 4
.IX Item "-digest-commands"
Display a list of message digest commands, which are typically used
as input to the \fIopenssl\-dgst\fR\|(1) or \fIopenssl\-speed\fR\|(1) commands.
.IP "\fB\-cipher\-commands\fR" 4
.IX Item "-cipher-commands"
Display a list of cipher commands, which are typically used as input
to the \fIopenssl\-dgst\fR\|(1) or \fIopenssl\-speed\fR\|(1) commands.
.IP "\fB\-digest\-algorithms\fR, \fB\-kdf\-algorithms\fR, \fB\-mac\-algorithms\fR, \fB\-cipher\-algorithms\fR" 4
.IX Item "-digest-algorithms, -kdf-algorithms, -mac-algorithms, -cipher-algorithms"
Display a list of cipher, digest, kdf and mac algorithms.
See \*(L"Display of algorithm names\*(R" 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.
.IP "\fB\-public\-key\-methods\fR" 4
.IX Item "-public-key-methods"
Display a list of public key method OIDs.
.IP "\fB\-engines\fR" 4
.IX Item "-engines"
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 \*(L"\s-1ASN1\s0 Object Configuration Module\*(R" in \fIconfig\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.
.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.
