This command is used to generate list of algorithms or disabled features.
OPTIONS
-help
Display a usage message.
-1
List the commands, digest-commands, or cipher-commands in a single column. If used, this option must be given first.
-commands
Display a list of standard commands.
-digest-commands
Display a list of message digest commands, which are typically used as input to the dgst(1) or speed(1) commands.
-digest-algorithms
Display a list of message digest algorithms. If a line is of the form foo => bar then foo is an alias for the official algorithm name, bar.
-cipher-commands
Display a list of cipher commands, which are typically used as input to the dgst(1) or speed(1) commands.
-cipher-algorithms
Display a list of cipher algorithms. If a line is of the form foo => bar then foo is an alias for the official algorithm name, bar.
-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.
-public-key-methods
Display a list of public key method OIDs: this also includes public key methods without an associated ASN.1 method, for example, KDF algorithms.
-disabled
Display a list of disabled features, those that were compiled out of the installation.
