NAME

openssl-list - list algorithms and features

SYNOPSIS

openssl list [-help] [-verbose] [-1] [-commands] [-digest-commands] [-digest-algorithms] [-kdf-algorithms] [-mac-algorithms] [-cipher-commands] [-cipher-algorithms] [-public-key-algorithms] [-public-key-methods] [-engines] [-disabled] [-objects] [-options command] [-provider name] [-provider_path path]

DESCRIPTION

This command is used to generate list of algorithms or disabled features.

OPTIONS

-help

Display a usage message.

-verbose

Displays extra information. The options below where verbosity applies say a bit more about what that means.

-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 openssl-speed(1) commands.

-cipher-commands

Display a list of cipher commands, which are typically used as input to the openssl-speed(1) commands.

-digest-algorithms, -kdf-algorithms, -mac-algorithms, -cipher-algorithms

Display a list of cipher, digest, kdf and mac algorithms. See "Display of algorithm names" for a description of how names are displayed.

In verbose mode, the algorithms provided by a provider will get additional information on what parameters each implementation supports.

-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.

-engines

Display a list of loaded engines.

-disabled

Display a list of disabled features, those that were compiled out of the installation.

-objects

Display a list of built in objects, i.e. OIDs with names. They're listed in the format described in -options command

Output a two-column list of the options accepted by the specified command. 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.

-provider name

-provider_path path

See Display of algorithm names

Algorithm names may be displayed in one of two manners:

Legacy implementations

Legacy implementations will simply display the main name of the algorithm on a line of its own, or in the form <foo bar>> to show that foo is an alias for the main name, bar

Provided implementations

Implementations from a provider are displayed like this if the implementation is labeled with a single name:

 foo @ bar

or like this if it's labeled with multiple names:

 { foo1, foo2 } @bar

In both cases, bar is the name of the provider.
