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.

-select name
    Only list algorithms that match this name.

-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.

-standard-commands
    List of standard commands.

-digest-commands
    This option is deprecated. Use digest-algorithms instead.

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

-cipher-commands
    This option is deprecated. Use cipher-algorithms instead.

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

-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.

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

-random-instances
    List the primary, public and private random number generator details.

-random-generators
    Display a list of random number generators. See "Display of algorithm names" for a description of how names are displayed.

-encoders
    Display a list of encoders. 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.

-decoders
    Display a list of decoders. 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. The options key-exchange-algorithms, kem-algorithms, signature-algorithms, and asymcipher-algorithms will display similar info.

-public-key-methods
    Display a list of public key methods.

-key-managers
    Display a list of key managers.

-key-exchange-algorithms
    Display a list of key exchange algorithms.

-kem-algorithms
    Display a list of key encapsulation algorithms.

-signature-algorithms
    Display a list of signature algorithms.

-asymcipher-algorithms
    Display a list of asymmetric cipher algorithms.

-store-loaders
    Display a list of store loaders.

-providers
    Display a list of all loaded providers with their names, version and status.

    In verbose mode, the full version and all provider parameters will additionally be displayed.

-engines
    This option is deprecated.

    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 "ASN1 Object Configuration Module" in config(5).

-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
-propquery propq
    See "Provider Options" in openssl(1), provider(7), and property(7).

  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.

HISTORY
The -engines, -digest-commands, and -cipher-commands options were deprecated in OpenSSL 3.0.
