openssl-list - list algorithms and features
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]
This command is used to generate list of algorithms or disabled features.
Display a usage message.
Displays extra information. The options below where verbosity applies say a bit more about what that means.
List the commands, digest-commands, or cipher-commands in a single column. If used, this option must be given first.
Display a list of standard commands.
Display a list of message digest commands, which are typically used as input to the openssl-speed(1) commands.
Display a list of cipher commands, which are typically used as input to the openssl-speed(1) commands.
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.
Display a list of public key algorithms, with each algorithm as a block of multiple lines, all but the first are indented.
Display a list of public key method OIDs.
Display a list of loaded engines.
Display a list of disabled features, those that were compiled out of the installation.
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.
Algorithm names may be displayed in one of two manners:
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
Implementations from a provider are displayed like this if the implementation is labeled with a single name:
foo @ baror like this if it's labeled with multiple names:
{ foo1, foo2 } @barIn both cases, bar is the name of the provider.
