📝 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 — 1️⃣ 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 openssl-dgst(1) or openssl-speed(1).
• -cipher-commands — ⚠️ This option is deprecated. Use -cipher-algorithms instead. Display a list of cipher commands, which are typically used as input to openssl-enc(1) or openssl-speed(1).
• -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.
• -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 — 🏭 See “Provider Options” in openssl(1), provider(7), and property(7).
• -provider-path path — 🗺️ See “Provider Options” in openssl(1), provider(7), and property(7).
• -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.
