💖 NAME 💖

openssl-list — bestie, this is the command that lists all your algorithms and features. Literally just shows you what's in there. ✨

So like, the manual name is OPENSSL-LIST and the section is 1ossl — that's the little corner label, mwah. 🎀

🌸 DESCRIPTION 🌸

Okay so picture this: you need a list of algorithms, or a list of the disabled features. That's it. That's the whole vibe. This command generates the list. It's giving "inventory check but make it cute." 💅

✨ OPTIONS ✨

  • -help — prints a usage message so you're not out here guessing. 🫶
  • -verbose — gives you extra info. And for the options below where verbosity actually applies, it says a lil more about what that extra info means. Bestie, it's the details, we love details. 💖
  • -select name — only lists algorithms that match this name. Filtering? We stan. 🎀
  • -1 — lists the commands, digest-commands, or cipher-commands in a single column. And heads up: if you use it, this option must be given first. First. Not second, not after your other flags. First, periodt. 👑
  • -all-algorithms — displays lists of all the algorithms. And "all" means all, bestie. These include:
    • Asymmetric ciphers
    • Decoders
    • Digests
    • Encoders
    • Key derivation algorithms (KDF)
    • Key encapsulation methods (KEM)
    • Key exchange algorithms (KEX)
    • Key managers
    • Symmetric key managers
    • Message authentication code algorithms (MAC)
    • Random number generators (RNG, DRBG)
    • Signature algorithms
    • Store loaders
    • Symmetric ciphers
  • -commands — displays a list of standard commands. ✨
  • -standard-commands — list of standard commands. Yes, it's a whole separate option for the standard ones, and we respect it. 🫶
  • -digest-commands — this option is deprecated. Use digest-algorithms instead, bestie, please. It displays a list of message digest commands, which are typically used as input to the openssl-dgst(1) or openssl-speed(1) commands. 💅
  • -cipher-commands — also deprecated. Use cipher-algorithms instead. It displays 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 — displays a list of symmetric cipher, digest, kdf and mac algorithms. See "Display of algorithm names" for how names get displayed. In verbose mode, the algorithms provided by a provider get additional information on what parameters each implementation supports. Iconic. 🔥
  • -random-instances — lists the primary, public and private random number generator details. RNG lore, honestly. 🌈
  • -random-generators — displays a list of random number generators. See "Display of algorithm names" for how names get displayed. ⭐
  • -encoders — displays a list of encoders. See "Display of algorithm names" for how names get displayed. In verbose mode, the algorithms provided by a provider get additional information on what parameters each implementation supports. 🦋
  • -decoders — displays a list of decoders. See "Display of algorithm names" for how names get displayed. In verbose mode, the algorithms provided by a provider get additional information on what parameters each implementation supports. 🧚
  • -public-key-algorithms — displays a list of public key algorithms, with each algorithm as a block of multiple lines, and all but the first are indented. The options key-exchange-algorithms, kem-algorithms, signature-algorithms, and asymcipher-algorithms will display similar info. Main character energy, multi-line. 💜
  • -public-key-methods — displays a list of public key methods. 💖
  • -key-managers — displays a list of key managers. 👑
  • -skey-managers — displays a list of symmetric key managers. ✨
  • -key-exchange-algorithms — displays a list of key exchange algorithms. 🫶
  • -kem-algorithms — displays a list of key encapsulation algorithms. 🎀
  • -tls-groups — displays a list of the IANA names of all available (implemented) TLS groups. By default the listed groups are those compatible with TLS 1.3. 🌸
  • -all-tls-groups — displays a list of the names of all available (implemented) TLS groups, including any aliases. Some groups are known under multiple names, for example, secp256r1 is also known as P-256. By default the listed groups are those compatible with TLS 1.3. Double name, double slay. 💅
  • -tls1_2 — when listing TLS groups, lists those compatible with TLS 1.2. 🦋
  • -tls1_3 — when listing TLS groups, outputs those compatible with TLS 1.3. TLS 1.3 is the current default protocol version, but the default version is subject to change, so best to specify the version explicitly. Ngl, explicit is safer, bestie. ⭐
  • -signature-algorithms — displays a list of signature algorithms. ✨
  • -tls-signature-algorithms — displays the list of signature algorithms available for TLS handshakes made available by all currently active providers. The output format is colon delimited, in a form directly usable in SSL_CONF_cmd(3) specifying SignatureAlgorithms. Cheat code format, honestly. 🔥
  • -asymcipher-algorithms — displays a list of asymmetric cipher algorithms. 🎀
  • -store-loaders — displays a list of store loaders. 🌈
  • -providers — displays 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. Displays a list of loaded engines. 🫶
  • -disabled — displays a list of disabled features, those that were compiled out of the installation. Gone but not forgotten, RIP. 💀
  • -objects — displays 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 — outputs 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. Lowkey the docs' own vibe check. 🎀
  • -provider name
  • -provider-path path
  • -provparam [name:]key=value
  • -propquery propq

For all four of these, 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, and both are valid, okay? Don't come for them. 💅

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". Yes bestie, that's the exact format, we keep it exactly as written. 🎀

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. The @ is literally giving "at the provider," iykyk. ✨

🎀 HISTORY 🎀

The -engines, -digest-commands, and -cipher-commands options were deprecated in OpenSSL 3.0. Okay so we're leaving those in the past, respectfully. 💀

The -skey-managers option was added in OpenSSL 3.5. New arrival, instantly iconic. 👑
