OPENSSL-PKEYPARAM(1ossl)

🌸 NAME 🌸

OPENSSL-PKEYPARAM(1ossl) bestie! This is the page for openssl-pkeyparam — the public key algorithm parameter processing command. It's giving “I process public key algorithm parameters,” and honestly, slay.

✨ SYNOPSIS ✨

       openssl pkeyparam [-help] [-in filename] [-out filename] [-text]
       [-noout] [-check] [-engine id] [-provider name] [-provider-path path]
       [-provparam [name:]key=value] [-propquery propq]

💖 DESCRIPTION 💖

Okay so openssl pkeyparam processes public key algorithm parameters. You can check them for correctness, and their components can be printed out. That's the whole vibe — parameters get processed, checked, and shown off. ✨

🎀 OPTIONS 🎀

• -help — prints out a usage message. The classic “what do I do again?” button.
• -in filename — says where to read parameters from. If you don't specify it, it reads from standard input. Bestie, it's lowkey a mind reader.
• -out filename — says where to write parameters to. If you don't specify it, it writes to standard output. The output filename can be the same as the input filename, which leads to replacing the file contents. And heads up: file I/O is not atomic. The output file is truncated and then written. Not us getting dramatic, that's just literally what it does 💀.
• -text — prints out the parameters in plain text in addition to the encoded version. Both. Because why choose?
• -noout — do not output the encoded version of the parameters. Sometimes you just don't want the encoded version, periodt.
• -check — checks the correctness of parameters. It's the vibe check for your parameters, no cap.
• -engine id — see "Engine Options" in openssl(1). This option is deprecated.
• -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).
• -provparam [name:]key=value — see "Provider Options" in openssl(1), provider(7), and property(7).
• -propquery propq — see "Provider Options" in openssl(1), provider(7), and property(7).

🌟 EXAMPLES 🌟

Print out text version of parameters:

        openssl pkeyparam -in param.pem -text

🦋 NOTES 🦋

There are no -inform or -outform options for this command, bestie, and that's on purpose: only PEM format is supported because the key type is determined by the PEM headers. Iykyk. 🫶
