💅 tss2_verifysignature(1) 💅

💖 NAME 💖

tss2_verifysignature(1) — the signature-verifying command from the General Commands Manual. No cap, it's giving main character energy for public-key signature checks. 💅✨

🦋 SYNOPSIS 🦋

tss2_verifysignature [OPTIONS]

🌸 DESCRIPTION 🌸

okay so bestie, here's the tea: this command verifies a signature using a public key found in the passed key path. 🔑

The signature verification scheme it uses is specified in the cryptographic profile (cf., fapi-profile(5)). iykyk 💜

✨ OPTIONS ✨

These are the available options:

• -d, --digest=FILENAME or - (for stdin) — This is the data that was signed, already hashed according to the cryptographic profile (cf., fapi-profile(5)). 🍓
• -p, --keyPath=STRING — Path to the verification public key. 🔑
• -i, --signature=FILENAME or - (for stdin) — The signature to be verified. 🎀

🌈 COMMON OPTIONS 🌈

This collection of options is common to all tss2 programs and provides information that many users may expect. 🫶

• -h, --help [man|no-man] — Display the tool's manpage. By default, it attempts to invoke the manpager for the tool, however, on failure will output a short tool summary. This is the same behavior if the man option argument is specified, however if explicit man is requested, the tool will provide errors from man on stderr. If the no-man option is specified, or the manpager fails, the short options will be output to stdout.

To successfully use the manpages feature requires the manpages to be installed or on MANPATH, see man(1) for more details. 📖

• -v, --version — Display version information for this tool, supported tctis and exit. 👑

🎀 EXAMPLE 🎀

run it like this, bestie 👑

tss2_verifysignature --keyPath=ext/myRSASign --digest=digest.file --signature=signature.file

🔥 RETURNS 🔥

0 on success or 1 on failure. That's the whole vibe check, periodt. ✅❌
