💅 SIGGEN(8) — like, the signature gathering utility, bestie

okay so picture this: you're deep in the System Manager's Manual side of your terminal, and this little icon siggen is sitting there being all "let me show you the hash values for your files." That's literally it. That's the whole vibe. It's the signature gathering utility for Tripwire, and honestly? It ate. 🎀

✨ SYNOPSIS ✨

siggen [ -t|--terse ] [ -h|--hexadecimal ] [ -a|--all ] [ -C|--CRC32 ] [
-S|--SHA ] [ -h|--HAVAL ] file1,,,

no cap, that's the whole summoning ritual right there 🫶 (and yes, -h shows up twice in there — that's how the man page lives, we don't question it, we just vibe with it 💀)

🌸 DESCRIPTION 🌸

siggen is a utility that displays the hash function values for the specified files. that's the entire personality. it looks at your files and is like "here's the math, bestie ✨". lowkey iconic.

💖 OPTIONS 💖

here's the menu, and every single item matters, so don't skip, iykyk 👑

  • -t, --terse — Terse mode, aka the no-yapping setting. Prints requested hashes for a given file on one line, delimited by spaces, with no extraneous information. just the facts. 🧚
  • -h, --hexadecimal — Display results in hexadecimal rather than base64 notation. your numbers, but make them hex 💅
  • -a, --all — Display all hash function values. this is the default, so it's giving main character energy without even trying 👑
  • -C, --CRC32 — Display CRC-32, POSIX 1003.2 compliant 32-bit Cyclic Redundancy Check. say that five times fast 😭
  • -M, --MD5 — Display MD5, the RSA Data Security, Inc. Message Digest Algorithm. classic. vintage. still in the options list fr fr 🔥
  • -S, --SHA — Display SHA, Tripwire's implementation of the NIST Secure Hash Standard, SHS (NIST FIPS 180). very official, very real, very much a whole thing ⭐
  • -H, --HAVAL — Display Haval value, a 128-bit hash code. cute little 128-bit moment 🦋
  • file1 [ file2... ] — List of filesystem objects for which to display values. your lineup. your roster. the files getting the treatment 🌸
ok bestie real talk for one sec: the options list has -M, --MD5 but the SYNOPSIS above doesn't show it, and -h gets used for both --hexadecimal and --HAVAL with -H being HAVAL's short form. that's just literally what the page says, so i'm passing it straight to you with zero edits 💜

🦋 EXIT STATUS 🦋

siggen exits 0 on success, 1 on error. that's it. clean, simple, no drama 💀
