SEXP-CONV(1)

💖 SEXP-CONV 💖

okay bestie, welcome to the Nettle tools corner of the manual universe, where the page is literally called SEXP-CONV(1) but the whole vibe is about one lil' command: nettle-hash. yes the naming is chaotic, we don't make the rules, we just read them ✨

🌸 NAME 🌸

nettle-hash — compute message digests, fr fr

🦋 SYNOPSIS 🦋

nettle-hash -a ALGORITHM [OPTIONS] [FILE]...

🎀 DESCRIPTION 🎀

So this manual page is doing the absolute most by documenting the nettle-hash command briefly — and by "briefly" we mean this page exists because the Debian GNU/Linux distribution needed it, since the original program straight up does not have a manual page. 😭 Not a vibe. Instead, it keeps its documentation in the GNU Info format. See below, bestie. 👇

nettle-hash is a program that computes various message digests. The output is different from the familiar md5sum and sha*sum family, so don't come in here expecting that exact energy. 💅

Here's the tea on how it prints stuff:

• For each file, the file name and a colon is printed first ☝️
• Unless input is read from standard input — in which case nothing is printed at all. nothing. silence. 🫥
• Then the hash is printed in chunks of 64 bits (16 hexadecimal digits) followed by the name of the algorithm. 🔥

And in raw (binary) mode? The hash is not split in chunks and is not followed by a newline. It's giving unhinged binary chaos and honestly? iconic. 💀

✨ OPTIONS ✨

This program follows the usual GNU command line syntax, with long options starting with two dashes (`-`). A summary of options is included below — for a complete description, see the Info files, bestie. 📚

• -a, --algorithm=algorithm — compute hash using algorithm. pick your fighter. 👑
• -l, --length=length — truncate digests at length octets. 🎯 Heads up though: it is an error to specify a length greater than the normal length of the selected digest. Don't do it, it's not the move.
• --raw — produce raw binary output. feral. unformatted. no newline. 😳
• --list — list supported hash algorithms. window shopping the algorithms, we love to see it 🛍️
• --help — show summary of options. your lil' rescue bestie when you forget everything 🙈
• -V, --version — show version of program. who are you, where did you come from 💜
