SHA3-512SUM(1)

💅 SHA3-512SUM(1) — like, the whole manual page, bestie

okay so this is sha3-512sum, straight out of the sha3sum package (yes, that's the manual name, we're being thorough 💖). General Commands Manual energy. Periodt.

✨ NAME ✨

sha3-512sum — compute and check SHA3-512 message digests 🫶

---

🦋 SYNOPSIS 🦋

sha3-512sum [-u | -l | -b | -c] [-R rate] [-C capacity] [-N output-size]
[-S state-size] [-W word-size] [-Z squeeze-count] [-vxz] [file ...]

---

🌸 DESCRIPTION 🌸

It prints or checks SHA3-512 checksums, no cap. If you give it no file at all, or if the file is literally -, it reads from standard input. iconic behavior honestly.

• -u — output checksums in upper-case hexadecimal. loud and proud.
• -l — output checksums in lower-case hexadecimal. this is the default, so you get it for free ✨
• -b — output checksums in binary representation. heads up: this suppresses the filenames and checksum delimiters, so literally only the checksums get printed. no extra decoration.
• -c — read SHA3-512 sums from the file and check them against the files on your system. the input files should be formatted like this program's output, or similar. ⚠️ real talk: this is not going to work if any of the filenames in the input file start with a regular space or horizontal tab, or if they contain a line feed, carriage return, or form feed — unless you also use the -z option. consider yourself warned 💀
• -v — print the hashing parameters. transparency queen.
• -x — convert input files from hexadecimal form to binary form before calculating the checksums.
• -z — lines end with NUL instead of LF. if you use it with -c, this applies to the files being read (not the output), but it will also apply more strict parsing and allow any whitespace in file names. so, like, the glow-up for messy filenames 🌈

🎀 the hashing-parameter options, aka the spicy ones

the following options change the hashing parameters:

• -R rate — change the rate.
• -C capacity — change the capacity.
• -N, -O output-size — change the output size.
• -S, -B state-size — change the state size.
• -W word-size — change the word size.
• -Z squeeze-count — change the number of squeezes that is performed.

---

🔥 EXIT STATUS 🔥

• 0 — successful completion. we ate. 👑
• 1 — checksums did not match or a file did not exist. 😭
• 2 — an error occurred. 💀

🍓 NOTES 🍓

all commands in the sha3sum package let you change the hashing parameters. however — and this is the important part — it's only intended to be used with keccaksum(1), or if you know what you are doing. the exception is -N, which is intended to always be used with shake128sum(1), shake256sum(1), shake512sum(1), rawshake128sum(1), rawshake256sum(1), and rawshake512sum(1). iykyk 🧚

fr fr don't go changing parameters just for the vibes unless you actually know what you're doing, bestie.

okay that's the whole page, nothing skipped, nothing dropped 🫶 this came to you from the SHA3SUM source / SHA3-512SUM(1) page in the General Commands Manual — mwah, go hash something slay 💖✨🎀
