SHAKE512SUM(1)

💅 SHAKE512SUM — like, the whole vibe

okay so bestie, welcome to shake512sum — it lives in the General Commands Manual section and it's about to compute and check SHAKE512 message digests for you. no cap. ✨

---

✨ SYNOPSIS ✨

shake512sum [-u | -l | -b | -c] [-R rate] [-C capacity] [-N output-size]
[-S state-size] [-W word-size] [-Z squeeze-count] [-vxz] [file ...]

---

🦋 DESCRIPTION 🦋

So basically: this icon prints or checks SHAKE512 checksums. that's the whole gig. 🎀

If you give it no file at all — or if the file is literally just - — it reads standard input. yes queen, stdin is a valid vibe. 🫶

• -u — outputs the checksums in upper-case hexadecimal. shouting, but make it hash. 🔥
• -l — outputs the checksums in lower-case hexadecimal. this is the default, so it's already main character energy.
• -b — outputs the checksums in binary representation. heads up: this suppresses the filenames and checksum delimiters — only the checksums get printed. clean. minimal. 💅
• -c — reads the SHAKE512 sums from the file and checks them against the files on your system. the input files should be formatted as the output of this program, or similarly. ⚠️ big warning: this is genuinely 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. iykyk. 😭
• -v — prints the hashing parameters. show me your settings bestie. 👀
• -x — converts input files from hexadecimal form to binary form before calculating the checksums. glow-up the input first. 🌈
• -z — lines end with NUL instead of LF. if you use it with -c, this applies to the read files (not the output), but it will also apply more strict parsing and allow any whitespace in file names. chaos mode, but legally. 🌸

🎀 the options that change the hashing parameters 🎀

these ones are the actual knobs. give them a spin:

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

---

⭐ EXIT STATUS ⭐

• 0 — successful completion. slay, it worked. 💖
• 1 — the checksums did not match, or a file did not exist. 💀
• 2 — an error occurred. it's giving disaster, but at least it told you.

🧚 NOTES 🧚

okay this part is important so sit up:

All commands in the sha3sum package allow changing the hashing parameters. HOWEVER — it's only intended to be used with keccaksum(1), or if you know what you are doing. 🚨

The one exception? -N, which is intended to always be used with shake128sum(1), shake256sum(1), shake512sum(1), rawshake128sum(1), rawshake256sum(1), and rawshake512sum(1). those are its besties, periodt. 💜

🌸 and that's the tea! 🌸

this page came to you from the SHA3SUM package, and yeah the footer is literally just SHA3SUM and SHAKE512SUM(1) — no date on this one bestie, we checked. 💅 go hash something gorgeous. ✨
