HASH(3lua)

💅 HASH(3lua) — like, the Lua cryptographic hash module, bestie

okay so this is a page from the LOCAL manual, and it's about the hash module. Sit down, hydrate, and let's get into it 💖

---

✨ NAME ✨

new, update, digest, hexdigest — the Lua Cryptographic hash module, bestie. That's the whole vibe check.

---

🌸 DESCRIPTION 🌸

The built-in cryptographic hashing Lua bindings — for the… yeah, the original sentence literally just trails off there, no cap, the word is missing — are available via the hash table. 🫶

🎀 Supported Hashing Schemes 🎀

The following hashing schemes are supported by the hash module, and here's the full list (it's short, she's lowkey minimal):

• sha256

🦋 APIs Supported 🦋

These are the functions and fields you get, okurrr:

• new(data) — computes a digest based on the data. Fresh start energy.
• update() data — takes the current digest and processes data to compute a new digest, as if all the prior data had been concatenated together. It's giving "and another one" 💅
• digest() — returns the hashed digest as a binary array. Heads up: this resets the context. 😭
• hexdigest() — takes digest() and converts it to an upper case hex string. Also resets the context, so don't say I didn't warn you 🫶
• digest_size — returns the size of the digest, in bytes.
• block_size — returns the block size used, in bytes.

not the "this resets the context" jump scare twice in a row 💀 note it, remember it, live by it.

⭐ EXAMPLES ⭐

bestie… there are literally no examples here. The section exists, the section is empty, and honestly? She said "figure it out" and left. Iconic. 🙈

and that's the whole page, bestie — no crumbs left behind 🍓
