libwget-hash(3)

💖 libwget-hash(3) 💖

okay bestie, listen up — this is the libwget-hash page from the Library Functions Manual, and it's literally your whole cheat sheet for hash convenience functions. hashing is just ✨vibes✨ but with math, and this page is the group chat where all the hash girlies hang out. no cap.

🌸 NAME 🌸

libwget-hash — Hash convenience functions

like. that's it. that's the name. it does hashes, conveniently. slay.

---

🦋 SYNOPSIS 🦋

🎀 Files

• hashfile.c — Hashing functions. that's the file, bestie, that's where the magic lives 💅

🎀 Typedefs

• typedef struct wget_hash_hd_st wget_hash_hd — Type for hash / digest routines. this is the little handle you hold onto when you're doing hash stuff. main character energy fr.

🎀 Enumerations

• enum wget_digest_algorithm { WGET_DIGTYPE_UNKNOWN = 0, WGET_DIGTYPE_MD5, WGET_DIGTYPE_SHA1, WGET_DIGTYPE_RMD160, WGET_DIGTYPE_MD2, WGET_DIGTYPE_SHA256, WGET_DIGTYPE_SHA384, WGET_DIGTYPE_SHA512, WGET_DIGTYPE_SHA224, WGET_DIGTYPE_MAX } — Enumeration of different hash digest algorithms. a whole menu of algorithms, pick your fave, they're all iconic in their own way.

🎀 Functions

void wget_hash_printf_hex (wget_digest_algorithm algorithm, char *out,
    size_t outsize, const char *fmt,...)

one function. one function that does SO much. we love her.

🌈 Detailed Description 🌈

Provides Hash helper functions

that's the whole thing. it provides hash helper functions. short, sweet, does not overexplain, respects your time. periodt. 💅

👑 Enumeration Type Documentation 👑

✨ enum wget_digest_algorithm ✨

Enumeration of different hash digest algorithms. here come the girls, one by one:

Enumerator

• WGET_DIGTYPE_UNKNOWN — Indicates 'Unknown hash algorithm', returned by wget_hash_get_algorithm(). it's the "idk her" of the enum, no shade.
• WGET_DIGTYPE_MD5 — Type 'MD5' digest. the classic, the OG, still showing up to the party.
• WGET_DIGTYPE_SHA1 — Type SHA1 digest. she's been around a while, she knows everybody.
• WGET_DIGTYPE_RMD160 — Type RMD160 digest. the underrated one. give her a chance 🥺
• WGET_DIGTYPE_MD2 — Type 'MD2' digest. vintage. retro. a little mysterious.
• WGET_DIGTYPE_SHA256 — Type 'SHA256' digest. the it-girl. the moment. the one everybody's talking about 🔥
• WGET_DIGTYPE_SHA384 — Type 'SHA384' digest. SHA256's taller sister, same energy, more to love.
• WGET_DIGTYPE_SHA512 — Type 'SHA512' digest. big. bold. giving maximum security main character. 👑
• WGET_DIGTYPE_SHA224 — Type 'SHA224' digest. the compact cutie, does the same job, smaller footprint, still ate. 🍓
• WGET_DIGTYPE_MAX — Number of digest types. not a real algorithm bestie, she's just the counter at the end. she counts the girls. she's the bouncer at the door. 💀

💜 Function Documentation 💜

🧚 void wget_hash_printf_hex (wget_digest_algorithm algorithm, char * out, size_t outsize, const char * fmt, ...)

Parameters

• algorithm — The hash algorithm to use. pick from the enum above, choose your fighter.
• out — Output string buffer. where the pretty hex result gets written, bestie.
• outsize — Size of output string buffer. you gotta tell her how much room she has. do NOT skimp on this, she WILL get upset.
• fmt — Printf-like format specifier. yes, the printf-style one you already know and love.
• ... — List of arguments. all the little guys that go into the format string.

Calculate the hash from the string generated via the printf-style fmt and the following arguments and place it as hexadecimal string into out.

so like — you give her a format string, she builds the string for you, hashes it, and hands you back the hex. one stop shop. no extra steps. she's efficient like that. ✨

The ideal length of out would be wget_hash_get_len(type) * 2 + 1.

that's the math, bestie. wget_hash_get_len(type) * 2 + 1. that's how much buffer you want so nobody gets hurt. it's giving "measure twice, cut once" but make it hexadecimal. 📏

yeah, no human wrote this page, it's a robot being a good little documentarian. we still love her though. 🎀
