💖 EVP_RIPEMD160 — bestie edition 💖

okay so this is the EVP_RIPEMD160 page from the OpenSSL manual, and it's lowkey a little relic-core moment. it's short, it's sweet, it's giving "obscure hash function that still shows up in your compliance checklist" ✨

🎀 NAME 🎀

EVP_ripemd160 — that's RIPEMD160 For EVP babes. that's the whole name. short king energy 👑

✨ SYNOPSIS ✨

the way you summon it is literally this, copy it exactly, no improvising:

#include <openssl/evp.h>

const EVP_MD *EVP_ripemd160(void);

🌸 DESCRIPTION 🌸

so RIPEMD-160 is a cryptographic hash function that got first published in 1996 🎂 and it belongs to the RIPEMD family — which stands for RACE Integrity Primitives Evaluation Message Digest, yes the whole mouthful, yes it's iconic, no we don't abbreviate it around here.

🚨 important tea: this implementation is only available with the legacy provider. legacy. provider. so if you're on a modern setup and it's not working, that's why bestie, that's the vibe check failing fr fr.
  • EVP_ripemd160() — this is the one and only function here. it gives you the RIPEMD-160 algorithm, which produces a 160-bit output from a given input. that's it. that's the whole thing. 160 bits of pure dedication 💅

⭐ NOTES ⭐

okay besties listen up, this is the part where I hold your hand 🫶

devs should be aware of the negative performance implications of calling this function multiple times — like, it's not free, it's not cheap, it's giving "you're doing it the slow way."

you should consider using EVP_MD_fetch(3) together with EVP_MD-RIPEMD160(7) instead. that's the glow-up path ✨

and for the full lore, see "Performance" in crypto(7) — there's a whole section about it, iykyk.

💜 RETURN VALUES 💜

these functions return an EVP_MD structure that contains the implementation of the message digest.

that's it. that's the return value. a struct, holding the goods. slay 🎀

🌈 CONFORMING TO 🌈

ISO/IEC 10118-3:2016 Dedicated Hash-Function 1 (RIPEMD-160).

yes that's a real standard, yes it's a lot of numbers, no you don't have to memorise it, just know it's official and certified 💯
