💅 EVP_RIPEMD160 (3ossl) — the OpenSSL girlie's guide to RIPEMD160

okay bestie, so this page is literally about EVP_ripemd160, aka RIPEMD160 For EVP ✨ (yes that's the whole NAME section, we're keeping it real).

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

const EVP_MD *EVP_ripemd160(void);

like, that's it. one include, one function. a minimalist queen 🎀

🦋 DESCRIPTION 🦋

So <rainbow>RIPEMD-160</rainbow> is a cryptographic hash function, first published in 1996, and it belongs to the RIPEMD family — which stands for RACE Integrity Primitives Evaluation Message Digest (say that five times fast, I dare you 😭).

heads up bestie: this implementation is only available with the legacy provider. lowkey not the default vibe, so if it's not loading for you, that's why 🙈

Here's the one function on this page:

  • EVP_ripemd160() — the RIPEMD-160 algorithm, which produces a 160-bit output from a given input. that's the whole job, and it ate 💅

⭐ NOTES ⭐ (the performance PSA)

okay so listen, devs: there are negative performance implications of calling this function multiple times 😭 like, it's giving "why are you like this." You should lowkey consider using EVP_MD_fetch(3) with EVP_MD-RIPEMD160(7) instead — that's the move, fr fr. 👑

Want more deets? Check out "Performance" in crypto(7) for further information. iykyk 🫶

💖 RETURN VALUES 💖

These functions return an EVP_MD structure that contains the implementation of the message digest. 🥰 If you wanna know what's inside that EVP_MD structure, see EVP_MD_meth_new(3) for details — she spills everything.

🌈 CONFORMING TO 🌈

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

certified, standards-approved, iconic. we love a compliant queen ⭐
