💫 EVP_WHIRLPOOL 💫

okay bestie, so this is the OpenSSL manual page for EVP_WHIRLPOOL — yes, 3ossl is the manual name, that's just how the library tags these things 🎀

✨ NAME ✨

EVP_whirlpool — WHIRLPOOL, but for EVP. that's the whole vibe 💅

🦋 SYNOPSIS 🦋

#include <openssl/evp.h>

const EVP_MD *EVP_whirlpool(void);

🌸 DESCRIPTION 🌸

so. WHIRLPOOL is a cryptographic hash function, standardized in ISO/IEC 10118-3:2004, and it was designed by Vincent Rijmen and Paulo S. L. M. Barreto. two absolute icons, no cap 👑

big important heads-up though: this implementation is only available with the legacy provider. legacy. like, vintage. so make sure you've got that provider loaded or this whole thing is not gonna happen for you 😭

  • EVP_whirlpool() — returns the WHIRLPOOL algorithm, and that algorithm takes your input and produces a message digest of 512-bits. five hundred and twelve. iconic length, honestly.

👑 NOTES 👑

okay listen, devs — be aware that calling this function multiple times has negative performance implications. like it works, but it's giving unnecessary ✨struggle✨. so instead, consider using EVP_MD_fetch(3) with EVP_MD-WHIRLPOOL(7). and if you wanna know more, go read "Performance" in crypto(7). iyk...

🍓 RETURN VALUES 🍓

these functions return an EVP_MD structure, and that structure contains the implementation of the message digest. if you wanna know all the details of the EVP_MD structure, check EVP_MD_meth_new(3). it's all there, fr fr 🫶

ISO/IEC 10118-3:2004. that's it, that's the standard, periodt 💖
