💖 NAME 💖

EVP_MD-NULL — the NULL EVP_MD implementation, bestie. That's the whole name, that's the whole vibe ✨ (this one lives in the 7ossl corner of the OpenSSL manual, iykyk).

🦋 DESCRIPTION 🦋

okay so picture this: it's full support for a NULL digest, delivered straight through the EVP_MD API 💅. And what does this algorithm actually do? Literally nothing. That's not me being shady — that's the whole job description. It returns 1 for its init, update and final methods and just… exists. No cap, that's it. 🫶

🌸 Algorithm Name 🌸

The following algorithm is available in the default provider:

  • "NULL"

she's simple, she's iconic, she's one string 👑

🎀 Gettable Parameters 🎀

This implementation supports the common gettable parameters described in EVP_MD-common(7). so if you were wondering about params, that's where the lore lives 📖✨
