💅 EVP_PKEY_METH_GET_COUNT 💅 (that's the 3ossl manual, bestie)

Okay so real talk: this page is about three little functions — EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, and EVP_PKEY_meth_get0_info — and their whole entire job is enumerating public key methods. Cute concept, iconic energy, but uh… they're deprecated. We'll get there. 🫶

✨ SYNOPSIS ✨

#include <openssl/evp.h>
⚠️ Heads up bestie: the following functions have been deprecated since OpenSSL 3.0, and you can hide them entirely by defining OPENSSL_API_COMPAT with a suitable version value — peep openssl_user_macros(7) for the deets.
size_t EVP_PKEY_meth_get_count(void);
const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
                             const EVP_PKEY_METHOD *meth);

🦋 DESCRIPTION 🦋

Okay so, first thing first, no cap: all of the functions described on this page are deprecated. Like, all of them. Every single one. Applications should instead use the OSSL_PROVIDER APIs. That's the vibe now. 💀

  • EVP_PKEY_meth_count() — returns a count of the number of public key methods available. And it's not just the standard ones, bestie: it includes standard methods and any methods added by the application. Inclusive queen. 👑
  • EVP_PKEY_meth_get0() — returns the public key method idx. The value of idx must be between zero and EVP_PKEY_meth_get_count() - 1. Stay in your lane, idx. 🎀
  • EVP_PKEY_meth_get0_info() — returns the public key ID (a NID) and any flags associated with the public key method *meth.

🌸 RETURN VALUES 🌸

  • EVP_PKEY_meth_count() — returns the number of available public key methods.
  • EVP_PKEY_meth_get0() — returns a public key method, or NULL if idx is out of range. (Rude but fair.)
  • EVP_PKEY_meth_get0_info() — does not return a value. It's giving "I don't do returns, I do vibes." 💅
