EVP_PKEY_METH_GET_COUNT(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 EVP_PKEY_METH_GET_COUNT 💖

okay bestie, welcome to the OpenSSL girlies club — this one's a 3ossl page, and it's literally all about enumerating public key methods. Like, going through the list one by one, iykyk.

✨ NAME ✨

EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info — enumerate public key methods 🎀

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

so here's the tea 🫖 — these functions have been deprecated since OpenSSL 3.0, and you can hide them entirely by defining OPENSSL_API_COMPAT with a suitable version value. wanna know what "suitable" means? check openssl_user_macros(7), she explains it 💅

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 real talk first: all of the functions described on this page are deprecated. applications should instead use the OSSL_PROVIDER APIs. that's the move, bestie ✨
  • EVP_PKEY_meth_count() — returns a count of the number of public key methods available. and it's not gatekeeping either: it includes standard methods and any methods added by the application. so inclusive 💖
  • 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. (yes, that's a hard requirement, no cap.)
  • 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. sad but fair 😭
  • EVP_PKEY_meth_get0_info() — does not return a value. she's giving void energy, and honestly? iconic 💀
