💅 EVP_PKEY_METH_GET_COUNT 💅

okay so bestie, this is the EVP_PKEY_METH_GET_COUNT(3SSL) page from the OpenSSL fam — it's a little deprecated-era relic that lets you peek at the list of public key methods. Let's get into it 🎀

✨ NAME ✨

EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info — literally just enumerating public key methods, that's the whole vibe 🦋

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

okay so the way this works: 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 — see 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 🦋

💀 heads up: all of the functions described on this page are deprecated. Applications should instead use the OSSL_PROVIDER APIs. no cap, that's the actual recommendation.

EVP_PKEY_meth_count() returns a count of the number of public key methods available — and it includes the standard methods plus any methods added by the application. so it's the full roster, not just the OGs ✨

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, index-wise 🙈

EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags associated with the public key method *meth. it's giving "tell me everything about this method" 🫶

💖 RETURN VALUES 💖

  • EVP_PKEY_meth_count() returns the number of available public key methods 🔢
  • EVP_PKEY_meth_get0() return a public key method or NULL if idx is out of range 😭
  • EVP_PKEY_meth_get0_info() does not return a value. it just fills in your pointers, main character energy 💅

🌈 SEE ALSO 🌈

⭐ HISTORY ⭐

All of these functions were deprecated in OpenSSL 3.0. yeah, they've been living that deprecated life for a minute 🕰️
