EVP_PKEY_METH_GET_COUNT(3ossl)

💖 EVP_PKEY_METH_GET_COUNT 💖

okay bestie, welcome to the 3ossl page for EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0 and EVP_PKEY_meth_get0_info — the little trio that lets you enumerate public key methods. yes, all three, they share one page, they're a package deal 🫶

---

✨ NAME ✨

EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info — enumerate public key methods 💅

---

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

⚠️ heads up bestie: the functions below have been deprecated since OpenSSL 3.0, and you can hide them entirely by defining OPENSSL_API_COMPAT with a suitable version value — go peek at openssl_user_macros(7) for that.

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 🦋

all of the functions described on this page are deprecated. every single one. applications should instead use the OSSL_PROVIDER APIs. periodt. 😭

EVP_PKEY_meth_count() returns a count of the number of public key methods available — and it's inclusive like a good friend: it includes standard methods and any methods added by the application. 🌈

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 bestie, that range is the range 💀

EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags associated with the public key method *meth. two things at once, multitasking icon 👑

---

⭐ RETURN VALUES ⭐

• EVP_PKEY_meth_count() returns the number of available public key methods. a whole number, iconic.
• EVP_PKEY_meth_get0() return a public key method or NULL if idx is out of range. yes the original says "return" and not "returns", we don't make the rules, we just preserve them 🙈
• EVP_PKEY_meth_get0_info() does not return a value. it's giving void energy. nothing. silence. 🎀

💀 HISTORY 💀

all of these functions were deprecated in OpenSSL 3.0. rip to their relevance, they still live in the source tho 🕯️
