💖 EVP_PKEY_CTX_GET0_LIBCTX 💖

okay bestie, welcome to the OpenSSL manual, section 3SSL, and this one's called EVP_PKEY_CTX_GET0_LIBCTX. yes the name is a whole mouthful, we're getting through it together 🫶

✨ NAME ✨

EVP_PKEY_CTX_get0_libctx, EVP_PKEY_CTX_get0_propq, EVP_PKEY_CTX_get0_provider — the lil functions that get ~diverse information~ out of an EVP_PKEY_CTX. it's giving detective energy 🔍

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

OSSL_LIB_CTX *EVP_PKEY_CTX_get0_libctx(EVP_PKEY_CTX *ctx);
const char *EVP_PKEY_CTX_get0_propq(const EVP_PKEY_CTX *ctx);
const OSSL_PROVIDER *EVP_PKEY_CTX_get0_provider(const EVP_PKEY_CTX *ctx);

🦋 DESCRIPTION 🦋

so EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() hand you the OSSL_LIB_CTX and the property query string values respectively — the exact ones that got associated with the EVP_PKEY_CTX back when it was constructed. it's like, the receipts of how your ctx was born 👑

and EVP_PKEY_CTX_get0_provider() hits you with the provider associated with the ongoing EVP_PKEY_CTX operation. currently-in-progress vibes only 💅

💜 RETURN VALUES 💜

EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() return the OSSL_LIB_CTX and property query string associated with the EVP_PKEY_CTX — or NULL if they are not set.

🚨 bestie listen: the returned values should not be freed by the caller. do not touch. hands off. not yours. 🙈

EVP_PKEY_CTX_get0_provider() returns a provider if an operation performed by a provider is ongoing, otherwise NULL.
