NAMEEVP_PKEY_CTX_get0_libctx, EVP_PKEY_CTX_get0_propq, EVP_PKEY_CTX_get0_provider ​− functions for getting diverse information from an EVP_PKEY_CTX

---

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​EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() obtain the ​OSSL_LIB_CTX and property query string values respectively that were associated with the EVP_PKEY_CTX when it was constructed. ​EVP_PKEY_CTX_get0_provider() returns the provider associated with the ongoing EVP_PKEY_CTX operation. If the operation is performed by en ENGINE, this function returns NULL.

---

RETURN VALUES​EVP_PKEY_CTX_get0_libctx() and EVP_PKEY_CTX_get0_propq() functions return the ​OSSL_LIB_CTX and property query string associated with the EVP_PKEY_CTX or NULL if they are not set. The returned values should not be freed by the caller. ​EVP_PKEY_CTX_get0_provider() returns a provider if an operation performed by a provider is ongoing, otherwise NULL.
