EVP_PKEY_CTX_get0_pkey, EVP_PKEY_CTX_get0_peerkey - functions for accessing the EVP_PKEY associated with an EVP_PKEY_CTX
#include <openssl/evp.h> EVP_PKEY *EVP_PKEY_CTX_get0_pkey(EVP_PKEY_CTX *ctx); EVP_PKEY *EVP_PKEY_CTX_get0_peerkey(EVP_PKEY_CTX *ctx);
EVP_PKEY_CTX_get0_pkey() is used to access the EVP_PKEY associated with the given EVP_PKEY_CTX ctx. The EVP_PKEY obtained is the one used for creating the EVP_PKEY_CTX using either EVP_PKEY_CTX_new(3) or EVP_PKEY_CTX_new_from_pkey(3).
EVP_PKEY_CTX_get0_peerkey() is used to access the peer EVP_PKEY associated with the given EVP_PKEY_CTX ctx. The peer EVP_PKEY obtained is the one set using either EVP_PKEY_derive_set_peer(3) or EVP_PKEY_derive_set_peer_ex(3).
EVP_PKEY_CTX_get0_pkey() returns the EVP_PKEY associated with the EVP_PKEY_CTX or NULL if it is not set.
EVP_PKEY_CTX_get0_peerkey() returns the peer EVP_PKEY associated with the EVP_PKEY_CTX or NULL if it is not set.
The returned EVP_PKEY objects are owned by the EVP_PKEY_CTX, and therefore should not explicitly be freed by the caller.
These functions do not affect the EVP_PKEY reference count. They merely act as getter functions, and should be treated as such.
