EVP_PKEY_CTX_GET0_PKEY(3ossl) OpenSSL EVP_PKEY_CTX_GET0_PKEY(3ossl)
NAME
EVP_PKEY_CTX_get0_pkey, EVP_PKEY_CTX_get0_peerkey - functions for
accessing the EVP_PKEY associated with an EVP_PKEY_CTX
SYNOPSIS
#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);
DESCRIPTION
EVP_PKEY_CTX_get0_pkey(3) 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).
RETURN VALUES
EVP_PKEY_CTX_get0_pkey(3) 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.
