- functions for getting diverse information from an EVP_PKEY_CTX
|
|
|
|
=head1 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);
|
|
|
|
=head1 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 B<EVP_PKEY_CTX> operation. If the operation is performed by
|
|
en B<ENGINE>, this function returns NULL.
|
|
|
|
=head1 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
