|
|
=head1 SYNOPSIS
|
|
#include <openssl/evp.h>
|
|
size_t EVP_PKEY_meth_get_count(void);
|
const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
|
void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
|
const EVP_PKEY_METHOD *meth);
|
|
=head1 DESCRIPTION
|
|
EVP_PKEY_meth_count() returns a count of the number of public key methods
|
available: it includes standard methods and any methods added by the
|
application.
|
|
EVP_PKEY_meth_get0() returns the public key method B<idx>. The value of B<idx>
|
must be between zero and EVP_PKEY_meth_get_count() - 1.
|
|
EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags
|
associated with the public key method B<*meth>.
|
|
=head1 RETURN VALUES
|
|
EVP_PKEY_meth_count() returns the number of available public key methods.
|
|
EVP_PKEY_meth_get0() return a public key method or B<NULL> if B<idx> is
