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);

EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags associated with the public key method *meth.

RETURN VALUES

EVP_PKEY_meth_count() returns the number of available public key methods.
