EVP_PKEY_METH_GET_COUNT(3)          OpenSSL         EVP_PKEY_METH_GET_COUNT(3)

NAME
       EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info -
       enumerate public key methods

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);

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 idx. The value of
       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 *meth.

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

       EVP_PKEY_meth_get0() return a public key method or NULL if idx is out
       of range.

       EVP_PKEY_meth_get0_info() does not return a value.
