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

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/evp.h>

       The following functions have been deprecated since OpenSSL 3.0, and can
       be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
       version value, see openssl_user_macros(7):

        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
       All of the functions described on this page are deprecated.
       Applications should instead use the OSSL_PROVIDER APIs.

       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.

SEE ALSO
       EVP_PKEY_new(3)

HISTORY
       All of these functions were deprecated in OpenSSL 3.0.
