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. COPYRIGHT Copyright 2002-2021 The OpenSSL Project Authors.
