The value of B<idx> 30must be between zero and EVP_PKEY_meth_get_count() - 1. 31 32EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any flags 33associated with the public key method B<*meth>. 34 35=head1 RETURN VALUES 36 37EVP_PKEY_meth_count() returns the number of available public key methods. 38 39EVP_PKEY_meth_get0() return a public key method or B<NULL> if B<idx> is 40out of range. 41 42EVP_PKEY_meth_get0_info() does not return a value. 43 44=head1 SEE ALSO 45 46L<EVP_PKEY_new(3)> 47 48=head1 HISTORY 49 50All of these functions were deprecated in OpenSSL 3.0. 51 52=head1 COPYRIGHT 53 54Copyright 2002-2021 The OpenSSL Project Authors.
