SYNOPSIS

10        #include <openssl/evp.h>
11
12       The following functions have been deprecated since OpenSSL 3.0, and can
13       be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
14       version value, see openssl_user_macros(7):
15
16        size_t EVP_PKEY_meth_get_count(void);
17        const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
18        void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
19                                     const EVP_PKEY_METHOD *meth);

DESCRIPTION

22       All of the functions described on this page are deprecated.
23       Applications should instead use the OSSL_PROVIDER APIs.
24
25       EVP_PKEY_meth_count() returns a count of the number of public key
26       methods available: it includes standard methods and any methods added
27       by the application.
28
29       EVP_PKEY_meth_get0() returns the public key method idx. The value of
30       idx must be between zero and EVP_PKEY_meth_get_count() - 1.
31
32       EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any
33       flags associated with the public key method *meth.
34

RETURN VALUES

36       EVP_PKEY_meth_count() returns the number of available public key
37       methods.
38
39       EVP_PKEY_meth_get0() return a public key method or NULL if idx is out
40       of range.
41
42       EVP_PKEY_meth_get0_info() does not return a value.
