NAME

6       EVP_PKEY_meth_get_count, EVP_PKEY_meth_get0, EVP_PKEY_meth_get0_info -
7       enumerate public key methods

SYNOPSIS

10        #include <openssl/evp.h>
11
12        size_t EVP_PKEY_meth_get_count(void);
13        const EVP_PKEY_METHOD *EVP_PKEY_meth_get0(size_t idx);
14        void EVP_PKEY_meth_get0_info(int *ppkey_id, int *pflags,
15                                     const EVP_PKEY_METHOD *meth);
16

DESCRIPTION

18       EVP_PKEY_meth_count() returns a count of the number of public key
19       methods available: it includes standard methods and any methods added
20       by the application.
21
22       EVP_PKEY_meth_get0() returns the public key method idx. The value of
23       idx must be between zero and EVP_PKEY_meth_get_count() - 1.
24
25       EVP_PKEY_meth_get0_info() returns the public key ID (a NID) and any
26       flags associated with the public key method *meth.
27

RETURN VALUES

29       EVP_PKEY_meth_count() returns the number of available public key
30       methods.
31
32       EVP_PKEY_meth_get0() return a public key method or NULL if idx is out
33       of range.
34
35       EVP_PKEY_meth_get0_info() does not return a value.
