SYNOPSIS

13
14        const OSSL_PARAM *EVP_PKEY_settable_params(const EVP_PKEY *pkey);
15        int EVP_PKEY_set_params(EVP_PKEY *pkey, OSSL_PARAM params[]);
16        int EVP_PKEY_set_int_param(EVP_PKEY *pkey, const char *key_name, int in);
17        int EVP_PKEY_set_size_t_param(EVP_PKEY *pkey, const char *key_name, size_t in);

20        int EVP_PKEY_set_utf8_string_param(EVP_PKEY *pkey, const char *key_name,
21                                           const char *str);
22        int EVP_PKEY_set_octet_string_param(EVP_PKEY *pkey, const char *key_name,

DESCRIPTION

26       These functions can be used to set additional parameters into an
27       existing EVP_PKEY.
28
29       EVP_PKEY_set_params() sets one or more params into a pkey.  See
30       OSSL_PARAM(3) for information about parameters.
31
32       EVP_PKEY_settable_params() returns a constant list of params indicating
33       the names and types of key parameters that can be set.  See
34       OSSL_PARAM(3) for information about parameters.
35
36       EVP_PKEY_set_int_param() sets an integer value in into a key pkey for
37       the associated field key_name.
38
39       EVP_PKEY_set_size_t_param() sets an size_t value in into a key pkey for
40       the associated field key_name.
41
42       EVP_PKEY_set_bn_param() sets the BIGNUM value bn into a key pkey for
43       the associated field key_name.
44
45       EVP_PKEY_set_utf8_string_param() sets the UTF8 string str into a key
46       pkey for the associated field key_name.
47
48       EVP_PKEY_set_octet_string_param() sets the octet string value buf with
49       a size bsize into a key pkey for the associated field key_name.

NOTES

52       These functions only work for EVP_PKEYs that contain a provider side
53       key.
54

RETURN VALUES

56       EVP_PKEY_settable_params() returns NULL on error or if it is not
57       supported,
58
59       All other methods return 1 if a value was successfully set, or 0 if
60       there was an error.
