EVP_PKEY_settable_params3ssl

Usage

 #include <openssl/evp.h>
 const OSSL_PARAM *EVP_PKEY_settable_params(const EVP_PKEY *pkey);
 int EVP_PKEY_set_params(EVP_PKEY *pkey, OSSL_PARAM params[]);
 int EVP_PKEY_set_int_param(EVP_PKEY *pkey, const char *key_name, int in);
 int EVP_PKEY_set_size_t_param(EVP_PKEY *pkey, const char *key_name, size_t in);
 int EVP_PKEY_set_bn_param(EVP_PKEY *pkey, const char *key_name,
                           const BIGNUM *bn);
 int EVP_PKEY_set_utf8_string_param(EVP_PKEY *pkey, const char *key_name,
                                    const char *str);
 int EVP_PKEY_set_octet_string_param(EVP_PKEY *pkey, const char *key_name,
                                     const unsigned char *buf, size_t bsize);

Overview

These functions can be used to set additional parameters into an existing EVP_PKEY.

EVP_PKEY_set_params() sets one or more params into a pkey. See OSSL_PARAM(3) for information about parameters.

EVP_PKEY_settable_params() returns a constant list of params indicating the names and types of key parameters that can be set. See OSSL_PARAM(3) for information about parameters.

EVP_PKEY_set_int_param() sets an integer value in into a key pkey for the associated field key_name.

EVP_PKEY_set_size_t_param() sets an size_t value in into a key pkey for the associated field key_name.

EVP_PKEY_set_bn_param() sets the BIGNUM value bn into a key pkey for the associated field key_name.

EVP_PKEY_set_utf8_string_param() sets the UTF8 string str into a key pkey for the associated field key_name.

EVP_PKEY_set_octet_string_param() sets the octet string value buf with a size bsize into a key pkey for the associated field key_name.

Notes

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

Return values

EVP_PKEY_settable_params() returns NULL on error or if it is not supported,

All other methods return 1 if a value was successfully set, or 0 if there was an error.
