EVP_PKEY2PKCS83ssl

Usage

 #include <openssl/x509.h>
 PKCS8_PRIV_KEY_INFO *EVP_PKEY2PKCS8(const EVP_PKEY *pkey);
 EVP_PKEY *EVP_PKCS82PKEY(const PKCS8_PRIV_KEY_INFO *p8);
 EVP_PKEY *EVP_PKCS82PKEY_ex(const PKCS8_PRIV_KEY_INFO *p8, OSSL_LIB_CTX *libctx,
                             const char *propq);

Overview

EVP_PKEY2PKCS8() converts a private key pkey into a returned PKCS8 object.

EVP_PKCS82PKEY_ex() converts a PKCS8 object p8 into a returned private key. It uses libctx and propq when fetching algorithms.

EVP_PKCS82PKEY() is similar to EVP_PKCS82PKEY_ex() but uses default values of NULL for the libctx and propq.

Return values

EVP_PKEY2PKCS8() returns a PKCS8 object on success. EVP_PKCS82PKEY() and EVP_PKCS82PKEY_ex() return a private key on success.

All functions return NULL if the operation fails.
