EVP_PKEY2PKCS8 —
convert between EVP_PKEY and PKCS#8
PrivateKeyInfo
SYNOPSIS
#include
<openssl/x509.h>
EVP_PKEY *
EVP_PKCS82PKEY(const
PKCS8_PRIV_KEY_INFO *keyinfo);
PKCS8_PRIV_KEY_INFO *
EVP_PKEY2PKCS8(EVP_PKEY
*pkey);
DESCRIPTION
EVP_PKCS82PKEY()
extracts the private key from a PKCS#8 PrivateKeyInfo
structure.
EVP_PKEY2PKCS8()
creates a PKCS#8 PrivateKeyInfo structure representing
the private key contained in pkey.
Supported algorithms include DH, DSA, EC, GOST2001, and RSA. Application programs can add additional algorithms using EVP_PKEY_asn1_add0(3).
RETURN VALUES
These functions return a newly allocated object or
NULL if the algorithm indicated in
keyinfo or pkey is unsupported
or if memory allocation, decoding, or encoding fails.
