CRYPT_PRIVATE_KEY_INFO structure (wincrypt.h)
[The CRYPT_PRIVATE_KEY_INFO structure is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]
The CRYPT_PRIVATE_KEY_INFO structure contains a clear-text private key in the PrivateKey field (DER encoded). CRYPT_PRIVATE_KEY_INFO contains the information in a PKCS #8 PrivateKeyInfo ASN.1 type found in the PKCS #8 standard.
Syntax
typedef struct _CRYPT_PRIVATE_KEY_INFO {
DWORD Version;
