數位憑證結構

CERT_CONTEXT結構

typedef struct _CERT_CONTEXT { DWORD dwCertEncodingType;  BYTE* pbCertEncoded;  DWORD cbCertEncoded; PCERT_INFO pCertInfo;  HCERTSTORE hCertStore;} CERT_CONTEXT,  *PCERT_CONTEXT;typedef const CERT_CONTEXT *PCCERT_CONTEXT;

參數dwCertEncodingType一般有倆值：

Value	Meaning
PKCS_7_ASN_ENCODING 65536 0x10000	Specifies PKCS 7 message encoding.
X509_ASN_ENCODING 1 0x1	Specifies X.509 certificate encoding.

參數pbCertEncoded，指向編碼認證的指標

參數cbCertEncoded，編碼認證的大小，單位BYTE

參數pCertInfo：Pointer to a structure of certificate information.

hCertStore：Handle to the certificate store that contains the certificate context. 

CERT_INFO 的資料結構

typedef struct _CERT_INFO {  DWORD dwVersion;  CRYPT_INTEGER_BLOB SerialNumber;  CRYPT_ALGORITHM_IDENTIFIER SignatureAlgorithm;  CERT_NAME_BLOB Issuer;  FILETIME NotBefore;  FILETIME NotAfter;  CERT_NAME_BLOB Subject;  CERT_PUBLIC_KEY_INFO SubjectPublicKeyInfo;  CRYPT_BIT_BLOB IssuerUniqueId;  CRYPT_BIT_BLOB SubjectUniqueId;  DWORD cExtension;  PCERT_EXTENSION rgExtension;} CERT_INFO,  *PCERT_INFO;
