CERT_CONTEXT

The CERT_CONTEXT structure contains both the encoded and decoded representations of a certificate. A certificate context returned by one of the functions defined in Wincrypt.h must be freed by calling the CertFreeCertificateContext function. The CertDuplicateCertificateContext function can be called to make a duplicate copy (which also must be freed by calling CertFreeCertificateContext).

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;
 

Members

dwCertEncodingType

The type of encoding used on the certificate. Currently defined certificate encoding types are shown in the following table:

Encoding type	Value
X509_ASN_ENCODING	0x00000001

pbCertEncoded

A pointer to the encoded certificate.

cbCertEncoded

The size, in bytes, of the encoded certificate.

pCertInfo

A pointer to a structure of certificate information.

hCertStore

A handle to the certificate store that contains the certificate context.
