CertTimestampAuthenticodeLicense Function

Time-stamps an Authenticode XrML license.

Syntax

HRESULT CertTimestampAuthenticodeLicense (
    [in]  PCRYPT_DATA_BLOB   pSignedLicenseBlob,
    [in]  LPCWSTR            pwszTimestampURI,
    [out] PCRYPT_DATA_BLOB   pTimestampSignatureBlob
);

Parameters

pSignedLicenseBlob
[in] The signed Authenticode XrML license to be time-stamped. See the CRYPTOAPI_BLOB structure.

pwszTimestampURI
[in] The time-stamp server's URI.

pTimestampSignatureBlob
[out] A pointer to CRYPT_DATA_BLOB to receive the base64-encoded time-stamp signature. It is the caller's responsibility to free pTimestampSignatureBlob->pbData with HepFree() after use. See the CRYPTOAPI_BLOB structure.

Remarks

The time-stamp signature is actually a PKCS #7 SignedData message whose content is the binary form of the SignatureValue from the license's signature. Basically, this acts as a counter-signature of the license.

Return Value

S_OK if the function succeeds. Otherwise, returns an error code.

Requirements

Assembly: clr.dll
