STATIC BOOLEAN ConvertAsn1TimeToEfiTime	(	IN UINT8 *	Ptr,
		OUT EFI_TIME *	EfiTime
	)

Convert ASN.1 GeneralizedTime to EFI Time.

Parameters

[in]	Ptr	Pointer to the ASN.1 GeneralizedTime to be converted.
[out]	EfiTime	Return the corresponding EFI Time.

Return values

TRUE	The time conversion succeeds.
FALSE	Invalid parameters.

BOOLEAN EFIAPI ImageTimestampVerify	(	IN CONST UINT8 *	AuthData,
		IN UINTN	DataSize,
		IN CONST UINT8 *	TsaCert,
		IN UINTN	CertSize,
		OUT EFI_TIME *	SigningTime
	)

Verifies the validity of a RFC3161 Timestamp CounterSignature embedded in PE/COFF Authenticode signature.

Return FALSE to indicate this interface is not supported.

Parameters

[in]	AuthData	Pointer to the Authenticode Signature retrieved from signed PE/COFF image to be verified.
[in]	DataSize	Size of the Authenticode Signature in bytes.
[in]	TsaCert	Pointer to a trusted/root TSA certificate encoded in DER, which is used for TSA certificate chain verification.
[in]	CertSize	Size of the trusted certificate in bytes.
[out]	SigningTime	Return the time of timestamp generation time if the timestamp signature is valid.

Return values

FALSE This interface is not supported.
