◆ VerifyProductInformation()

int ArchiveReader::VerifyProductInformation	(	const char *	MARChannelID,
		const char *	appVersion
	)

Verifies that the MAR file matches the current product, channel, and version.

Parameters

MARChannelID	The MAR channel name to use, only updates from MARs with a matching MAR channel name will succeed. If an empty string is passed, no check will be done for the channel name in the product information block. If a comma separated list of values is passed then one value must match.
appVersion	The application version to use, only MARs with an application version >= to appVersion will be applied.

Returns: OK on success COULD_NOT_READ_PRODUCT_INFO_BLOCK if the product info block could not be read. MARCHANNEL_MISMATCH_ERROR if update-settings.ini's MAR channel ID doesn't match the MAR file's MAR channel ID. VERSION_DOWNGRADE_ERROR if the application version for this updater is newer than the one in the MAR.

◆ VerifySignature()

int ArchiveReader::VerifySignature ( )

Performs a verification on the opened MAR file.

Both the primary and backup keys stored are stored in the current process and at least the primary key will be tried. Success will be returned as long as one of the two signatures verify.

Returns: OK on success
