Function Documentation

computeStreamMD5()

bool Common::computeStreamMD5	(	ReadStream &	stream,
		uint8	digest[16],
		uint32	length = 0
	)

Compute the MD5 checksum of the content of the given ReadStream. The 128 bit MD5 checksum is returned directly in the array digest. If length is set to a positive value, then only the first length bytes of the stream are used to compute the checksum.

Parameters

[in]	stream	the stream of whose data the MD5 is computed
[out]	digest	the computed MD5 checksum
[in]	length	the number of bytes for which to compute the checksum; 0 means all

Returns

true on success, false if an error occurred

computeStreamMD5AsString()

String Common::computeStreamMD5AsString	(	ReadStream &	stream,
		uint32	length = 0
	)

Compute the MD5 checksum of the content of the given ReadStream. The 128 bit MD5 checksum is converted to a human readable lowercase hex string of length 32. If length is set to a positive value, then only the first length bytes of the stream are used to compute the checksum.

Parameters

[in]	stream	the stream of whose data the MD5 is computed
[in]	length	the number of bytes for which to compute the checksum; 0 means all

Returns

the MD5 as a hex string on success, and an empty string if an error occurred
