Constructor & Destructor Documentation

ZStreamW_SHA1::ZStreamW_SHA1	(	uint8	oDigest[20],
		const ZStreamW &	iStreamSink
	)

Constructor for use inline.

This constructor remembers the address of oDigest, and when destroyed will place the digest in that array. This constructor is useful when a ZStreamW is already being used to write some data, but for which we would like to gather a digest. e.g. going from this:

destStream.Write(source, sourceSize);

to this:

uint8 theDigest[20];
ZStreamW_SHA1(theDigest, destStream).Write(source, sourceSize);

It can also be used to simply digest a block of data in memory, by passing a temporary ZStreamW_Null as the destination stream:

uint8 theDigest[20];
ZStreamW_SHA1(theDigest, ZStreamW_Null()).Write(source, sourceSize);
