template<unsigned int N>

static Digest<N> Digest< N >::asDigest	(	const byte *	d,
		const unsigned int	len
	)			[inline, static]

Pseudo-constructor to create a digest from a byte array.

NOTE! This is NOT a message digest OF the byte array; rather we interpreting the bytes in the array as a message digest itself. This might be the case if e.g. a bunch of message digests have been saved to disk as byte images.

Image<byte> Digest< N >::asImage

(

)

const [inline]

Return an Nx1 Image containing the digest.

template<unsigned int N>

std::string Digest< N >::asString

(

)

const [inline]

Return a string with N*2 hexadecimal chars representing the digest.

template<unsigned int N>

static Digest<N> Digest< N >::fromString

(

const std::string &

s

)

[inline, static]

Generate a digest by parsing hex digits from a string.

Parameters:

s

digest string must have exactly 2*N characters, each of which must be a valid hex digit (0-9, a-f, A-F)
