Detailed Description

Compute a SHA-256 message digest.

This class provides an interface to compute a digest in a "streaming" manner (the message can be split into chunks which are processed sequentially) as well as a convenient interface which allows one to create a digest in a single step.

Member Function Documentation

void CS::Utility::Checksum::SHA256::Append	(	const uint8 *	input,
		size_t	length
	)

Used to update the the input data hash.

Parameters:

	input	A pointer to an array of the input data with which to update the hash.
	length	The length of the input data to hash (in bytes).

static Digest CS::Utility::Checksum::SHA256::Encode	(	const void *	,
		size_t	nbytes
	)			[static]

Encode a buffer.

static Digest CS::Utility::Checksum::SHA256::Encode

(

const char *

)

[static]

Encode a null-terminated string buffer.

static Digest CS::Utility::Checksum::SHA256::Encode

(

csString const &

)

[static]

Encode a string.

Digest CS::Utility::Checksum::SHA256::Finish

(

)

Used to complete the hashing process and obtain the calculated hash.

After finishing, don't append further data to the hash -- the resulting digest will be bogus.

Returns:

The calculated hash.
