Detailed Description

This class represents the implementation of the sha256 algorithm.

Basically the class provides three public member-functions to create a hash: SHA256_Init(), SHA256_Update() and SHA256_End(). If you want to create a hash based on a string or file quickly you should use the sha256wrapper class instead of SHA256.

char* SHA256::SHA256_End	(	HL_SHA256_CTX *	context,
		char	buffer[SHA256_DIGEST_STRING_LENGTH]
	)

Ends the sha256 operation and return the created hash in the given buffer.

Parameters:

	context	The context to end.
	buffer	This OUT-Parameter contains the created hash after ending the operation.

void SHA256::SHA256_Final	(	hl_uint8	digest[SHA256_DIGEST_LENGTH],
		HL_SHA256_CTX *	context
	)			[private]

Finalize the sha256 operation.

Parameters:

	digest	The digest to finalize the operation with.
	context	The context to finalize.

void SHA256::SHA256_Init

(

HL_SHA256_CTX *

context

)

void SHA256::SHA256_Transform	(	HL_SHA256_CTX *	context,
		const sha2_word32 *	data
	)			[private]

Internal data transformation.

Parameters:

	context	The context to use
	data	The data to transform

void SHA256::SHA256_Update	(	HL_SHA256_CTX *	context,
		const hl_uint8 *	data,
		unsigned int	len
	)

Updates the context.

Parameters:

	context	The context to update.
	data	The data for updating the context.
