Detailed Description

SHA1 CUDA hash function support.

This file is based on Brad Conte's basic implementations of cryptography algorithms...

Function Documentation

cu_sha1()

__device__ void cu_sha1	(	const void *	in,
		size_t	inlen,
		void *	out
	)

Convenient all-in-one SHA1 computation.

Performs cu_sha1_init(), cu_sha1_update() and cu_sha1_final(), and places the resulting hash in out.

Parameters

in	Pointer to data to hash
inlen	Length of in data, in bytes
out	Pointer to location to place the message digest

cu_sha1_final()

__device__ void cu_sha1_final	(	SHA1_CTX *	ctx,
		void *	out
	)

Finalize a SHA1 message digest.

Generate the SHA1 message digest and place in out.

Parameters

ctx	Pointer to SHA1 context
out	Pointer to location to place the message digest

cu_sha1_init()

__device__ void cu_sha1_init

(

SHA1_CTX *

ctx

)

Initialize a SHA1 context.

Parameters

ctx	Pointer to SHA1 context

cu_sha1_transform()

__device__ void cu_sha1_transform	(	SHA1_CTX *	ctx,
		const uint8_t	data[]
	)

SHA1 transformation rounds.

Parameters

ctx	Pointer to SHA1 context
data	Pointer to input to be transformed

SHA1 transformation constant.

cu_sha1_update()

__device__ void cu_sha1_update	(	SHA1_CTX *	ctx,
		const void *	in,
		size_t	inlen
	)

Add inlen bytes from in to a SHA1 context for hashing.

Parameters

ctx	Pointer to SHA1 context
in	Pointer to data to hash
inlen	Length of in data, in bytes
