Function Documentation

swiSHA1Calc()

void swiSHA1Calc	(	void *	digest,
		const void *	data,
		size_t	len
	)

SHA-1 checksum.

Parameters

digest	Buffer to hold SHA-1 checksum result.
data	Buffer to process.
len	Length of data.

swiSHA1Final()

void swiSHA1Final	(	void *	digest,
		swiSHA1context_t *	ctx
	)

SHA-1 final digest.

Parameters

digest	Buffer to hold SHA-1 checksum result
ctx	SHA-1 context

swiSHA1Init()

void swiSHA1Init

(

swiSHA1context_t *

ctx

)

SHA-1 context setup.

Parameters

ctx	Context to be initialized

swiSHA1Update()

void swiSHA1Update	(	swiSHA1context_t *	ctx,
		const void *	data,
		size_t	len
	)

SHA-1 process buffer.

Parameters

ctx	SHA-1 context.
data	Buffer to process.
len	Length of data.

swiSHA1Verify()

int swiSHA1Verify	(	const void *	digest1,
		const void *	digest2
	)

SHA-1 verify.

Parameters

digest1	Buffer containing hash to verify.
digest2	Buffer containing hash to verify.

Returns

1 if they match, else 0. If either pointer is NULL it returns 0.
