sha1Digest()

int sha1Digest	(	sha1Param *	sp,
		byte *	digest )

This function finishes the current hash computation and copies the digest value into digest.

Parameters

sp	The hash function's parameter block.
digest	The place to store the 20-byte digest.

Return values

0	on success.

sha1Process()

void sha1Process

(

sha1Param *

sp

)
