Functions

void sha512Process (sha512Param *sp)
 This function performs the core of the SHA-512 hash algorithm; it processes a block of 128 bytes.
int sha512Reset (sha512Param *sp)
 This function resets the parameter block so that it's ready for a new hash.
int sha512Update (sha512Param *sp, const byte *data, size_t size)
 This function should be used to pass successive blocks of data to be hashed.
int sha512Digest (sha512Param *sp, byte *digest)
 This function finishes the current hash computation and copies the digest value into digest.

int sha512Reset ( sha512Param sp  ) 

This function resets the parameter block so that it's ready for a new hash.

Parameters:
sp The hash function's parameter block.
Return values:
0 on success.
int sha512Update ( sha512Param sp,
const byte data,
size_t  size 
)

This function should be used to pass successive blocks of data to be hashed.

Parameters:
sp The hash function's parameter block.
data 
size 
Return values:
0 on success.
