Data Structures

struct  sha256Param
 Holds all the parameters necessary for the SHA-256 algorithm. More...


Functions

void sha256Process (sha256Param *sp)
 This function performs the core of the SHA-256 hash algorithm; it processes a block of 64 bytes.

int sha256Reset (sha256Param *sp)
 This function resets the parameter block so that it's ready for a new hash.

int sha256Update (sha256Param *sp, const byte *data, size_t size)
 This function should be used to pass successive blocks of data to be hashed.

int sha256Digest (sha256Param *sp, byte *digest)
 This function finishes the current hash computation and copies the digest value into digest.


Variables

const hashFunction sha256
 Holds the full API description of the SHA-256 algorithm.
