Functions |
void | sha1Process (sha1Param *sp) |
| This function performs the core of the SHA-1 hash algorithm; it processes a block of 64 bytes.
|
int | sha1Reset (sha1Param *sp) |
| This function resets the parameter block so that it's ready for a new hash.
|
int | sha1Update (sha1Param *sp, const byte *data, size_t size) |
| This function should be used to pass successive blocks of data to be hashed.
|
int | sha1Digest (sha1Param *sp, byte *digest) |
| This function finishes the current hash computation and copies the digest value into digest.
|
