Use the functions below to turn bytearray input of arbitrary length into an output of fixed length

hashDigest

Completes the hash computation by performing final operations such as padding. After this call is made the digest is reset.

bytearray hashDigest();

hashReset

Resets the digest for further use.

void hashReset();

hashUpdate

Updates the digest using the specified array of bytes.

void hashUpdate(bytearray);

hashSetAlgorithm

Uses a digest that implements the specified digest algorithm.

void hashSetAlgorithm(<"hash_method">);

hashSetAlgorithmFromProvider

Uses a digest that implements the specified digest algorithm, as supplied from the specified provider. The digest will be reset.

void hashSetAlgorithmFromProvider(string,string);

Hash Example

initialize {
 hashSetAlgorithm("MD2");
}
 
beginBatch {
 hashReset();
}
 
consume {
 hashUpdate(input); 
}
 
drain {
 bytearray hashsum = hashDigest();
 string sHashSum = baToHexString(hashsum); // Optional
 bytearray result; // Optional
 strToBA(result, sHashSum); // Optional
 udrRoute(result);
}
