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();

Parameter	Description
Returns	A hexadecimal hash sum

hashReset

Resets the digest for further use.

void hashReset();

Parameter	Description
Returns	Nothing

hashUpdate

Updates the digest using the specified array of bytes.

void hashUpdate(bytearray);

Parameter	Description
`bytearray`	Any type of bytearray
Returns	Nothing

hashSetAlgorithm

Uses a digest that implements the specified digest algorithm.

Note!

The default setting, that is if the algorithm is not set, the SHA-1 hash method is used.

void hashSetAlgorithm(<"hash_method">);

Parameter	Description
`<"hash_method">`	The name of the algorithm requested. Supported hash algorithms are: MD2, MD5, SHA-1, SHA-256, SHA-384, SHA-512
Returns	Nothing.

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);

Parameter	Description
`<"unique_hash">`	The name of the hash algorithm developed by the provider
`Provider`	The name of the provider
Returns	Nothing

Hash Example

Example - Hash

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);
}
