Checksum - Function Summary
Returns a CRC or other type of checksum.
data - Data to checksum (must be: any-string)
/tcp - Returns an Internet TCP 16-bit checksum.
/secure - Returns a cryptographically secure checksum.
/hash - Returns a hash value
size - Size of the hash table (must be: integer)
/method - Method to use
word - Method: SHA1 MD5 (must be: word)
/key - Returns keyed HMAC value
key-value - Key to use (must be: any-string)
Generally, a checksum is a number which accompanies data to verify that the data has not changed (did not have errors).
The /Secure refinement creates a binary string result that is cryptographically secure:
The /TCP refinement is used to compute the standard TCP networking checksum. This is a weak but fast checksum method.

Not sure of all the /methods but I know there is 'md5 method type for MD5 algorithm
