A cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the (cryptographic) hash value, such that an accidental or intentional change to the data will change the hash value. The data to be encoded is often called the "message", and the hash value is sometimes called the message digest or simply digest.
From Wikipedia.
Message digest/check sum is, I would suppose, a cryptographic hash function. To encode a block of text in it, go here:

Also has tools for encoding/decoding in binary, hexadecimal, base 64, and decimal.
