This bean computes hash function value of its input data. Any hash function takes an arbitrary-sized array of data
as an input, and generates a fixed-sized output, called a hash (digest). Safe and reliable hash functions satisfy the
2 following requirements:
- it is computationally infeasible to find two messages that have the same hash value;
- the hash value of the message doesn't allow to derive any information about the message itself.
That is why message digests can be used to identify the data. The data integrity may be checked by comparing
the current message hash value with the original value.
