WebCryptographic Hash Function. The hash function is another secure way of encryption. Hashing is the act of generating a number from a string of text. The hash is substantially smaller than the text itself, and is generated by a formula in such a way that it is extremely unlikely that some other text will produce the same hash value. WebI tested some different algorithms, measuring speed and number of collisions.
