Hash functions Hash functions are another way cryptography can secure information. But instead of using keys, it relies on algorithms to turn any data input into a fixed-length string of characters.

Caesar cipher is a very simple encryption method and is easily cracked if one studies the frequency of repeating letters. To improve the strength of the encryption method a more complex key could ...

Secret code or foreign language? For machines, it might not matter. Without any prior knowledge, artificial intelligence algorithms have cracked two classic forms of encryption: the Caesar cipher ...
