Cryptographically secured hash function

WebBoth ideas are safe if the hash function behaves like a random oracle and has a large enough output (in particular for "idea 1": with a function which outputs n bits at a time, it is expected that the state will enter a cycle of length about 2n/2, after about 2n/2 steps, so if you want "128-bit security", you will need n = 256 or more). Weboutput. The hash function is a one-way function, i.e. it is very hard to guess its input if only the output is given. Examples of cryptographically strong hash functions are MD5 [12] or SHA-1 [13]. When the license is first created, a random string t 0 is generated. The hash function h is the applied n times recursively t i+1 = h(t i)
