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) WebIt seems that sha256 is becoming more and more used in order to replace the old md5 hash function.
