Websignatures of all post quantum candidates. Hash-based solutions use a pseudo-random function to turn any size input into an encrypted, specific size output. Hash functions are also called one-way functions as they are not easily (i.e. computationally complex) computed in reverse. This is what makes them very useful in

WebIt is also believed that the effort of finding a pre-image of a hash function is n/2, where n is the output size of the hash. Thus, to have quantum security equivalent to classical 128-bit security level, we would need at least 256-bit hash functions.
