WebSince this algorithm aims to generate decimal numbers from a cryptographically strong random byte stream, the distribution of the generated numbers will mostly follow a natural distribution. This means that if you generate a single digit token, you are mostly equally likely to hit any of the decimal numbers 0-9 inclusive. WebIn computer science random numbers usually come from a pseudo-random number generators (PRNG), initialized by some unpredictable initial randomness (entropy). In cryptography secure PRNGs are used, known as CSPRNG, which typically combined entropy with PRNG and other techniques to make the generated randomness unpredictable.
