WebJan 6, 2015 · "PRNG" means "Pseudorandom Number Generator" which means that a sequence of numbers (bits, bytes...) is produced from an algorithm which looks random, but is in fact deterministic (the sequence is generated from some unknown internal state), hence pseudorandom. Such pseudorandomness can be cryptographically secure, or not. WebJun 22, 2015 · Never roll your own RNG or Crypto. Use well-known, tested, mature code, and use it exactly as directed.

The problem with this algorithm is that it’s not cryptographically strong. In other words, the generated values are much more predictable, therefore attackers could use it to compromise our system. inception crm

"WebMany SecureRandom implementations are in the form of a pseudo-random number generator (PRNG), which means they use a deterministic algorithm to produce a pseudo-random sequence from a true random seed. Other implementations may produce true random numbers, and yet others may use a combination of both techniques. " - Cryptographic prng in java
