Csprng seed
WebApr 13, 2016 · CSPRNG s have certain properties that make them suitable for use in security: Every CSPRNG should satisfy the next-bit test. That is, given the first k bits of a random sequence, there is no polynomial-time algorithm that can predict the (k+1)th bit with probability of success better than 50%. WebAlso, don't attempt to seed the RNG manually. Java's default behavior is to read from the OS's CSPRNG. Furthermore, never call SecureRandom.generateSeed(), which on some platforms always uses /dev/random instead of /dev/urandom which kills your app's performance. Cryptographically Secure Randomness in JavaScript (Client-Side, In …
