CSPRNG
A cryptographically secure pseudo-random number generator seeded from the kernel entropy pool, designed so that internal state cannot be inferred from its output even when the algorithm is public, ensuring unpredictability and making it suitable for security-sensitive scenarios.
Timeline (last 90 days)
A cryptographically secure pseudorandom number generator (CSPRNG) must satisfy two conditions: statistical randomness and unpredictability; common implementations include /dev/urandom and CryptGenRandom, which collect randomness from hardware entropy sources.
The core difference between a CSPRNG and an ordinary PRNG is that even if an attacker knows part of the output sequence, it is computationally infeasible to derive subsequent outputs or the internal state.
For scenarios that truly require security, cryptographically validated schemes (such as CSPRNGs) should be used, rather than relying on security through obscurity.
