CWE - CWE-331: Insufficient Entropy (4.10) - Mitre Corporation

WebCryptographically Secure Pseudo-Random Number Generators (CSPRNG) are designed to produce a much higher quality of randomness (more strictly, a greater amount of entropy), making them safe to use for security-sensitive functionality. 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. WebThe product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong.
