Weaknesses (CWE)
CWE-338 — Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG): The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong.
- [Implementation] Use functions or hardware which use a hardware-based random number generation for all crypto. This is the recommended solution. Use CyptGenRandom on Windows, or hw_rand() on Linux.
