php_mt_seed

Solar Designer ❘ Open Source ❘
Mac

php_mt_seed finds possible seeds given the very first PHP mt_rand() output after possible seeding with mt_srand(). With advanced invocation modes, php_mt_seed is also able to match multiple, non-first, and/or inexact mt_rand() outputs to possible seed values. php_mt_seed is written in C with optional SIMD intrinsics (SSE4.1/AVX, XOP, AVX2, MIC) and OpenMP. On a modern quad-core CPU, it is able to search the full 32-bit seed space in one minute (or in just seven seconds on Xeon Phi).

Pros

Fast and efficient performance for generating pseudo-random numbers.
Provides a good quality of randomness for general purposes.
Open-source and freely available for modification and distribution.
Widely recognized and trusted due to its association with Solar Designer, a respected expert in security and cryptography.
Can be used in a variety of applications, including cryptographic contexts when configured properly.

Cons

May not be suitable for all cryptographic uses without additional measures due to potential predictability in some scenarios.
As a pseudo-random number generator (PRNG), it is not truly random, which may be a factor for applications requiring high-stakes security.
Requires proper understanding of seeding and usage to ensure optimal results, which may be a barrier for beginners.
Limited documentation compared to more established libraries, making it harder to find support or examples.
