Random Number Generator Library (such as OpenSSL or Python's random module)

A Random Number Generator (RNG) library, like OpenSSL or Python’s random module, is a set of tools that produces unpredictable sequences of numbers. These numbers are used in various applications such as cryptography, simulations, and security. Some RNGs generate numbers based on complex algorithms (pseudo-random), while others use unpredictable physical phenomena (true randomness). Libraries provide functions to generate random values reliably and efficiently, ensuring security and fairness when randomness is essential. They abstract the complexity behind creating these unpredictable numbers, making it easier for developers to implement secure, random data in their programs.
