Fun Fact
Modern browsers use the same cryptographic primitives for random number generation that underpin HTTPS encryption.
Historical Context
Early random string generators relied on predictable pseudo-random algorithms. With the introduction of the Web Cryptography API, browsers gained access to operating-system-level entropy, making client-side random generation both practical and secure.
