Safe Client-Side Hashing & UUID Generation
UUIDs (Universally Unique Identifiers), specifically version 4, are 128-bit numbers generated using high-quality pseudorandom algorithms. They are widely implemented in database schemas, primary keys, session tracking, and transaction IDs to ensure uniqueness across distributed systems without needing central coordination.
Cryptographic hashes (such as SHA-256 and MD5) act as unique digital signatures for strings or messages. Because this generator is powered entirely by the native browser Web Cryptography API (`crypto.subtle`), no data is sent to external servers. This keeps your API payloads, credentials, and text segments completely private.
