Why do two similar strings produce very different hashes?
Secure hash functions are designed so tiny input changes produce very different output.

Generate cryptographic hashes from text using the Web Crypto API.
Hashing Use Cases
Hash functions help with integrity checks, quick fingerprints, and cache keys. They are one-way transforms, not reversible storage.
- Compare hash output to detect accidental file or text changes.
- Pick a modern algorithm such as SHA-256 for general integrity checks.
- Keep normalization consistent before hashing to avoid false mismatches.

Hash Generator FAQ
Can I recover original text from a hash?
No. Hashes are one-way values and cannot be directly reversed.
Should I hash files and text the same way?
Only if the exact byte representation is identical. Encoding differences change the hash.
