How it works
Hashing uses the browser's native Web Crypto API (crypto.subtle.digest).
Common use cases
- Checking data integrity
- Generating checksums
- Learning about cryptographic hashing
Frequently asked questions
- Is hashing the same as encryption?
- No. Hashing is one-way and cannot be reversed to recover the original text; encryption is reversible with a key.
