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.
