Online encryption
Hash text with SHA algorithms or encrypt/decrypt with AES-GCM in your browser.
Input
Output
Hashing and AES use the Web Crypto API in your browser. Do not encrypt highly sensitive production secrets here without understanding the risks.
What it does
- Hash — SHA-1, SHA-256, SHA-384, SHA-512 (hex output).
- AES-GCM — passphrase-based encrypt/decrypt with a portable JSON payload.
Security
This is a convenience utility, not a certified crypto product. Do not rely on it for high-risk secrets without expert review.
