Both tools on this page run entirely in your browser's secure cryptographic context. The Web Crypto API is the same engine your browser uses for HTTPS. No data is sent anywhere. No input is stored. Paste passwords, secrets, and sensitive data safely — we have no way of seeing it.
HASH GENERATOR
Generate SHA-1, SHA-256, SHA-384, and SHA-512 hashes via Web Crypto API. Click any result to copy. Nothing transmitted.

AES-256 Encryption
AES-256 ENCRYPTION
Encrypt and decrypt text using AES-256-GCM. PBKDF2 key derivation with 100,000 iterations. Everything runs locally. Your data never leaves this device.
● AES-256-GCM
🔑
Military-grade encryption in your browser. AES-256-GCM with PBKDF2 key derivation. The encrypted output is mathematically meaningless without your passphrase. No server. No storage. We never see your data or your passphrase.
Passphrase
Input — plain text or encrypted Base64
Output
Algorithm: AES-256-GCM Key derivation: PBKDF2 Iterations: 100,000 Salt: Random 128-bit IV: Random 96-bit
