Outil de cryptage et de décryptage de texte gratuit
AES-256-GCM encryption, 100% in your browser.
Uses AES-256-GCM via the Web Crypto API. A random 96-bit IV and 128-bit salt are generated per encryption. The password is derived with PBKDF2 (100 000 iterations, SHA-256).
How to Use
- Choose Encrypt or Decrypt mode.
- Enter your text and a password.
- Click the action button · the result appears below.
- To decrypt, paste the encrypted output and use the same password.
Frequently Asked Questions
Is this encryption secure?
Yes. AES-256-GCM is a military-grade cipher. Combined with PBKDF2 key derivation (100k iterations), it offers strong protection. However, security depends on your password strength.
Can you recover my password?
No. Everything runs in your browser. We never see your text or password. If you lose your password, the encrypted text cannot be recovered.
What format is the output?
The encrypted output is a Base64 string that contains the salt, IV, and ciphertext. Simply paste it back into the tool to decrypt.
