Your data stays private. All encryption and decryption happens entirely in your browser using the Web Crypto API (AES-256-GCM with PBKDF2 key derivation). No data is ever sent to a server.
AES-GCM encryption with password-based key derivation
This free online tool lets you encrypt and decrypt any text using AES-256-GCM, one of the strongest symmetric encryption standards available. You provide a password, and the tool uses PBKDF2 with 600,000 iterations to derive a cryptographic key, ensuring your data is protected against brute-force attacks. The encrypted output is Base64-encoded for easy sharing and storage.
All encryption and decryption happens entirely in your browser using the Web Crypto API. No data is ever transmitted to a server, making this tool safe for sensitive information such as passwords, private notes, or confidential messages. Simply paste your text, enter a strong password, and click Encrypt or Decrypt.
This tool is useful for journalists, developers, privacy-conscious users, and anyone who needs a quick, reliable way to protect text data without installing software or trusting a third-party service.
