Text Encryption
Encrypt and decrypt text securely using AES-256-GCM encryption in your browser.
About Text Encryption
Text Encryption is a free online tool that lets you encrypt and decrypt text using AES-256-GCM, one of the strongest encryption standards available. It uses PBKDF2 key derivation with 100,000 iterations for maximum security. All processing happens entirely in your browser — your data and password never leave your device.
How to Use
Select Encrypt or Decrypt mode. To encrypt, enter your text and a strong password, then click Process. The encrypted output is a Base64 string you can safely share. To decrypt, paste the encrypted string, enter the same password, and click Process. The password strength indicator helps you choose a secure password.
