What is Text Encrypt/Decrypt?

AES-GCM (Advanced Encryption Standard in Galois/Counter Mode) is an authenticated symmetric key algorithm providing encryption, integrity, and authenticity verification.

Protect text payloads securely. Uses PBKDF2 with 100,000 iterations to derive a secure 256-bit AES key from your password, then encrypts with AES-GCM.

How to use the Text Encrypt/Decrypt

  1. 1Choose Mode: Encrypt or Decrypt.
  2. 2Type your secret payload and enter a strong password.
  3. 3Review the secure cipher output block.
  4. 4To decrypt, paste the cipher block, enter the password, and retrieve original text.

Benefits & Key Features

  • Cryptographically secure: AES-GCM 256-bit.
  • Derives key via PBKDF2 with SHA-256 and salt.
  • 100% private: key derivation and encryption happen in browser memory.
