ENCRYPTION AND DECRYPTION

Encrypt text with AES-GCM

Protect a text message with password-based AES-GCM-256 encryption, or decrypt a compatible PXE1 message. Generate a random password in the same tool.

Encryption and decryption run in your browser. Keep your password: an encrypted message cannot be opened without it.

Full mode is enabled. Configure the length and composition of the generated password.

PASSWORD

Key for encryption

The password is case and space sensitive. To decrypt, use the same password.

Password generator settingsLength and character set

Similar symbols 0/O and 1/I are excluded. The password contains at least one character from each selected set.

Save the password. Without it, the encrypted text cannot be recovered. To decrypt, copy the entire result with the prefix PXE1..

Enter the text and select an action.

No result has been created yet.

Text Encryption AES-GCM-256

The encrypted container contains a random salt, nonce and authentication data. A modified result or an incorrect password does not return partial plaintext.

  • Encryption: AES‑GCM‑256 with key derivation from password via PBKDF2-HMAC-SHA-256.
  • Decrypt: recovery of text from a full PXE1 container if the original password is available.
  • Password generator: cryptographically random passwords of length 12–128 characters.
  • Support for Unicode: Russian, English, other languages and Unicode symbols in one message.
  • Local processing: encryption and decryption are performed by the browser on the device.

If you lose your password, it is impossible to decrypt the container. Keep the password separate from the ciphertext file.

HELP

How to encrypt text

Encrypt: Enter a message, set a password or create a random one and click “Encrypt text”. Save both the result and the password.

Decrypt: insert a full text container with the prefix PXE1., specify old password and click “Decrypt text”.

Password generator: In full mode, you can set the length from 12 to 128 characters and select character sets. In simplified mode, 24 characters, letters and numbers are used.

Encryption and decryption are performed in the browser. A lost password cannot be recovered.
