Encrypt/decrypt Message

Encrypt or decrypt text using a passphrase. The same passphrase used for encryption must be used again to decrypt the message.

How it works

Choose Encrypt or Decrypt mode.
Enter a passphrase (this acts as the encryption key)
Paste or type your message. The result is generated instantly.

To decrypt a message, you must use the same passphrase that was used to encrypt it. If the passphrase is incorrect, the message cannot be recovered.

Text to Encrypt

Provide the text message to encrypt.

All encryption/decryption happen locally in your browser. Your text and passphrase are never sent to a server.
