You need to send a password, a recovery phrase or a private note through a channel you don't fully trust. Encrypt it first. What you send is a block of letters and digits that means nothing without the password.
The text is locked with AES-256 in GCM mode, and the key comes from your password through 250,000 rounds of PBKDF2. It all happens in your browser. Send the locked text one way and tell the other person the password another way, by phone for example.
How to use the Encrypt and Decrypt Text tool
- Type or paste the text, and choose a password.
- Press Encrypt and send the result.
- To read it, paste the locked text, enter the password and press Decrypt.
Popular uses
- Sending login details or keys by email or chat
- Storing private notes in a cloud document
- Passing a message through someone who should not read it
Tips for the best result
- The strength is in the password. Four or five random words beat a short complicated one.
- There is no recovery. Forget the password and the text is gone.
