TXTcrypt For Mac

TXTcrypt is a very simple macOS application that is capable of encrypting plain text to a series of characters and decrypting it. TXTcryptJ works by entering the text you want to encrypt, specifying a password and clicking on the Encrypt button.

After clicking on Encrypt, the encrypted code (which you can copy to your clipboard) will be displayed in the app’s notepad.

You can send this code along with the password to another user with a Mac that has TXTcrypt installed, and he / she will have easily received an encrypted message.

TXTcrypt is not recommended for encrypting very important information, but mainly for SMS messages, e-mails, private notes etc. The encryption type is RC4 with support for keys of up to 64 bit (the value depends on your password’s length).

TXTcrypt also includes an indicator of your password’s strength that turns red if the password is too weak, yellow if it’s average and green if it’s strong enough not to be guessed with ease.

An additional feature is that the app displays the number of characters (entered in the app’s notepad) on the TXTcrypt dock icon. This behavior is similar to how Mail shows the number of unread email messages on its dock icon.

To conclude, TXTcrypt does not provide the safest way of encrypting text and is probably not the best encryption tool for OS X, but it’s free, very easy-to-use and can serve the general purpose of encrypting messages of moderate importance.
