Encrypting Text Messages
Objective: Securely encrypt your email message content and/or information in GoogleDocs word processing, or text messages. This works on your Windows, Mac, Linux, Android or iOS devices.
Step 1 — Get Text Encryption (PTE) Tool for Your Device
- Get the iOS (iPad/iPhone) version of PTE
- Get the Android version of PTE (built-into SSE)
- Get the Mac/Windows/Linux version of PTE
Encrypting text is pretty easy. You can type it up in a word processor, email window, or text editor, then copy-n-paste it into the PTE window (the top one, as shown below, with decrypted text).
Tip: You wouldn’t want to type up your secret to-be-encrypted text in any cloud service since it’s automatically saved on cloud servers. This is true for Evernote, Gmail, GoogleDrive, etc.
Step 2 — Launch PTE and begin Encryption Process
To accomplish the encryption, click on ENCRYPT and you’ll get the encrypted text. Note that although there are various choices for encryption algorithm, I’m going to use AES (256 bit) for the purposes of this example.
Copy-n-paste the encrypted text where you want it to go, such as an email window or a word processor file (e.g. GoogleDocs, LibreOffice, MS Word):
To decrypt, open up your text where you saved your work (for example, here’s what the web version of Evernote looks like) and paste it in:
To decrypt, paste your encrypted text in the bottom half of the PTE window then, after entering your top secret password, click DECRYPT button:
Note: that throughout this, I’ve chosen to “show” my password. You can actually choose to “hide” the password and it’s gone when you quit PTE.
If you are on an iOS device, here’s what it looks like decrypting:
a) Open up PTE on your iOS device. You’ll be prompted for a password, so enter the one you used to encrypt text earlier:
Click SET and PTE is ready to go (it will go to the more familiar split screen for encrypting/decrypting text)
b) Copy-n-paste text from your Evernote app windows, as shown below:
c) Paste encrypted text into the bottom window, then tap on the Decrypt button. That will show you the decrypted text in the top window.
This process looks a bit different on Android…here’s an older screenshot:

The Android version also includes a Password Vault, as well as the SSE feature. I have encrypted files on my computer, transferred them to my phone for portability, decrypted them on my phone, and vice versa. The ability to do that provides another layer of security for mobile devices.
