Sending encrypted messages with Android is very easy: just use an app or web service. Here are the best ones
There are several reasons to send an encrypted message from your Android smartphone. It can be a way to keep your company’s data safe, or to hide from prying eyes a secret you need to confide. But how can we send an encrypted SMS on Android?
Sending an encrypted message on Google OS phone is quite easy. And as luck would have it, there’s more than one method we can put into practice to keep our conversations safe. Let’s start with perhaps the quickest and easiest method, an app. The apps to use for encryption on Android are K-9 Mail and OpenKeychain: Easy PGP. With these two solutions we’ll be able to send emails and messages using encryption. Beware that the two apps are to be used together, in fact, one will be used to send the message while the other will create the encryption key.
Signal
Are you looking for something more practical and that focuses on SMS instead of email? No problem, Signal is for you. Signal is a messaging app similar to WhatsApp. With Signal we can chat with contacts, create groups and even make calls. All protected by encryption. The limitation? The recipient of the message must have Signal installed otherwise it will not display what we have sent. And at the moment the app isn’t as widespread as WhatsApp or Facebook Messenger.
Using CryptMax
If we’re looking for a tool to independently encrypt a message or email, the right choice is the “Encrypt text with CryptMax” service. It’s an app that we easily install and that generates a security key to unlock text encryption. Whoever receives a message must install the service and know the password in order to read it.
Encrypt Easy
Don’t have much space in your phone’s memory or don’t want to install another application? No problem, you can use the Encrypt Easy website directly from your phone’s browser. Using it is very simple. In the text box we have to enter the message we want to send and click on send. The site will return an encrypted text for us to send. Whoever receives the message must go to the site and enter the text received to decrypt it and be able to read it.
