Chat safely with these encrypted messaging apps

In order for us to be sure that our messages are sent with all the security guarantees, the application must have end-to-end encryption. In this way, we make sure that the service provider does not keep any copies of the messages we send on its server. Thus, only the people with whom we are communicating will have access to the messages.

The importance of an encrypted application

As we have commented, for an instant messaging application to be secure it is necessary to encrypt the messages from end to end. However, you have to be careful, as not all applications that offer these security measures are enabled by default. In addition, there are other measures that applications can use to protect our privacy and security, especially when using them. For example, two-step authentication or the ability to delete sent images after a period of time.

Therefore, it is important that we know which messaging applications are the ones that offer the highest level of security to prevent our data and conversations from being exposed.

Encrypted messaging programs

As we have mentioned, messaging applications are not as safe as they may seem, since they can leave a door open for our conversations to be spied on. Next, we are going to see a series of messaging applications, which are characterized by encrypting end-to-end conversations for our greater security.

Ricochet, security through the TOR network

We are talking about an anonymous messaging service that, perhaps, is not popularly known. It is characterized by using the TOR network to be able to send messages and communicate with other people, without having to depend on a central messaging server. Therefore, all the messages you send are encrypted and secure.

In order to use this application, it is not necessary to register an account, as it automatically generates a unique identification for each user that we can share with our friends to chat safely. It has a fairly simple interface, to be able to add friends, chat and choose other configuration options.

Ricochet is available for Windows, Linux and macOS and we can download it from this link.

Wire, encrypted messaging for total security

This messaging service is characterized by the possibility of sending encrypted messages, calls, photos and files, without the need to have a phone number to use it.

Signal Private Messenger, one of the safest options

We are now facing one of the safest instant messaging applications that exist thanks to its strong protection encryption. It is a free and open source application that has a end-to-end encryption state-of-the-art to keep our chats safe.

We are talking about an application that is characterized by its security and having unique functionalities.

Telegram Windows 10

This application has a function called Secret chat. This is responsible for protecting messages with end-to-end encryption. Instead, it should be noted that this is not a default function so in order to use it it will be necessary to know how to activate it. In addition, it allows us to establish a four-digit code to prevent any intruder from accessing our messages in case of theft or loss.

Telegram is available for free for both mobile applications and computers with Windows, macOS and Linux operating systems. In addition, it has a web version that does not require having the application open on the mobile to be able to use it. We can download it from the developer’s website.

Wickr Me, encrypted messaging for individuals and companies

We are now talking about a messaging application that also stands out for its security since it is capable of offering end-to-end encryption both in messages and voice and video. It has a free personal version that allows you to send individual or group messages, make calls and receive files safely. It also has a secure deletion function that adds one more point of security, since it does not allow to recover files that have been deleted.

WhatsApp, the most popular app is also safe

Without a doubt, a benchmark when it comes to instant messaging, it is not in vain that it is used by more than 1500 million people around the world. Since 2016, the application incorporated the encryption protocol Open Whisper Systems created by Signal on all their mobile platforms. In this way, only the recipient and the sender have keys to decrypt the messages sent through the application, so that no one else will be able to see it. Likewise, both voice and video calls are also encrypted.

WhatsApp Desktop on Windows 10

Other security measures that it incorporates are the function of Confirm security code, with which we can confirm that both calls and messages are encrypted. As well as the two-step verification to add extra security to our account, by using a PIN code to check the phone number on any device we use.

WhatsApp is available for free and without advertising for mobile devices and computers with Windows or macOS. In addition, it has a web version. We can download it from their website.

Threema, with GDPR compliant end-to-end encryption

We are talking about an open source instant messaging application, designed to generate as little data as possible from each user. To ensure your security, all communication is end-to-end encrypted. The application hosts its own servers in Switzerland and is fully GDPR compliant. When we connect, a random ID is generated to configure, so linking our email address or our phone number is optional.

Threema

When using it, it is not possible to bypass end-to-end encryption using unencrypted message copies on the device. It does not have a fingerprint function and the received URLs are not opened automatically. Furthermore, messages are immediately and irrevocably deleted from the server once they have been delivered to the recipient.

Threema is compatible with mobile devices and also has a version that we can access from here.

Which secure messaging app to choose?

As we can see, we have at our disposal a good number of instant messaging applications that we can use safely, since they have end-to-end encryption. Beyond the most popular ones such as Telegram or WhatsApp, here we can find tools specially designed for the privacy and security of our data, of which we can highlight Ricochet Y Signal.

Both applications are characterized by having been designed to guarantee maximum security in our conversations. Ricochet is the only listing messaging service that uses the TOR network for our communications without relying on a central server. While Signal has a state-of-the-art end-to-end encryption, ensuring that no one can read our messages.
