Firstly, you need to know what encryption is. Encryption is a method of encoding data in such a way thus the information security is maintained and cannot be read without decryption. So, only the person concerned in communication can read the information, people or other parties will not be able to read it, whether the internet service providers, software companies and the government.


Of course, this method is expected to guarantee user data from cybercriminals. Reported by Heimdal Security, the encryption key will be stored in the user’s local storage for more security. Therefore, knowing information about an application’s encryption policy is very important when considering to install applications on devices, both personal devices, and shared devices.

Then what are the best-recommended applications in data encryption?

Heimdal Security has made a list of applications, especially the most recommended social networking applications in terms of data encryption so that it is safer to use to communicate privately. Recently, Facebook, today’s largest social network, has reportedly shared user data in Cambridge Analytic Case. Terrible, right?
Therefore, it is important to pay attention to the flow of our privacy in the digital world, in particular.

Indonesia is one of the countries with the most social network platform user. Here is the list of social network platform often used by Indonesian that has a good security policy regarding encryption.

1. Whatsapp

WhatsApp, a social network that Facebook has acquired, is unexpectedly crowned by Heimdal Security as the best application in terms of encryption. Indeed, since 2016, WhatsApp has implemented an end-to-end encryption system so that user conversation data is safer because WhatsApp does not store user data on its server but on the user’s local storage.


That is why WhatsApp will periodically back-up your data, sometimes even with large amounts of data size. But that’s how hackers will have more difficulty describing your conversation data in this application.


Internet users in Indonesia are also familiar with the Japanese-made LINE social network. The application, which was originally created as a telecommunications solution after the 2011 Tohoku earthquake, from the beginning had an end-to-end encryption feature called Letter Sealing.


3. Telegram

Telegram is also one of the most widely used social networks in Indonesia. With a slogan that prioritizes speed and security, Telegram has the Secret Chats feature in the application’s advanced settings to ensure more privacy to its users. So when a user deletes a conversation on one side, then the chat on the other party in question will also be automatically deleted.

In addition, there is also an option to delete conversation data within a period of time that can be determined by the user. Of course, this application applies end-to-end encryption so that user data will not be stored in the Telegram cloud but on the user’s local device.


4. Kakaotalk

It turns out that the Korean messaging application, KakaoTalk also applies the Secret Chat feature like the Telegram. However, KakaoTalk does not set the end-to-end encryption method by default so users must activate it first. Reported by Heimdal Security, KakaoTalk is indeed used by more than 90% of smartphone users in South Korea who uphold their privacy.


5. Signal

This application may rarely be used in Indonesia, but just in case you have to look for another alternative way to communicate with your community, you’ll need this messaging app made by Whisper System that allows you to do calls and messaging with encryption method. 

Signal already acquired by Twitter in 2011 to improve their security issue. This app also has an open-source encryption engine that allows everyone to inspect the code. Of course, it has already end-to-end encrypted by default. This app is free and able to operate in a various mobile platform, fast without any advertisement.


Beside those apps, you may consider Luxembourg-made messaging app, Viber.
Also Dust that use AES 128 and RSA 248 encryption, Threema that has PIN-enter only Private Chat feature,
2015 Best Business – Best Mobile App winner app PryvateNow and Wire that works on various platforms such as Windows, Android, iOS, macOS, Linux, and different browsers (Chrome, Firefox, Edge, Opera).
