Secure messaging apps

05 Jul 2015


In the aftermath of the Snowden revelations in June 2013, digital security and privacy have become new buzzwords and garnered immense significance. Snooping of your private information online is a reality, whether you are using Facebook Messenger or WhatsApp. Once signed up to any social media website like Facebook or Twitter, users willingly agree to disclose their data which can be shared with third parties or even the government if required to be disclosed. But there are apps that can secure your messaging when installed; four such secure messaging applications are shared below:

1) Wickr

Wickr claims to be a self-destructing messaging app and offers military grade encryption. It allows to send messages securely and anonymously. Your contact book will not be uploaded to their servers and remain private. It removes all records, geotags and identifying information from your messages and media. Wickr offers a configurable timer for expiration purposes in regards to the messages sent. No user data is collated and collected by the company. Wickr uses AES 256-bit encryption key for each individual messages sent. It can be downloaded for iOS from this URL: and for Android:
