In today's world, everyone uses messaging apps. Many users prefer using messengers with built-in strong encryption for obvious reasons, from confidentiality to hiding data from researchers. Such an app is used by messengers because of the confidentiality and privacy they offer. Many social media application messengers and are considered to be the most used messengers in today’s world, along with many other messenger applications, used by people living in regions known for corruption. Many social media messenger applications are free, open-source apps for iOS and Android mobile devices, PC, and Mac. It was Edward Snowden who called Signal the world's most trusted messenger on his Twitter account in 2015. app offers end-to-end encryption, allowing users to send encrypted group and single text messages, photos and video files, and make encrypted phone and video calls without being overheard during transmission. The messenger uses the ZRTP cryptographic protocol and an AES algorithm (Advanced Encryption Standard) with a key length of 128 bits. Second, a secure encryption protocol. The main difference between such applications and its current competitors lies in the reliable encryption algorithms. The security community highly appreciates the cryptographic scheme used by Messenger. Third, store encryption keys in Android KeyStore. Like the iOS keychain, the Android KeyStore is a storage location that contains software and hardware encryption keys on running devices. Java programs use the KeyStore to encrypt data, authenticate and establish an HTTPS connection.
