Why Is Encryption Important for Messages?

Encryption is a technique used to convert information into secret code that covers the information’s true meaning. Encryption plays an important role in securing messages and enables confidentiality, authentication and integrity of digital communications. Encryption ensures that the sender and the receiver are the only parties that can read a message’s content. Outsiders cannot decrypt the message as internet service providers, hackers and other third parties do not possess the encryption key.

How Does Encryption Work for Messaging?

Encryption is a security method that keeps messages secure. End-to-end encryption converts messages into scrambled text, and the unreadable text can be decoded with a secret key. A secret key is a number that is created on the sender and receiver device, is deleted from the sender’s device when the encrypted message is delivered and is then deleted from the receiver’s device when the message is decrypted.

Note:

Internet service providers and message delivery servers might access messages but cannot read encrypted messages because the snooper does not have the secret key.

How Safe Are Encrypted Messaging Apps?

Most of the best encrypted messaging applications are so heavily encrypted that even governments, ISPs and law enforcement cannot break into the messages. Messaging apps use encryption, meaning only the sender and the receiver of a message can see the content. Some messaging apps need users to enable this feature, while others only encrypt messages in certain circumstances.

Can Hackers Read Encrypted Messages?

Yes, hackers can read encrypted messages on some occasions. This is because there is always the potential to discover a vulnerability in the app. For this reason, encrypted messaging apps that are open-source and run bug bounty programs are considered more protected.

There are many types of hackers that can steal the authentication code that holds the encryption data. This authentication token enables hackers to read any messages that come through.

What Are the Common Attacks to Messaging Apps?

The common attacks to messaging apps are given below.

  1. SMS phishing
  2. Premium-rate SMS scams
  3. Mobile malware
  4. Emotet
  5. Filecoder

Can Emails be Encrypted Like Messages?

an image with email encryption concept

Yes, emails can be encrypted like messages. Users can add an end-to-end encryption layer to emails, but users will need third-party apps. When installed, the user will need to provide the app’s permission and exchange public keys with the receiver. If users need to know how to encrypt an email, the simplest way is to use a secure email service with a built-in encryption framework. Otherwise, if users’ email supports encryption, different clients and add-ons can be used to send emails in encrypted forms using PGP or other encryption methods.
