What is end-to-end encryption?

In recent years, many messaging apps have been announced using end-to-end encryption for secure communication services. In this article, we will discuss what end-to-end encryption is, and how we are using them. 

WHAT IS END-TO-END ENCRYPTION?

There are always some vulnerabilities involved whenever you send data such as photos, voice notes, credit card credentials and documents over the internet. There is always a server between the sender and receiver over the internet, which can affect privacy. End-to-end encryption is the act of sending messages to the recipient in a secure way so that no one can decrypt the messages other than the sender and receiver. In simple words, end-to-end encryption is an asymmetric security protocol that keeps your data secure. It is a standardized mechanism of protecting two-way communication.

HOW END-TO-END ENCRYPTION WORKS?

In end-to-end encryption, text messages, video files, documents, and other data are encrypted before being sent from the sender’s device and decrypted only when it reaches the recipient’s phone or computer. In this way, intruders and hackers cannot access the information on the server as they do not have the private key to decrypt at the recipient’s end. 

By creating a public-private key pair, end-to-end encryption provides security. This method of securing and decrypting messages relies on unique cryptographic keys, also known as asymmetric cryptography. In cryptography, public keys are generally distributed and are used to encrypt and lock messages. Messages can be encrypted or unlocked with private keys that are only known to their owner. The data is encrypted from end to end, so it cannot be decrypted even by the server. In other words, even if they wanted to, the communication service provider could not intercept or manipulate the data. Law enforcement and government agencies cannot access the data. Only the parties at both ends can, no one else.

Some encryption services encrypt data when transferred between them but only protect it from intruders and hackers. Take the example of two messaging app users chatting through instant messaging. When their data is transmitted from one user to another, it is routed through the application’s server.

IMPORTANCE OF END-TO-END ENCRYPTION

The primary importance of end-to-end encryption is that it provides a secure connection between the sender and receiver transmitting their sensitive information.. Moreover, it ensures that messages with sensitive information are protected from third-party service providers. If the communication services providers gain access to the decryption keys, they would be able to access the content of users’ data stored on their servers. In the past, Google had been able to deliver targeted ads to Google account holders due to their possession of decryption keys. Fortunately, in good end-to-end encryption, messaging services providers can never gain access to the decryption keys.

Another benefit of end-to-end encryption lies in the knowledge that your communications are secure against prying eyes. You might want to protect business communications and financial transactions using end-to-end encryption along with simple two-way text chats. 

ADVANTAGES OF END-TO-END ENCRYPTION

Below are the advantages of end-to-end encryption:

  • Promotes data protection
  • Prevents unauthorized access
  • Use digital signatures
  • Data can be decrypted only by the owner of the decryption key
  • Keeps your data safe from intruders and hackers
  • You cannot be manipulated through your data
HOW FORTKNOXTER USES END-TO-END ENCRYPTION

Fortknoxter uses end-to-end encryption to boost several privacy features in their app, giving users enough confidence to use the app without any privacy concern. 

  • Blockchain Integration
  • Zero-Knowledge Architecture
  • Confidentiality
  • Integrity
  • Design Privacy
  • Digital Signature

FortKnoxster automatically encrypts every call, message, and file sent or received. Users do not need to boost this feature on their devices manually. During the creation of a FortKnoxster account, several cryptographic vital pairs are generated on your device for encrypting and decrypting messages and other files such as documents, pictures or credentials. With your password as your encryption key, these private keys are protected, but only you and no one else knows it. In FortKnoxster, you can exchange public keys securely with your contacts and other users. That way, others can encrypt messages to you, and you can decrypt messages from them. We use public-key cryptography with strong 256-bit AES encryption that allows the access of data to only authorized users. 

Another vital privacy feature we have integrated into our messaging app is zero-knowledge architecture. With FortKnoxster, the user’s password never leaves the device and is never shared with anyone! With FortKnoxster, you are always in control of your data. Also, FortKnoxster never transmits or stores passwords in plain text, due to no-knowledge authentication of passwords. Hash-based encryption protects this. 

We have taken the security of your communications to the next level by securing them with encryption using the Binance Smart Chain. This is done by storing a cryptographic hash of every user’s public identity and encryption keys in a decentralized smart contract. The best thing that will surprise you is that there are absolutely no annoying ads or spam notifications.
