The role of encryption in secure communications

In an interconnected world, where electronic communications are the backbone of our daily interactions, encryption has become a critical element to ensure the security and privacy of the information we share online.

What would happen if encryption did not exist?

Let’s imagine a world in which encryption did not exist. In this scenario, any data we shared online, from our passwords and credit card numbers to our personal conversations, would be completely exposed to prying eyes. Cybercriminals, governments and other unscrupulous entities could have unlimited access to our most intimate secrets and most sensitive information. This would lead to an epidemic of identity theft, financial fraud and the erosion of trust in digital communications.

Not only individuals would suffer the consequences. Companies would have their trade secrets and customer data stolen, which could bankrupt many of them. Governments would be unable to ensure national security or protect classified information. Society as a whole would be plunged into digital chaos, where trust and privacy would fade, undermining people’s ability to interact, trade and collaborate securely online.

Encryption, therefore, plays an essential role in preserving security and privacy in the digital world. By ensuring our data is secure and our communications are confidential, we enable modern society to function efficiently and securely. But beware! Not every service that claims to be encrypted guarantees your security,

What is Encryption?

Encryption is a process by which information is converted into an unreadable format and can subsequently be decrypted only with a decryption key. This technique is used to protect the confidentiality and integrity of data in transit or in storage. Encryption is based on complex mathematical algorithms that transform data into an encrypted code, making it extremely difficult or virtually impossible for unauthorized third parties to access or understand the information.

The application of encryption nowadays.

Nowadays, encryption is a common feature in many apps and devices we use every day. Are your communications really secure?

Secure Messaging Apps: Messaging platforms such as Silent Circle, Armadillo, Threema, Vault, Salt or VNCLaggon use end to end encryption to ensure that only the sender and receiver of a message can access its content. Even the service provider cannot decrypt the message, which means your conversations are private and secure. Learn about the essential tools and software to achieve secure communications.

Although some other applications such as Telegram, Whatsapp or Signal claim to have end to end encryption, it is not as secure as others, not to mention that they are applications with privacy policies that do not benefit the user.
