Data encryption: what is it and how does this protection work?

The security of our communications and information should be our primary concern. As you know, online data and privacy are becoming increasingly vulnerable. This also applies to ambassadors!

Apps like WhatsApp and Telegram promise to protect our conversations with encryption, but what exactly does this mean? And more importantly, to what extent does this actually provide greater security? This is what we will see now!

What is data encryption and what is it for?

A. data encryption It is a security technique that involves converting information into an unreadable format called a “cryptogram” during transmission or storage.

This transformation is accomplished through complex mathematical algorithms and encryption keys that ensure the information is only accessible to authorized individuals who have the correct key.

Mother purpose of encryption is to guarantee the confidentiality and integrity of information. Let’s better understand how it plays this essential role:

1. Security: Encryption protects your personal data and confidential information such as: passwords, credit card numbers This private messages. When you send or store encrypted data, Even if malicious third parties obtain this information, it remains unreadable and useless. without the appropriate decryption key.
2. Integrity: Encryption not only keeps your data private but also ensures that your data remains private. not tampered with during transmission. Any attempt to modify encrypted data will result in immediate detection of corruption.
3. Originality: Encryption is also used to authenticate. originality data sources. For example, secure websites use SSL/TLS certificates to ensure that you are truly connecting to the intended website and not a fake website.
4. Protection against digital threats: Encryption helps protect against digital threats such as: malware This hacker attacks. Even if an attacker gains access to your data, it will remain inaccessible without the decryption key.

How does encryption work? WhatsApp and other messaging apps?

To understand this better, imagine you want to send a secret text message to a friend and you don’t want anyone but your friend to read it. This is the common path followed by the application:

• Plain text: your original message.
• Encryption key: a secret key that tells how to scramble the message.
• Cryptography: Applying the key to convert the original message into an unreadable version.
• Encrypted message: The resulting message is sent securely after encryption.
• Front desk: Your recipient receives the encrypted message.
• Decryption Key: the same key is used to reverse the encryption process.
• Decoding: The encrypted message is converted into the original text so that only people with the key can read it.

Here, encryption key It plays a fundamental role in communication security. Without this private key it is almost impossible for anyone to decrypt the encrypted message. NEven the app can read The content of the message makes the communication between you and your friend safe and confidential.

This is just a simple example of encryption. In real scenarios, much more complex mathematical algorithms are used to protect sensitive information.

Is it possible to have this level of security beyond messaging apps?
