How Does Encryption Work?

Encryption is key to keeping data safe and secure. It changes plain text into a code that only those with the right key can read. Let’s dive into the steps of this process.

Encryption and Decryption

First, we start with plain text, which is easy to read. This text is then encrypted using a special algorithm and a key. The encrypted text looks like gibberish to anyone who shouldn’t see it.

To get the original text back, you need the right decryption key. The strength of encryption comes from the algorithm’s complexity and the key’s length. Secure methods like Advanced Encryption Standard (AES) and RSA use long keys to prevent hackers from guessing them.

Symmetric and Asymmetric Encryption

• Symmetric Encryption: Uses the same key for both encrypting and decrypting. It’s quick but requires the key to be shared safely.
• Asymmetric Encryption: Needs two keys – a public one for encrypting and a private one for decrypting. This is safer because the private key stays secret.

Knowing about encryption and how to manage keys is vital for keeping data safe. By understanding encryption, we can protect our sensitive info from those who shouldn’t have it.

Types of Encryption

In the world of data protection, there are two main types of encryption: symmetric-key encryption and asymmetric (public-key) encryption. These methods are key to keeping your information safe from cyber threats, like phishing attacks.

Symmetric-Key Encryption

Symmetric-key encryption uses one key for both encrypting and decrypting data. It’s fast and efficient, great for big data sets. But, sharing the key safely is hard, as the wrong hands can unlock your data.

Asymmetric Encryption (Public-Key Cryptography)

Asymmetric encryption uses two keys: one public for encrypting, and one private for decrypting. You can share the public key safely, keeping the private key secret. This method is slower but more secure, with features like digital signatures.

Choosing between symmetric-key encryption and asymmetric encryption is crucial for protecting your data. Both methods are vital in fighting cyber threats, including phishing attacks. Knowing the differences helps you pick the best way to secure your digital info.

Common Encryption Algorithms
