When talking about ways to keep data safe, there are a few common methods you'll come across, especially if you're looking into network security. Here’s a simple explanation based on what I’ve learned:
Symmetric Encryption: This means using the same key to lock (encrypt) and unlock (decrypt) data. It's quick and works well for large amounts of data. Some popular types are AES (Advanced Encryption Standard) and DES (Data Encryption Standard). You’ll often see it used to protect files and databases.
Asymmetric Encryption: This method uses two keys. You have a public key for locking the data and a private key for unlocking it. RSA (Rivest-Shamir-Adleman) is a well-known example. It's really useful for keeping data safe when sending it over the internet, like during online shopping or messaging.
Hash Functions: Even though they aren’t exactly encryption, hash functions like SHA-256 take a piece of input and turn it into a fixed-size string of characters. They are mainly used to check if data has changed during sending.
Understanding these methods is really important when you are working on network security. They help you choose the right tools and understand how to make a secure network.
