If AES is a safe, hashing algorithms are more like smart paper shredders. Hashing takes the original data—like your password—and turns it into a fixed-length random code called a hash. Interestingly, this process is one-way , meaning you can’t revert the hash back to its original form. Examples of popular hashing algorithms include MD5, SHA-256, and bcrypt.
Hashing is commonly used to store passwords in a database. When you log in, the system compares the hash of the password you entered with the stored hash. If they match, access is granted. However, hashing buy phone number list also has certain drawbacks that you need to be aware of. Hang on, we’ll get to that!

How Does AES Encryption Work?
AES works with three key sizes: 128-bit, 192-bit, and 256-bit. The larger the key, the harder it is to crack. The process involves steps like byte substitution, row swapping, and column shuffling—it sounds complicated, but the gist is that the data is scrambled in a way that makes it extremely secure.
For example, if you have a password “secret123”, AES will change it to something like “7b9k2p...” which is completely unpredictable. Cool, right? But since AES is symmetric, the encryption key must be stored securely. If the key is leaked, all the security of AES is wasted. This is one of the points to keep in mind if you want to use AES for passwords.
