Hashing works differently. Imagine you input “secret123” into a hashing machine like SHA-256. It outputs a long string like “a1b2c3d4...” that is unique to that input. If you changed just one letter in “secret124,” the hash would be something completely different, like “x9y8z7...”.
This uniqueness makes hashing very suitable for password verification. But there is an important note: hashing is not designed to store data that needs to be opened again. So, if you need the original data back, hashing is not the answer. This is very different from AES which can be returned to its original form.
Advantages of AES Encryption
AES has several advantages that make many people choose it. First, its buy phone number list speed . AES is designed to work fast, even on low-spec devices. Second, its strength . With a 256-bit key, AES is nearly impossible to crack with current technology—except perhaps by future supercomputers.
Third, AES is flexible. You can use it to secure files, communications, or even entire hard drives. So if you need a versatile solution for data security, AES is a solid choice. But this power comes with a catch: the key must be guarded fiercely.
Disadvantages of AES Encryption
Nothing is perfect, including AES. One of its biggest weaknesses is its reliance on keys .
