What are the differences between AES and DES encryption?

What are the differences between AES and DES encryption?

AES (Advanced Encryption Standard) is more secure and efficient than DES (Data Encryption Standard). DES uses a 56-bit key, while AES supports key sizes of 128, 192, or 256 bits.

Why is AES considered more secure than DES?

AES is considered more secure because it has a larger key size and a more complex encryption algorithm, making it resistant to brute-force attacks.

Can you explain how the encryption process works in both AES and DES?

Sure! In DES, data is divided into 64-bit blocks and processed through 16 rounds of permutation and substitution. In contrast, AES operates on 128-bit blocks and uses a series of transformations over multiple rounds, depending on the key size.

Are there any real-world applications where AES is preferred over DES?

Yes, AES is widely used in various applications, including secure communications, file encryption, and data protection in cloud services, due to its enhanced security.
