How do AES and DES differ in terms of security and performance?
AES (Advanced Encryption Standard) is generally considered more secure than DES (Data Encryption Standard) due to its longer key lengths and more complex structure. DES uses a fixed key size of 56 bits, while AES supports key sizes of 128, 192, or 256 bits.
What makes AES more secure than DES?
AES's security comes from its larger key sizes and a more complex encryption process, which makes it resistant to brute-force attacks. DES, with its shorter key length, is vulnerable to such attacks.
Are there any performance differences between the two?
Yes, AES is generally faster than DES on modern hardware due to its efficient algorithm design. However, the performance can vary based on the implementation and the specific use case.
Which one should I use for my application?
For most applications, AES is recommended due to its stronger security and better performance. DES is considered outdated and should be avoided.
