What are the differences between AES and RSA encryption?

What are the differences between AES and RSA encryption?

AES (Advanced Encryption Standard) is a symmetric encryption method, while RSA (Rivest-Shamir-Adleman) is asymmetric. AES uses the same key for encryption and decryption, making it faster and suitable for large data. RSA uses a pair of keys (public and private), which makes it more secure for key exchange but slower for encrypting large data.

Which one is more secure?

Both AES and RSA are secure, but they serve different purposes. AES is considered very secure for encrypting data, while RSA is secure for transmitting keys. The security of both also depends on key length and implementation.

When should I use AES over RSA?

You should use AES when you need to encrypt large amounts of data quickly. Use RSA when you need to securely exchange keys or encrypt small amounts of data.

Can you give me an example of when to use each?

Sure! Use AES for encrypting files on your computer or data in transit. Use RSA for securely sharing the AES key over an insecure channel.
