What are the different types of encryption algorithms?

There are several types of encryption algorithms, including symmetric, asymmetric, and hashing algorithms. Symmetric algorithms use the same key for encryption and decryption, while asymmetric algorithms use a pair of keys. Hashing algorithms, on the other hand, transform data into a fixed-size string of characters.

Can you give examples of each type?

Sure! For symmetric algorithms, examples include AES and DES. For asymmetric algorithms, RSA and ECC are commonly used. SHA-256 is a popular hashing algorithm.

How does AES work?

AES, or Advanced Encryption Standard, is a symmetric encryption algorithm that encrypts data in fixed block sizes of 128 bits using key sizes of 128, 192, or 256 bits. It operates through a series of transformations including substitution, permutation, and mixing of the input data.

Is AES secure?

Yes, AES is considered very secure and is widely used in various applications, including securing sensitive data and communications.
