What is the difference between Rijndael and AES?

What is the difference between Rijndael and AES?

AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits and a maximum of 256 bits. … AES is the successor of the Data Encryption Standard (DES).

What is difference between DES AES?

DES (Data Encryption Standard) and AES (Advanced Encryption Standard) both are the symmetric block cipher. … The basic difference between DES and AES is that in DES plaintext block is divided into two halves before the main algorithm starts whereas, in AES the entire block is processed to obtain the ciphertext.

What is rc4 for?

What is RC4? RC4 was designed in 1987 by Ron Rivest and is one of the most widely software stream cipher and used in popular protocols, such as SSL (protect Internet traffic), WEP (secure wireless networks) and PDF. It's considered to be fast and simple in terms of software.

Is AES better than DES?

AES data encryption is a more mathematically efficient and elegant cryptographic algorithm, but its main strength rests in the option for various key lengths. AES allows you to choose a 128-bit, 192-bit or 256-bit key, making it exponentially stronger than the 56-bit key of DES.
