What is the difference between Rijndael and AES?
The difference between Rijndael and AES lies primarily in their key and block sizes.
In summary, Rijndael is a more generalized block cipher algorithm that allows for a wide range of key and block sizes, while AES is a specific variant of Rijndael with fixed key and block sizes and a standardized number of rounds. AES is widely adopted and recognized as the industry standard for symmetric encryption.
