Differences Between Rijndael and AES

Question

I\'m investigating encryption algorithms - can someone give me a quick rundown of the differences between Rijndael and AES?

Answer 1

AES is a reduced version of Rijndael where it is only defined for block sizes of 128 bit whereas Rijndael is defined for block sizes of 128, 192 and 256 bit. If a different block size between encryption and decryption is used, then it is not possible to recover the original plaintext.

Rijndael-256 and Rijndael-192 must be seen as completely different algorithms from AES (Rijndael-128). They are inherently incompatible.
