This question already has an answer here:

Why did the Rijndael cipher become the Advanced Encryption Standard instead of Twofish and Serpent? Do Serpent and Twofish have security issues or weak keys? Or is it just slower? I know that some modern cryptography programs use twofish and serpent?

Sorry for the dumb question .
