I am using openssl APIs for AES in my code. What I noticed that AES APIs do not go above 256 bits. I am just curious if this is a limitation within openssl code or if 512 bits with AES is just an overkill.

Wikipedia says (in the footnote):
The Rijndael algorithm seems to work only for a maximum size of
256bits.
