We currently have the tags rijndael (59 questions tagged) and aes (1135 questions tagged).
Since all Rijndael questions tend to boil down to being about AES, it could make sense to make rijndael a synonym of aes.
Should we merge the Rijndael tag with the AES tag, making it a synonym of the later? Is there any reason not to do so?
