We've all already turned off RC2, RC4, DES, IDEA, and more. We are down to just 3DES and its replacement, AES. With the new BWAIN threatening 3DES (and blowfish), we seem to just have AES (and maybe the not-always-supported Camellia.
So, when we get a new BWAIN that AES is broken, what then? Seriously. We are turning off these things faster than they are being made.
