"Some ciphers" is probably not enough for those who frequently ask
about that topic. I

I think it's a good idea to stress you're talking about the block size,
not about the key size. Something like "a cipher with a 64 bit block size".

What do you thing of
But what happens if two identical ciphertext blocks are found in the

I had someone wonder why the FAQ recommends avoiding CAST, BLOWFISH,
IDEA, or 3DES for bulk encryption. It occurs to me that this is a
pretty reasonable question and probably should get placed in the FAQ.
So, here's proposed new content -- please feel free to chime in with
