comment How long does it take a quantum computer to brute force AES?
the biggest number factored so far by a quantum algorithm is something like 64. That's six four. Don't hold your breath.

comment Guarding against cryptanalytic breakthroughs: combining multiple hash functions
suppose I have a very short message, and H(x)=x. Again, a very bad hash function. But catenating that hash with any other hash function reveals the message.

comment Guarding against cryptanalytic breakthroughs: combining multiple hash functions
Suppose I design a very bad hash, such that all it's output bits are ones. How would concatenating that hash with another hash be as strong as the other.

My argument is that if you can design hash functions with certain characteristics, if you just pick two hash functions and combine them, you might. So yes, you might improve things, or not.

comment Master keys for decrypting?
Interesting. Does that mean that the key escrow system could be applied to any underlying encryption algorithm?

comment Why is AES resistant to known-plaintext attacks?
the classic random number generators you find in Knuth have only a couple integers as their internal state.
