comment How to encrypt data and know it will be secure for at least a few decades?
When combining multiple ciphers, ( provided their keys do not have a strong linear relationship ) security increase greatly. Also, I thought about what I said with the two 64-bit block ciphers, and this might actually be a good idea to introduce more key material to the block, since Blowfish has a maximum of 448-bits ( I think? ) wide key.

Also, the estimate of the time it would take to break Serpent came from an official document, it said that Rijndael would probably be secure for at least twenty years. Serpent, which is widely considered more secure than Rijndael as far as I can tell, would therefore ( according to common sense ) last longer, by how much, I am not sure.

Yes, I'd support the hashing idea. However, Serpent really is secure. Even the XLS attack won't weaken it much. After all, the AES submissions were expected to last for a long time, if I can remember right ( don't hold this against me, my memory is less effective than a goldfish's ) it was more than "a few decades".

accepted Other than brute force, are there any attacks on Threefish-512 using only a single known plaintext block?
