Subject: passphrases with more than 160 bits of entropy

I was thinking that one could hash the first block, copy the
intermediate state, finalize it, then continue the intermediate result
with the next block, and finalize that.  Is this safe?  Is there a
better alternative?

Use a bigger hash, SHA-512 should be good to basically 512-bits, same for Whirlpool. If those aren't enough for you, use the chaining mode from Whirlpool and Rijndael with appropriate size. Joe
