Thanks for clarifying, you are (of course) right. Didn't think for a
second before posting :-(

However, I wanted to demonstrate the relationship between the
length/keyspace of a password and the cryptography actually used. 
Or the other way 'round: why use (waste?) a lot of bits on
cryptography when it's much "easier" to bruteforce the 
password itself?
