Hi, The loop-AES.README file mention that the minimum password length in single-key mode is 20 characters. But, what is the maximum password length in single-key mode? Are there any other restrictions for the password? If it is possible to have *very* long passwords (random data), then it would be nice to have the possiblity to split up the single-key password to be used as the keys in the same way as the keys in the multi-key mode is used. For example: assume that you have a 2048 characters password. Split this password in 64 equal sizes and you will have 64 different passwords each with the length of 32 characters. Then, you should be able to use these passwords in multi-key mode (if the loop-AES is patched to be able to work with this setup, of course...).
