what i understand now that every algorithm need a hash to work with, is that right

comment Does encrypting twice using the same block cipher produce a security weakness?
@poncho u may be logic when i read it i miss understand, they mean if i use the cipher text to encrypt again with another algorithm like what happen in truecrypt.. AES-twofish-serpent.. but never know why that could make it less secure?

comment Is AES restricted to only 64 characters for the key/password?
so i can use 1000 characters password in AES PBKDF2, cuz PBKDF2 convert the password to something else that used to encrypt the data, right

The maximum volume password length has been decreased from 100 to 64 characters. This was necessary to avoid the following: When a password longer than 64 characters was passed to HMAC-SHA-1, the whole password was first hashed using SHA-1 and the resultant 160-bit value was then used instead of the original password (which complies with HMAC-SHA-1 specification), thus the password length was in fact reduced.
