and i also dont authenticate to AD.... my philosophy is this:
if you trust a Microsoft OS to secure your password, its not secure
at all. I watched someone the other day run this application that
blew right through a Windows administrator password.

Any algorithm is not "uncrackable" by nature, it's important to
have a high
enough computational security threshold to make brute forcing it
unrealistic. In the case of file vault I would probably focus on brute
forcing your password since I should be able to get into it quicker
then
brute forcing the AES key. That however could be days, months,
years of CPU
time depending on how strong it is.

How secure is it? 128bit does not sound that secure to me,
especially when email encryption goes up to 2048 bit.
If I have files of a top secret nature, is AES128 uncrackable? I do
not worry about my passphrase for logging in (and I am told that is
the password used to encrypt for filevault - it's very cryptic. I
also have just as cryptic of a passphrase for the master password),
but is there a way to crack what sounds like to be a very small
cipher (AES128?)
The reason I ask... would it be safer to use something like
Blowfish? I know AES is the standard for US encryption, but that
does not necessarily mean is the best available.
thanks,
