Hi,

If a password is for example 128bit, how long is it in characters (a-z
& A-Z)?
How can i calculate this?

If the password is "THISisMYpassword". How many bit password is it?


I think you're misinterpreting something. 128-bit security has nothing to
do with the length of the password. It's the level of coding the security
uses, to try to express it simply. But to take your question literally,
the password if we store the password as 8-bit bytes it would be 14
characters, but usually it is encrypted before storing.

Didn't Windows change to use of Unicode from Ascii for passwords
some time back, IIRC when the length was greatly increased in the
NT4 to W2k transition? If so, then these are 16 bit chars.

However, prior comments are right on. There is probably some
confusion here between cipher key lengths, password hashes as
stored, and passwords.
