    show length of Password in generator window.

    Hello, sorrowly, the length of the Password isn't shown so far.
    I set it first in the Spinedit (edit/Text with arrows), of course.

    But alone the strength in bits is presented with the result, but not the simple length.

    I could imagine that some people use the keygen to test their own passwords
    No one uses only "created by a machine" passwords.
    Many carry their old passwords over years and only want to view the strength now, instead of generating a new one. (of course it's not besst way, but - might happen)

    So please implement/increase the little label with length. (5 min job?)

    Ehm, and concerning this ...

    has the following 31 letter long password really only 140 bits .... or 143 bits indeed?
    "blabla hier bitte Länge angeben"

    Many thanks ... good program.

    Why is password length important?

    has the following 31 letter long password really only 140 bits .... or 143 bits indeed?

    The password estimation algorithm used by KeePass is described briefly here. As described, password strength, typically reported in bits, is an estimate not an exact value. Some variability in the strength estimate of similar but different passwords is to be expected.

    Your example of a five word password is an example of a password that does not match the KeePass estimation algorithm assumptions very well. Unless the words are found in KeePass' 1500 word library, the KeePass password strength estimator will grossly overestimate the password strength. A better estimate, but still probably over optimistic, is to treat that password as a diceword phrase. The entropy attributed to each word in a diceword phrase is 13 bits. Since there are 5 words, the entropy of this phrase is closer to 65 bits.

    For more information about password strength see http://en.wikipedia.org/wiki/Password_strength
    For information about diceword passwords see http://en.wikipedia.org/wiki/Dicewords
