passcheck go library

This go library allows you to define password policies and check if a given password matches the requirements.

Example

yourPassword := "helloWorld123!"
err := passcheck.Check(yourPassword, []passcheck.PasswordCheck{
    passcheck.MinLengthCheck(8),
    passcheck.MaxLengthCheck(64),
    passcheck.MinLowerLetterCount(4),
    passcheck.MinUpperLetterCount(2),
    passcheck.MinDigitCount(2),
    passcheck.MinSpecialCharCount(3),
})

Special characters

For checking the special characters, the library has the variable passcheck.SpecialChars. You can change the variable to specify the set of characters, which should count as special characters.

passcheck.SpecialChars = "+-!"

Customizing errors

The errors, which are returned, when a case fails, are variables, which can be modified. Set the error variables with the error you want, e.g. to customize the error messages.

passcheck.ErrMinLength = errors.New("das passwort ist zu kurz")
