Hmm, I guess you native-english speakers say something like "Don't count your chickens before they are hatched." :)
The yml above works fine ... but:
If I want to add a contraint like ...

constraints:
  - type: Length
    min: 8
    message: Your password should at least be 8 characters long

... the Callback filter messes up this constraint because it first hashes the password to a 40 characters long SHA1 string which therefor passes the contraint even if the entered string was less than 8 characters. I just tried to dig into Inflator/Validator/Transformer in hope to find something appropriate but I seems there are not many examples.
