The following is the encrypted file: enc.pdf with the password 07.

Using the command pdfrip -f enc.pdf custom-query {0-98} --add-preceding-zeros manages to find the password just fine.
But fails when I give the command pdfrip -f enc.pdf custom-query {0-99} --add-preceding-zeros

I don't know if this is maintained but the issue is that, min_digits is set to the length of size when instead it should be based on the last number in the given range. Since, there can be many ranges separated by commas, min_digits will need to vary for every range.
