I don't have a LM version of the password as I disabled LM hashes. I do have physical access to the system as it is my personal pc. What I did was create a user called test and set its password to TeSjtEsJTE. I ran pwdump7 to get the hashes. I am generating a table of time to crack a series of passowords. I need to see how it would take to crack my password using a custom character. I have the time it takes to crack using an alphanumeric charset. I created a new john.pot using your contents and then tried to generate a new char file using: john-386.exe --make-charset=cust.chr john.pot and I get Loaded 0 plaintexts, exiting... What did I do wrong? I have looked at using external, but I haven't found any examples of filters.
