I am trying to achieve: ./john --mask'[*!][Ff]irrstword followed by a known number such as 11334 but could also be 43311 followed by [*!][Ss]econdword followed by 11334 or 43311' passwd The number digits would not change and would always be in the same order following the first and second word so could be treated as a "word". The firstwordnumber and secondwordnumber could also be reversed ie. ./john --mask'[*!][Ss]econdword followed by 11334 or 43311 [*!][Ff]irrstword followed by 11334 or 43311' passwd I assume this would need two passes, one for each combination? Can you assist please?
