Subject: defining world mangling rules for passwords following certain restrictions

Dear all 

Ii am having troubles defining the JTR rules to handle passwords that follow certain restrictions. 

The passwords must follow this restrictions:

- must be between 8 characters and 16 characters
- includes at least 1 numeric character (0-9)
- includes at least 1 uppercase alphabetic character (A - Z) 
- includes at least 1 lowercase alphabetic character (a - z)
- includes at least 2 special characters, except ( ) % > " '
- should not includes 2 identical consecutive characters

Passwords are hashed by (md5crypt [MD5 32/64 X2])

Does any one have any idea on how to construct the rules for JTR to exclude all words that
do not correspond to this pattern ?

Thanks for any help / insights.
