about

PassGen is a basic secure password generation package and associated cmdline tool. Generated passwords can be of arbitrary length, and conform to a few basic policies.

password policies

  • Alpha - mixed cased roman alphabet passwords

    ex: fdUhcJupKPzOIKBaLfqe
    
  • Numeric - numeric digits in range 0-9

    ex: 92167663796913288031
    
  • AlphaNumeric - combined Alpha and Numeric policies

    ex: Wll77E6bm6TA25agYu60
    
  • Printable - ascii characters in range 33-126 inclusive

    ex: AZn#))q<(m*f42F"+&9-
    
  • Special Characters - any of the basic policies, minus the all inclusive Printable policy -- can be augmented with specifying a string consisting of candidate "special characters". (Note that per your command line shell, you may need to suitably escape the special character string.)

    ex: ]06.8!2[699/][6[61\0 -- given Numeric policy with ".[]!\/" special characters spec.
    
  • No repeated seequences - any of the basic policies can be augmented with specifying a non-reptition of password character sequences. (Note that while some authorized domains specify this behavior, the use of non-repeated flag reduces the space of possible passwords.)

    ex: 14356954843130739693 -- given Numeric policy with no repetition constraint.
