USAGE
    apg [-sdyltqhv] [-a algorithm] [-M mode] [-E string] [-n count] [-m length]
    [-x length] [-r file] [-b file] [-p length] [-c seed] 

DESCRIPTION
    apg generates several random passwords. It uses several password generation
    algorithms (currently two) and a built-in pseudo random number generator.

    Default algorithm is pronounceable password generation  algorithm  designed
    by Morrie Gasser and described in A Random Word Generator For Pronounceable
    Passwords National Technical Information Service (NTIS)  AD-A-017676.   The
    original  paper is very old and had never been put online, so I have to use
    NIST implementation described in FIPS-181.

    Another algorithm is simple random character generation algorithm,  but  it
    uses  four  user-defined  symbol  sets to produce random password. It means
    that user can choose type of symbols that should appear in password. Symbol
    sets  are:  numeric  symbol  set  (0,...,9)  ,  capital  letters symbol set
    (A,...,Z) , small letters symbol set (a,...,z) and special  symbols  symbol
    set (#, at ,!,...).

    Built-in  pseudo  random number generator is an implementation of algorithm
    described in Appendix C of ANSI X9.17 or RFC1750  with  exception  that  it
    uses  CAST  or SHA-1 instead of Triple DES.  It uses local time with preci-
    sion of microseconds and random device (if available)  to  produce  initial
    random seed.

    apg also have the ability to check generated password quality using dictio- 
   nary. You can use this ability if you specify command-line options -r dict-  
  file  or  -b filtername where dictfile is the dictionary file name and fil-   
 tername is the name of Bloom filter file. In that dictionary you may  place    
words  (one  per  line)  that should not appear as generated passwords. For    
example: user names, common words, etc. You even can use one of the dictio-    
naries  that  come  with  dictionary  password crackers.  Bloom filter file    
should be created with apgbfm utility  included  in  apg  distribution.  In    
future  releases  I  plan to implement some other techniques to check pass-    
words  (like  pattern  check)  just to make life easier  The options are as    
follows:
    
    -a    use algorithm number for password generation where number is:
                0 - pronounceable password generation
                1 - random character password generation

    -n count
          generate count number of passwords. Default is 6.

    -m length
          generate password with  minimum  length. If  minimum length > maximum
          length then maximum length = minimum length. Default minimum password
          is 8.

    -x length
          generate password with  maximum  length. If  minimum length > maximum
          length then maximum length = minimum length. Default  maximum  length
          password length is 10.

    -M mode
          Use symbolsets specified with mode for password generation. mode is
          a text string consisting of characters S, s, N, n, C, c, L, l.
          Where:

          S     generator must use special symbol set for every generated
                password.

          s     generator should use special symbol set for password genera-
                tion.

          N     generator must use numeral symbol set for every generated
                password.

          n     generator should use numeral symbol set for password genera-
                tion.

          C     generator must use capital symbol set for every generated
                password.

          c     generator should use capital symbol set for password genera
                tion.

          L     generator must use small letters symbol set for every generated
                password (always present if pronounceable password generation
                algorithm is used).

          l     generator should use small letters symbol set for password
                generation.

          mode cannot be more than 4 characters in length.

          Note:
          Usage of L, M, N, C will slow down password generation process.

          Examples:
          -M sncl or -M SNCL or -M Cn

    -E string
          exclude characters in string from password generation process (in
          pronounceable password generation mode you can not exclude small
          letters). To include special symbols that can be recognized by shell
          (apostrophe, quotes, dollar sign, etc.) in string use the backslashed
          versions.

          Examples:
          Command apg -a 1 -M n -n 3 -m 8 -E 23456789 will generate a set of
          passwords that will look like this
          10100110
          01111000
          11011101

          Command apg -a 1 -M nc -n 3 -m 26 -E GHIJKLMNOPQRSTUVWXYZ will gen-
          erate a set of passwords that will look like this
          16A1653CD4DE5E7BD9584A3476
          C8F78E06944AFD57FB9CB882BC
          8C8DF37CD792D36D056BBD5002

    -r file
          check generated passwords for their appearance in dictionary file.

    -b file
          check generated passwords for their appearance in filter file. filter
          file should be created with apgbfm utility.

    -p length
          this option tells apg to check every substring of the generated pass-
          word for appearance in filter file. If any of such substrings would
          be found in the filter file then generated password would be rejected
          and apg will generate another one. length specifies minimum substring
          length to check. This option is active only if -b option is defined.

    -c seed
          use seed as a random seed for password generation.

    -s    ask user for random sequence for password generation.

    -d    do NOT use any delimiters between generated passwords.

    -y    print generated passwords and crypted passwords.

    -q    quiet mode (do not print warnings).

    -l    spell  generated  passwords. Useful when you want to read generated
          password by telephone.
          WARNING: Think twice before read your password by phone.

    -t    print pronunciation for generated pronounceable password.

    -h    print help information and exit.

    -v    print version information and exit.

DEFAULT OPTIONS
    apg -a 0 -M sncl -n 6 -x 10 -m 8

    If you want to generate really secure passwords, you should use option -s.

EXIT CODE
    On successful completion of its task, apg will complete with exit code 0.
    An exit code of -1 indicates an error occurred. Textual errors are written
    to the standard error stream.
