WAPG(1) User Manual WAPG(1)
NAME
WAPG - generates several random passwords
SYNOPSIS
WAPG [-a algorithm] [-M mode] [-E char_string] [-n num_of_pass] [-m
min_pass_len] [-x max_pass_len] [-r dictfile] [-b filter_file] [-p
min_substr_len] [-c cl_seed] [-d] [-l] [-t] [-q] [-h] [-v]
DESCRIPTION
WAPG generates several random passwords. It uses several password gener-
ation 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 pass-
word. 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 (#,@,!,...).
Built-in pseudo random number generator is an implementation of algo-
rithm 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 precision of microseconds (see gettimeofday(2)) and /dev/random
(if available) to produce initial random seed.
WAPG also have the ability to check generated password quality using
dictionary. You can use this ability if you specify command-line
options -r dictfile or -b filtername where dictfile is the dictionary
file name and filtername is the name of Bloom filter file. In that dic-
tionary 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 dictionaries that come with dictionary password
crackers. Bloom filter file should be created with WAPGbfm(1) utility
included in WAPG distribution. These checks are case sensitive. For
example, if you want to reject word 'root', you should insert in dict-
file words: root, Root, RoOt, ... , ROOT. It is not the easiest way to
check password quality, but it is the most powerful way. In future
releases I plan to implement some other techniques to check passwords
(like pattern check) just to make life easier.
OPTIONS
-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 gen-
eration.
N generator must use numeral symbol set for every generated
password.
n generator should use numeral symbol set for password gen-
eration.
C generator must use capital symbol set for every generated
password.
c generator should use capital symbol set for password gen-
eration.
L generator must use small letters symbol set for every
generated password (always present if pronounceable pass-
word generation algorithm is used).
l generator should use small letters symbol set for pass-
word generation.
R,r not supported any more. Use -E char_string option
instead.
mode can not 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
-a algorithm
use algorithm for password generation.
0 - (default) pronounceable password generation
1 - random character password generation
-E char_string
exclude characters in char_string from password generation pro-
cess (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
char_string use the backslashed versions.
Examples:
Command WAPG -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 WAPG -a 1 -M nc -n 3 -m 26 -e GHIJKLMNOPQRSTUVWXYZ will
generate a set of passwords that will look like this
16A1653CD4DE5E7BD9584A3476
C8F78E06944AFD57FB9CB882BC
8C8DF37CD792D36D056BBD5002
-r dictfile
check generated passwords for their appearance in dictfile
-b filter_file
check generated passwords for their appearance in filter_file.
filter_file should be created with WAPGBFM utility.
-p min_substr_len
this option tells WAPG to check every substring of the gener-
ated password for appearance in filter_file. If any of such sub-
strings would be found in the filter_file then generated
password would be rejected and WAPG will generate another one.
min_substr_len specifies minimum substring length to check.
This option is active only if -b option is defined.
-c cl_seed
use cl_seed as a random seed for password generation. I use it
when i have to generate passwords in a shell script.
-d do NOT use any delimiters between generated passwords. I use it
when i have to generate passwords in a shell script.
-n num_of_pass
generate num_of_pass number of passwords. Default is 6.
-m min_pass_len
generate password with minimum length min_pass_len. If
min_pass_len > max_pass_len then max_pass_len = min_pass_len.
Default minimum password length is 8.
-x max_pass_len
generate password with maximum length max_pass_len. If
min_pass_len > max_pass_len then max_pass_len = min_pass_len.
Default maximum password length is 10.
-q quiet mode (do not print warnings)
-l spell genetated passwords. Useful when you want to read gener-
ated 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
WAPG -a 0 -M sncl -n 6 -x 10 -m 8 (new style)
EXIT CODE
On successful completion of its task, WAPG will complete with exit code
0. An exit code of -1 indicates an error occurred. Textual errors are
written to the standard error stream.
FILES
None.
BUGS
None. If you've found one, please send bug description to the author.

NAME
apg - generates several random passwords
SYNOPSIS
apg [-a algorithm] [-M mode] [-E char_string] [-n num_of_pass] [-m
min_pass_len] [-x max_pass_len] [-r dictfile] [-b filter_file] [-p
min_substr_len] [-c cl_seed] [-d] [-l] [-t] [-q] [-h] [-v]
DESCRIPTION
apg generates several random passwords. It uses several password gener-
ation 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 pass-
word. 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 (#,@,!,...).
Built-in pseudo random number generator is an implementation of algo-
rithm 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 precision of microseconds (see gettimeofday(2)) and /dev/random
(if available) to produce initial random seed.
apg also have the ability to check generated password quality using
dictionary. You can use this ability if you specify command-line
options -r dictfile or -b filtername where dictfile is the dictionary
file name and filtername is the name of Bloom filter file. In that dic-
tionary 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 dictionaries that come with dictionary password
crackers. Bloom filter file should be created with apgbfm(1) utility
included in apg distribution. In future releases I plan to implement
some other techniques to check passwords (like pattern check) just to
make life easier.
OPTIONS
Password generation modes options
-a algorithm
use algorithm for password generation.
0 - (default) pronounceable password generation
1 - random character password generation
-n num_of_pass
generate num_of_pass number of passwords. Default is 6.
-m min_pass_len
generate password with minimum length min_pass_len. If
min_pass_len > max_pass_len then max_pass_len = min_pass_len.
Default minimum password length is 8.
-x max_pass_len
generate password with maximum length max_pass_len. If
min_pass_len > max_pass_len then max_pass_len = min_pass_len.
Default maximum 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 gen-
eration.
N generator must use numeral symbol set for every generated
password.
n generator should use numeral symbol set for password gen-
eration.
C generator must use capital symbol set for every generated
password.
c generator should use capital symbol set for password gen-
eration.
L generator must use small letters symbol set for every
generated password (always present if pronounceable pass-
word generation algorithm is used).
l generator should use small letters symbol set for pass-
word generation.
R,r not supported any more. Use -E char_string option
instead.
mode can not 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 char_string
exclude characters in char_string from password generation pro-
cess (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
char_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
generate a set of passwords that will look like this
16A1653CD4DE5E7BD9584A3476
C8F78E06944AFD57FB9CB882BC
8C8DF37CD792D36D056BBD5002
Password quality control options
-r dictfile
check generated passwords for their appearance in dictfile
-b filter_file
check generated passwords for their appearance in filter_file.
filter_file should be created with apgbfm(1) utility.
-p min_substr_len
this option tells apg(1) to check every substring of the gener-
ated password for appearance in filter_file. If any of such sub-
strings would be found in the filter_file then generated pass-
word would be rejected and apg(1) will generate another one.
min_substr_len specifies minimum substring length to check.
This option is active only if -b option is defined.
Pseudo random number generator options
-c cl_seed
use cl_seed as a random seed for password generation. I use it
when i have to generate passwords in a shell script.
Password output options
-d do NOT use any delimiters between generated passwords. I use it
when i have to generate passwords in a shell script.
-q quiet mode (do not print warnings)
-l spell genetated passwords. Useful when you want to read gener-
ated 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 (new style)
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.
FILES
None.
BUGS
None. If you've found one, please send bug description to the author.

NAME
WAPGBFM - APG Bloom filter management program
SYNOPSIS
WAPGBFM -f filter -n numofwords [-q] [-s]
WAPGBFM -f filter -d dictfile [-q] [-s]
WAPGBFM -f filter -a word [-q]
WAPGBFM -f filter -A dictfile [-q]
WAPGBFM -f filter -c word [-q]
WAPGBFM -f filter -C dictfile [-q]
WAPGBFM -i filter
WAPGBFM [-v] [-h]
DESCRIPTION
WAPGBFM is used to manage Bloom filter that is used to restrict password
generation in WAPG pasword generation software. Usage of the Bloom fil-
ter allows to speed up password check for large dictionaries and has
some other benefits.
The idea to use Bloom filter for that purpose is came from the descrip-
tion of the OPUS project OPUS: Preventing Weak Password Choices Purdue
Technical Report CSD-TR 92-028 writen by Eugene H. Spafford.
You can obtain this article from:
http://www.cerias.purdue.edu/homes/spaf/tech-reps/9128.ps
It has very nice description of Bloom filter and it's advantages for
password checking systems.
In simple words, WAPGBFM generates n hash values for every word and sets
corresponding bits in filter file to 1. To check the word WAPGBFM gener-
ates the same hash functions for that word and if all n corresponding
bits in filter file are set to 1 then it suppose that word exists in
dicionary. WAPGBFM uses SHA-1 as a hash function.
WAPGBFM can be used as standalone utility, not only with apg, or apgd.
WARNING !!!
Filter file format can be changed in the future. I'll try to
make file formats compatible but i can not guaranty this.
WARNING !!!
WAPGBFM may slow down your computer during filter creation.
OPTIONS
-f filter
use filter as the name for Bloom filter filename.
-i filter
print information about filter.
-n numofwords
create new empty filter for numofwords number of words. Useful
when you want to fill filter dynamicaly.
-d dictfile
create new filter from dictfile. It may take a lot of time to
generate filter from a big dictionary. In that dictionary you
may place words (one per line) that should not appear as gener-
ated passwords. For example: user names common words, etc. You
even can use one of the dictionaries that come with dictionary
password crackers. This check is case sensitive. For example,
if you want to reject word 'root', you should insert in dictfile
words: root, Root, RoOt, ... , ROOT. To indicate that program
is working WAPGBFM prints dot for every 100 words added in dic-
tionary.
-a word
add word to the filter.
-A dictfile
add all words from dictfile to the filter. To indicate that pro-
gram is working WAPGBFM prints dot for every 100 words added in
dictionary.
-c word
check word for appearance in the filter.
-C dictfile
check every word from dictfile for appearance in the filter.
-q quiet mode.
-s create new filter in case-insensitive mode.
-v print version information.
-h print help information.
EXIT CODE
On successful completion of its task, WAPGBFM will complete with exit
code 0. An exit code of -1 indicates an error occurred. Textual
errors are written to the standard error stream.
FILES
None.
BUGS
None. If you've found one, please send bug description to the author.
