-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 generation.

N

generator must use numeral symbol set for every generated password.

n

generator should use numeral symbol set for password generation.

C

generator must use capital symbol set for every generated password.

c

generator should use capital symbol set for password generation.

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.

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 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 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

-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 generated password 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(1) will generate another one. min_substr_len specifies minimum substring length to check. This option is active only if -b option is defined.

-s

ask user for random sequence for password generation

-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.

-y

print generated passwords and crypted passwords (see man crypt(3))

-q

quiet mode (do not print warnings)

-l

spell genetated 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
