> pwgen.sh #! /bin/sh /usr/local/bin/apg -m 8 -x 12 -s -> pwgen.sh EXIT CODE Usage, you can write a small shell script. If you want to generate really secure passwords, you should use option -s. t print pronunciation for generated pronounceable passwordĭEFAULT OPTIONS apg -a 0 -M sncl -n 6 -x 10 -m 8 (new style)

UBUNTU PWGEN PASSWORD

WARNING: Think twice before read your password by phone. Useful when you want to read generated password by y print generated passwords and crypted passwords (see man crypt(3)) Password output options -d do NOT use any delimiters between generated passwords. Use cl_seed as a random seed for password generation.

Pseudo random number generator options -s ask user for random sequence for password generation Option is active only if -b option is defined. min_substr_len specifies minimum substring length to check. If any of such substrings would be found in theįilter_file then generated password would be rejected and apg(1) will generateĪnother one. This option tells apg(1) to check every substring of the generated password forĪppearance in filter_file. Sign, etc.) in char_string use the backslashed versions.Ĭommand apg -a 1 -M n -n 3 -m 8 -E 23456789 will generate a set of passwords thatĬommand apg -a 1 -M nc -n 3 -m 26 -E GHIJKLMNOPQRSTUVWXYZ will generate a set ofġ6A1653CD4DE5E7BD9584A3476 C8F78E06944AFD57FB9CB882BC 8C8DF37CD792D36D056BBD5002 Password quality control options -r dictfileĬheck generated passwords for their appearance in dictfile -b filter_fileĬheck generated passwords for their appearance in filter_file. Include special symbols that can be recognized by shell (apostrophe, quotes, dollar Pronounceable password generation mode you can not exclude small letters). Usage of L, M, N, C will slow down password generation process.Įxamples: -M sncl or -M SNCL or -M Cn -E char_stringĮxclude characters in char_string from password generation process (in Mode can not be more than 4 characters in length. L generator should use small letters symbol set for password generation. (always present if pronounceable password generation algorithm is used). L generator must use small letters symbol set for every generated password N generator should use numeral symbol set for password generation.Ĭ generator must use capital symbol set for every generated password.Ĭ generator should use capital symbol set for password generation. N generator must use numeral symbol set for every generated password. S generator should use special symbol set for password generation. S generator must use special symbol set for every generated password. mode is a text stringĬonsisting of characters S, s, N, n, C, c, L, l. Use symbolsets specified with mode for password generation. Generate password with maximum length max_pass_len. Generate password with minimum length min_pass_len. Generate num_of_pass number of passwords. OPTIONS Password generation modes options -a algorithmĠ - (default) pronounceable password generation Implement some other techniques to check passwords (like pattern check) just to make life Bloom filter file should beĬreated with apgbfm(1) utility included in apg distribution. You even can use one of theĭictionaries that come with dictionary password crackers. For example: user names, common words, etc. That dictionary you may place words (one per line) that should not appear as generated Use this ability if you specify command-line options -r dictfile or -b filtername whereĭictfile is the dictionary file name and filtername is the name of Bloom filter file. dev/random (if available) to produce initial random seed.Īpg also have the ability to check generated password quality using dictionary. It uses local time with precision of microseconds (see gettimeofday(2)) and Symbols symbol set pseudo random number generator is an implementation of algorithm described inĪppendix C of ANSI X9.17 or RFC1750 with exception that it uses CAST or SHA-1 instead of

Symbol sets are: numeric symbol set (0.,9) ,Ĭapital letters symbol set (A.,Z), small letters symbol set (a.,z) and special Put online, so I have to use NIST implementation described in FIPS-181.Īnother algorithm is simple random character generation algorithm, but it uses four user-ĭefined symbol sets to produce random password. The original paper is very old and had never been (currently two) and a built-in pseudo random number generator.ĭefault algorithm is pronounceable password generation algorithm designed by Morrie GasserĪnd described in A Random Word Generator For Pronounceable Passwords National Technical Information Service (NTIS) AD-A-017676. It uses several password generation algorithms SYNOPSIS apg ĭESCRIPTION apg generates several random passwords.
