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.
