 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 precision of microseconds (see gettimeofday(2)) and /dev/random (if available) to produce initial random seed. 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.

-''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 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 dictionaries 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 passwords (like pattern check) just to make life easier.+''apg'' also have the ability to check generated password quality using dictionary.
