apg generates several random passwords. It uses several password generation
|
|
|
|
|
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 password. 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 (#, at ,!,...).
|
|
|
|
|
|
|
|
|
|
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 preci-
|
|
|
|
|
sion of microseconds and random device (if available) to produce initial
|
|
|
|
|
random seed.
