CryptNET Password Generator



<passgen> − A password candidate generator


passgen [options]

options: [-aAChHlLNrsuUv] [--help] [--version]


passgen generates a list of password candidates for the user to choose from by mapping operating system sources of pseudorandomness into printable character arrays with a mod operation.

By default, /dev/random is used as the source for entropy. If a large number of password candidates are being generated the process may be slowed while the device blocks. This can avoided by using the -u flag, which will cause the nonblocking urandom device as the entropy source.



Generate password candidates alpha numeric characters only.


Generate password candidates using alphabetic characters only.


Suppress config file not found message.


Displays help text.


Homoglyph suppression level (0-2)

0 − No homoglyph suppression.
1 − Suppress font homoglyphs such as zero, capital ’o’ (oscar), one, and lowercase ’l’ (lema).
