Options:
-a ALGORITH Choose the password generation algorithm (Default: 1)
- 0: pronounceable password generation (koremutake syllables)
- 1: random password generation according to password modes/flags
-m LENGTH Minimum length of the password to be generated (Default: 12)
-x LENGTH Maximum length of the password to be generated (Default: 20)
-n NUMBER Amount of password to be generated (Default: 6)
-E CHARS List of characters to be excluded in the generated password
-M [LUNSHClunshc] New style password parameters (upper case: on, lower case: off)
-L Use lower case characters in passwords (Default: on)
-U Use upper case characters in passwords (Default: on)
-N Use numeric characters in passwords (Default: on)
-S Use special characters in passwords (Default: off)
-H Avoid ambiguous characters in passwords (i. e.: 1, l, I, O, 0) (Default: off)
-C Enable complex password mode (implies -L -U -N -S and disables -H) (Default: off)
-l Spell generated passwords in phonetic alphabet (Default: off)
-p Check the HIBP database if the generated passwords was found in a leak before (Default: off)
