strongpw

Helper script to create strong passwords.

Default minimum length are 12 characters based on

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
0123456789
!" #$%&\'()*+,-./:;<=>?@[\\]^_`{|}~

Example

Create a strong password with a default length of 12 characters.

$ strongpw
Eisv&<*U\] B

Same, but disallow certain characters, e.g. space, asterisk and plus:

$ strongpw -d ' *+'
&'wZ4PtRh&SC

Create a stronger 20 character password:

$ strongpw 20 
wDt!P.6O~}H9vY@`P(2j

Create a not so strong password most services will accept:

$ strongpw 20 --no-punctuation
gNQAGzAmxCWj77a4QZI

Same but verify the generated password has not been pwned as far as the haveibeenpwned service can tell:

$ strongpw --no-punctuation --check-pwned -l 20
lTRJdsCIXm7YZq26PWRO

Create a given number of passwords with a defined length:

$ strongpw -r 20 -l 16
QFEB.*t\![ncvtH`WN{]Jy?"`I(Cbk

...

Create a password based on a given alphabet (target):

$ strongpw -t hosteurope_ssh
h62pn;WGNpm^

This is currently rather an implementation idea as alphabets for passwords should usually not be restricted. Might be rather rare nower days.

List the available targets:

$ strongpw --list-targets
hosteurope_ssh
test_weak_alphabet
