Password generator implementation in C

The title is very self-explanatory, tbh.

Build

Usage

./passgen <<< <how many characters> <<< <difficulty level: 0 or 1 or 2> | tail -n 1

Example:

./passgen <<< 10 <<< 2 | tail -n 1

You can pipe the result to your clipboard using xclip or similar tools like so:

./passgen <<< 10 <<< 2 | tail -n 1 | xclip -selection clipboard

You can these useful aliases to make copying and pasting in CLI easier.
(At the end of your ~/.bashrc file):

# Copy to the clipboard
alias c='xclip -selection clipboard'
# Paste from the clipboard
alias p='xclip -selection clipboard -o'

# Navigate to the string path in the clipboard 
alias cdp='cd "$(p)"'

Hence the example could be simplified by running:

./passgen <<< 10 <<< 2 | tail -n 1 | c

You can even add an alias that runs this whole command for whenever you need to generate a new password for a random website.

alias genpass='/path/to/passgen <<< 10 <<< 2 | tail -n 1 | c'
