At first sight I cannot see any particular added feature this (nice) program has (apart it being Open Source), when compared to old tools, like the Nirsoft one:<p><a href="https://www.nirsoft.net/utils/wireless_key.html" rel="nofollow">https://www.nirsoft.net/utils/wireless_key.html</a><p>though having an aternative is always a good thing.<p>A 74 KB portable program seems to me a lot more practical than a 4 MB setup/install, when/if you need to recover a password.
