I forgot one of my email passwords. And it's still saved in Thunderbird that ran on Kubuntu. But now my Kubuntu is broken, and I cannot open thunderbird's GUI. The only thing I know is username and password I used to open a new session on my broken Kubuntu installation. Anyway. So I tried hacking the file signons.sqlite containing my passwords, using this tutorial on stackexchange.
I could follow all the steps of the tutorial, except of the last one. And since it's not allowed on stackexchange to ask extra questions with low reputation, I am writing it here.
echo "select encryptedUsername, encryptedPassword from moz_logins;" | sqlite3 ~/.thunderbird/*.default/signons.sqlite
So where in the integer string can I find the encrypted Username and Password? And how to use Kubuntu's username+password to simply decrypt my email login credentials? I don't want to use Thunderbird Password Decryptor, because I distrust this hacking software.
