I am who you believe I am.
Ever since I (somewhat) learned how the GnuPG web of trust and private/public key crypto and key management systems work, I've been fascinated with this topic. I wish more people use them for their email and online identity management.
This week I set up an Ubuntu desktop at work. GnuPG integrates very well with Linux; however, there are also tools that work well with Windows such as gpg4win. Try installing gpg4win without Kleopatra. The Gnu Privacy Assistant (GPA) works well enough for me.
