- 20070115: uploaded gnupg dif. I did an audit of gnupg, and Werner Koch (gnupg author) wasn't particularly helpful or interested, so here is my private diff. Note: I don't claim that all of the changes are exploitable security issues. Since I'm only human, too, I would appreciate others to go over the gnupg source code and my diff as well.
