It all depends on the method of removal. One (poor) method of removal would be simply deleting the ~/.gnupg/secring.gpg file, in which case recovery might be possible. Using wipe or shred would be better, and if either of those were used recovery is very unlikely. I don't know the method GPG uses internally to remove a secret key from the local secret keyring -- that's a good question. It would be good to know if that were some kind of secure removal. [Because I don't know, I don't count on it being a secure removal.] -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org https://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) Vassar College Apr 2 - Nginx: High-Performance HTTP Server, Reverse Proxy, and IMAP/POP3 Proxy Server May 7 - Google App Engine Jun 4 - Samba: Can We All Just Get Along?
