When I read I’m throwing in the towel on PGP, and I work in security, which appeared as an Op-ed in ArsTechnica, I felt that it certainly deserved a response. While makes some valid points about PGP/GPG, I felt that they were less about shortcomings in the scheme and rather usability issues that have been unfortunately ignored.
Then I read “Why I’m not giving up on PGP“, an excellent article, also in ArsTechnica, and it does a much better job of refuting the article than I could ever have done.
Both are well worth the read.
