I've been trying to find a good explanation on how something like gpg -r DEADBEEF -r CAFEBABE -r 8BADFOOD -o output.gpg -e input.txt works. The best I've been able to find is this: http://lists.gnupg.org/pipermail/gnupg-users/2007-October/031938.html I'm mostly interested in the overhead, so

Hi, is there any plan to include post-quantum cryptography ciphers such as McEliece and NTRU in GnuPG? I know that NTRU is patented until 2020, but I found some C implementations. It says that modifying the code it is possibile to have it patent-free in 2017. http://goo.gl/cQGavW This is there o
