Created June 29, 2013 22:48
I am currently reviewing Go's OpenPGP implementation with a view of possibly implementing bzip2 support for it, as well as testing compatibility with GNUPG. This is a simple GIST that shows how to decrypt a symmetrically encrypted file using go.crypto/openpgp. It can be useful for testing go.crypto/openpgp compatibility with various symmetric ci…

In this gist, the remote SSH server is on localhost and the HTTP URL tunneled over the established secure connection is http://localhost:6060. But,…
