From 4793624c65673268128fb0146cd9bd1b3cfeb6c4 Mon Sep 17 00:00:00 2001 From: Jameson Graef Rollins Date: Tue, 10 Jun 2008 17:17:51 -0400 Subject: New client/server components: - broke out all common functions to "common" file - put all client commands into "monkeysphere" script - put all server commands into "monkeysphere-server" script - moved all code into src directory to clean things up a bit - this effectively makes obsolete rhesus and howler - added proposed monkeysphere-ssh-proxycommand script that can be called to update known_hosts from ssh ProxyCommand - updated monkeysphere.conf to work as global client config - added monkeysphere-server.conf for server config --- src/gpg2ssh/gnutls-helpers.h | 72 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 src/gpg2ssh/gnutls-helpers.h (limited to 'src/gpg2ssh/gnutls-helpers.h') diff --git a/src/gpg2ssh/gnutls-helpers.h b/src/gpg2ssh/gnutls-helpers.h new file mode 100644 index 0000000..9ea22a3 --- /dev/null +++ b/src/gpg2ssh/gnutls-helpers.h @@ -0,0 +1,72 @@ +/* Author: Daniel Kahn Gillmor */ +/* Date: Fri, 04 Apr 2008 19:31:16 -0400 */ +/* License: GPL v3 or later */ + + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +/* Functions to help dealing with GnuTLS for monkeysphere key + translation projects: */ + +/* set everything up, including logging levels.
