Werner Koch, the man who authored the free email encryption software, is running out of funding to continue the development of his crucial open-source Gnu Privacy Guard (GnuPG) encryption tools. Koch has been maintaining and improving the code of his own secure email software since its initial development in 1997, and since then he has worked at very low wages. Koch was about to quit the project in 2013 because from past three years the funding for the project has been evaporating. But meanwhile, Snowden revelations once again boosted him up. The software is the same used by the former U.S. National Security Agency contractor Edward Snowden to keep his communication secure from law enforcement authorities.
