OpenPGP is an Internet Engineering Task Force (IETF) ratified standard based around PGP 5, which Hush and Zimmermann hope will become a global standard as the public demand for secure communications increases. OpenPGP as a development platform can be used to develop email encryption as well as roll out digital signatures and key management systems, said Zimmermann.
PGP 5 is guaranteed free of backdoors after being "developed on my watch", said Zimmermann. A point of contention between the cryptographer and the now-owners of PGP, Network Associates, was that his previous employers refused to publish the PGP source code. Hush, however, does publish the source code for both its previous encryption product and OpenPGP.
