What is "The OpenPGP Library"?
There is no single standard library for OpenPGP application programmers.
There are several implementations of the OpenPGP standard - gnupg being the
most commonly used, but there are many others for different languages and
platforms - Swift, Obj-C, Python, Java, Javascript, Rust, Go, etc. etc. The
maintainers of those libraries have to be trusted to get it right and
provide APIs that application developers can easily incorporate into the
program flow. Chunking is a departure from the traditional PGP message
processing and will involve significant changes to both existing libraries
and the applications that consume them.
