libpv is a collection of definitions and functions related to Protected Virtualization (PV). The functions cover mainly encryption (e.g. AES-GCM) and certificates (X509). There are also helping functions for glib2. Most of the code is extracted+refactored from `genprotimg`, which will use this library in future. Requires openssl v1.1.1+, glib2.56+, and libcurl. libpv is not designed or intended to be dynamically linked or used outside of this project. Its purpose is to avoid code duplication as PV tools do very similar things regarding cryptography.
