signatures.
This library has no pre-requisites other than -lz and -lbz2.
This is libnetpgpverify, a standalone library to verify PGP
signatures.
It uses its own internal MPI/BIGNUM functions, which are a vastly
cut-down version of libtommath. For this reason, utilities and other
libraries can embed PGP signature verification, using a BSD-licensed
library.
