gpgme-2.0.1

Introduction to gpgme

The gpgme package is a C library that allows cryptography support to be added to a program. It is designed to make access to public key crypto engines like GnuPG or GpgSM easier for applications. gpgme provides a high-level crypto API for encryption, decryption, signing, signature verification and key management.
