This article presents GnuPGWrapper v1.0, a wrapper class for GnuPG. GnuPG is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC 2440. As such, GnuPG is a complete and free replacement for PGP (Pretty Good Privacy).
