SecureBlackbox product diagram

PKI (Public Key Infrastructure) is a set of technologies, that utilize asymmetric cryptography for signing and encryption of sensitive data, and for authentication of various entities, such as web servers, individuals and organizations. One of the most important parts of PKI are X.509 certificates (also incorrectly called SSL certificates) which "certify" authenticity of the person or software, which presents the certificate. The certificates are also used for signing and encryption of data.

PKIBlackbox (.NET edition, part of SecureBlackbox software product) is a collection of managed components for PKI support in your C#, VB.NET, C++.NET, ASP.NET applications.
