What is a package?

SecureBlackbox includes a number of components that help you solve various digital security tasks. A package in SecureBlackbox is a group of components, which are used for the one or several similar functions. For example, PKIBlackbox package includes components to work with X.509 certificates, certificate storages etc. .

Some packages include one or several other packages. For example, XMLBlackbox includes components for XML security and also includes OpenPGPBlackbox package, which provides components for OpenPGP standard.
