%description
Botan is a BSD-licensed crypto library written in C++. It provides a
wide variety of basic cryptographic algorithms, X.509 certificates and
CRLs, PKCS \#10 certificate requests, a filter/pipe message processing
system, and a wide variety of other features, all written in portable
C++. The API reference, tutorial, and examples may help impart the
flavor of the library. This is the current stable release branch 2.x
of Botan.
