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.\n\nSecurity Fix(es):\n\nBotan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings.
