Detailed Description

Botan is released under the Simplified BSD License (see license.txt)

Ordinary applications should never need to include or use this header. It is exposed only for specialized applications which want to implement new versions of public key crypto without merging them as changes to the library. One actual example of such usage is an application which creates RSA signatures using a custom TPM library. Unless you're doing something like that, you don't need anything here. Instead use pubkey.h which wraps these types safely and provides a stable application-oriented API.
