security/botan2 2.19.5p2 OpenBSD

Botan (Japanese for peony) is a cryptography library written in C++11 and released under the permissive Simplified BSD license. Botan's goal is to be the best option for cryptography in new C++ code by offering the tools necessary to implement a range of practical systems, such as TLS/DTLS, PKIX certificate handling, PKCS#11 and TPM hardware support, password hashing, and post quantum crypto schemes. In addition to the C++, botan has a C89 API specifically designed to be easy to call from other languages. A Python binding using ctypes calling the C89 API is included.
