Cryptography Toolkit
Botan is a C++ cryptography library released under the permissive
Simplified BSD <https://botan.randombit.net/license.txt>_ license.
Botan's goal <https://botan.randombit.net/handbook/goals.html>_
is to be the best option for production cryptography by offering the tools
necessary to implement a range of practical systems, such as TLSv1.3, X.509 PKI,
modern AEAD ciphers, support for PKCS#11 and TPM hardware, memory-hard password
hashing, and post quantum cryptography. All of this is covered by an extensive
test suite, including an automated system for detecting side channels. The
modular build system allows enabling or disabling features in a fine-grained way,
and amalgamation builds are also supported.
It comes out of the box with C++, C, and Python APIs, and several other language bindings <https://github.com/randombit/botan/wiki/Language-Bindings>_ are available.
The library is accompanied by a featureful command line interface <https://botan.randombit.net/handbook/cli.html>. Consult the documentation <https://botan.randombit.net/handbook> for more information.
Development is coordinated on GitHub <https://github.com/randombit/botan>__ and
contributions are welcome. If you need help, please open an issue on GitHub <https://github.com/randombit/botan/issues>_. If you think you have found a
security issue, see the security page <https://botan.randombit.net/security.html>
