Botan: Crypto and TLS for C++11
========================================
Botan (Japanese for peony) is a cryptography library written in C++11
and released under the permissive `Simplified BSD
<https://botan.randombit.net/license.txt>`_ license.
Botan's goal is to be the best option for cryptography in C++ by offering the
tools necessary to implement a range of practical systems, such as TLS/DTLS,
X.509 certificates, modern AEAD ciphers, PKCS#11 and TPM hardware support,
password hashing, and post quantum crypto schemes. Botan also has a C89 API
specifically designed to be easy to call from other languages. A Python binding
using ctypes is included, and several other `language bindings
<https://github.com/randombit/botan/wiki/Language-Bindings>`_ are available.
Find the full feature list below.
Development is coordinated on `GitHub <https://github.com/randombit/botan>`_
and contributions are welcome (read ``doc/contributing.rst`` for more info).
If you need help with a problem, please open an `issue on GitHub
<https://github.com/randombit/botan/issues>`_ or email the
`botan-devel mailing list
<https://lists.randombit.net/mailman/listinfo/botan-devel/>`_.
New releases are announced on the
`botan-announce mailing list
<https://lists.randombit.net/mailman/listinfo/botan-announce/>`_.
If you think you have found a security bug in Botan please contact
Jack Lloyd by emailing jack@randombit.net. His PGP public key with
fingerprint 4E60C73551AF2188DF0A5A6278E9804357123B60 can can be found
in ``doc/pgpkey.txt`` in the distribution,
https://keybase.io/jacklloyd, and some public PGP key servers.

For all the details on building the library, read the
`users manual <https://botan.randombit.net/manual>`_, but basically::
$ ./configure.py
$ make
$ ./botan-test
...
$ make install
Botan can also be built into a single-file amalgamation for easy inclusion into
external build systems, see the manual for details.

Release Downloads
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
See the `release notes <https://botan.randombit.net/news.html>`_ and
`security advisories <https://botan.randombit.net/security.html>`_
All releases are signed with a
`PGP key <https://botan.randombit.net/pgpkey.txt>`_::

uid Botan Distribution Key
Some `distributions <https://github.com/randombit/botan/wiki/Distros>`_
such as Arch, Fedora and Debian include packages for Botan. However
these are often out of date; using the latest source release is recommended.
Current Stable Release
----------------------------------------
Version 2 requires a C++11 compiler; GCC 4.8 and later, Clang 3.8 and later, and
MSVC 2015/2017 are regularly tested. New releases of Botan 2 are made on a
quarterly basis.
The latest 2.x release is
`2.7.0 <https://botan.randombit.net/releases/Botan-2.7.0.tgz>`_
`(sig) <https://botan.randombit.net/releases/Botan-2.7.0.tgz.asc>`_
released on 2018-07-02
Old Release
----------------------------------------
The 1.10 branch is the last version of the library written in C++98. It is no
longer supported except for critical security updates (with all support ending
in December 2018), and the developers do not recommend its use anymore.
The latest 1.10 release is
`1.10.17 <https://botan.randombit.net/releases/Botan-1.10.17.tgz>`_
`(sig) <https://botan.randombit.net/releases/Botan-1.10.17.tgz.asc>`_
