    Welcome to botan-bindings

    Raw bindings to the [Botan](https://botan.randombit.net/) cryptography library.

    > 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 protocol,
    > X.509 certificates, modern AEAD ciphers, PKCS#11 and TPM hardware support,
    > password hashing, and post quantum crypto schemes.

    For more information, see the [README on Github](https://github.com/apotheca/botan)
