A Python wrapper that encapsulates wolfSSL's wolfCrypt API.

wolfcrypt: the wolfSSL Crypto Engine

wolfCrypt Python, a.k.a. wolfcrypt is a Python module that encapsulates wolfSSL's wolfCrypt API.

wolfCrypt is a lightweight, portable, C-language-based crypto library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. It is the crypto engine behind wolfSSl's embedded ssl library.

Installation

We provide Python wheels (prebuilt binaries) for OSX 64 bits and Linux 64 bits:

$ pip install wolfcrypt

To build wolfcrypt-py against a local installation of the native C wolfSSL library, use the USE_LOCAL_WOLFSSL variable. This variable should be

wolfcrypt-py can be built against a local version of the native wolfSSL library by using pip with the USE_LOCAL_WOLFSSL variable. USE_LOCAL_WOLFSSL should be set equal to the installation path for the wolfSSL library:

$ USE_LOCAL_WOLFSSL=/path/to/wolfssl/install pip install .

If building wolfcrypt-py against a local wolfSSL library, wolfcrypt-py will attempt to do native feature detection to enable/disable wolfcrypt-py features based on how native wolfSSL has been compiled. It uses the <wolfssl/options.h> header to do feature detection.
