User Crypto Modules

wolfSSL has a new feature to allow for users to plug in their own crypto for RSA if they so choose. This is a great feature for students looking to test their own RSA operations in a SSL/TLS connection or for those wanting to see if they can speed up operations in the IoT realm and on embedded devices. This option can be used with the build flag “–with-user-crypto”. An example of building a module can be found in the directory “wolfssl_root/wolfcrypt/user-crypto/” and built with the commands:

cd wolfcrypt/user-crypto/
sudo make install

This example makes use of Intel’s IPP libraries and needs them installed and existing on the system before being able to build. For any questions on use, or about the wolfSSL embedded SSL/TLS library in general, contact us at
