## Reference OEMCrypto Implementation

The CE CDM requires an implementation of OEMCrypto, our hardware abstraction
layer, in order to compile and run successfully. To facilitate testing and
development, a test-only software implementation of OEMCrypto is included in
the `oemcrypto/ref/` directory. The CE CDM links against this version of
OEMCrypto by default. **This implementation is *NOT* suitable for production use
and should *NOT* be released on devices.** It is included only so you can
compile and test the CE CDM on your platform before your own implementation of
OEMCrypto is ready.
