OEMCrypto v15.1 Updates

Browse Source

This CL updates documentation, reference code, and unit tests to match
the OEMCrypto v15.1 API.

1. The design for the Full Decrypt Path Testing application has
changed. Instead of reading hashes from an external file, it will use
a single key frame and modify it to match the desired size.  The test
application will then compute the hash and encrypt the frame.  For
OEMCrypto, this means that there will not be a call to
OEMCrypto_InitializeDecryptHash before the frame and
OEMCrypto_SetDecryptHash after the frame. Instead, there will be a
single call to OEMCrypto_SetDecryptHash before the frame. The function
OEMCrypto_InitializeDecryptHash will not be used.

2. The "Shared License" feature is not used by any production
server. This functionality is no longer required and OEMCrypto may
reject licenses with a nonzero bit 23 in the key control block.
