d7b377f976 Add the OEMCrypto test RSA key in DER format
Merge from Widevine repo of http://go/wvgerrit/125744

The OEMCrypto tests use a fixed RSA key.  This will be loaded using
OEMCrypto_LoadTestRSAKey.  This adds that key in DER format. This key
was stored in the kTestRSAPKCS8PrivateKeyInfo2_2048 variable in the
code.

This variable was written to, but the value was never read. Newer

in the CL http://go/wvgerrit/131303.

This splits the clock interface into two layers so that we can save

Refactor dynamic adapter keybox verification

Merge from Widevine repo of http://go/wvgerrit/133727
http://go/ag/14812524

The keybox validation needs to be done separately from initializing
the library so that we can support Keybox OTA Reprovisioning.

If L1 loads, but the keybox is missing, the initialization should
succeed. When the keybox is validated, the adapter should try to look
for a keybox on the filesystem. if none is found, it should either
return NEEDS PROVISIONING or an error.

Update crypto session to use new OTA keybox functionality

This CL stubs out two new CryptoSession functions that call the new

It also adds a boolean needs_keybox_provisioning that is set to true
when OEMCrypto reports that it needs a keybox. This should only happen
if there is no keybox installed and oemcrypto supports provisioning.

68187b9f02 Fix -Wshorten-64-to-32 errors in BoringSSL interactions
(This is a merge from the Widevine Repo of http://go/wvgerrit/134310.)

This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. The cause of most
of these is that OpenSSL uses "int" for the length of things rather than
size_t. (While BoringSSL sometimes uses int and sometimes uses size_t.)

One exception is LogBoringSSLError(). We have a couple copies of this
function around, and they varied slightly. This patch brings them all
in-line, which conveniently also removes any code in them that would
deal with integer variables.

GetRandBytes() now takes a size_t and downcasts to BoringSSL's native
int internally, so that callers can pass in a size_t value as they would
expect.

There's also an interesting case in oec_session_util.cpp. Because
BoringSSL and OpenSSL disagree about the width of an error code, we have
to use the "auto" type for a temporary variable that holds an error, in
order to retain compatibility with both.

052016eb57 Add extra RSA private keys to unit tests
Merge from Widevine repo of http://go/wvgerrit/128047

There have been some failures with various RSA private keys. We add
them to the unit tests to make sure that OEMCrypto is able to load
these types of keys:
* Shorter: than normal private exponents. This seems to occur
  occasionally even with Euler totients. But it occurs more with
  Carmichael totients.
* 0-leading-byte: private exponents. This also occurs naturally for
  both Euler and Carmichael totients.
* Carmichael: vs Euler totients. I think we may already have tests for
  this. But just in case.

d742daf9c7 Validate decryption with entitled keys in OEC tests
(This change is merged from http://go/wvgerrit/124825)

The OEMCrypto tests have tests that verify that entitled keys can be
loaded but not that they can be successfully used for decrypt. This
patch adds a decrypt portion to the existing tests.

As part of this, the existing Session::EncryptCTR() method and portions
of Session::TestDecryptCTR() are lifted to be static functions so they
can be shared across unrelated classes in oec_session_util.cpp.
EncryptCTR() had no dependence on its enclosing class and is unchanged
other than being moved outside the class.

To reduce ambiguity with the new decrypt verification, this patch also
renames EntitledMessage::VerifyEntitlementTestKeys() to the
more-specific EntitledMessage::VerifyKCBs(). Its behavior is unchanged.

ed17d09c1b Remove asserts from GenerateSimpleSampleDescription()
(This change is merged from http://go/wvgerrit/124824)

GenerateSimpleSampleDescription() only had asserts to check parameters
that only came from other test code, so they weren't testing anything of
use. With the asserts removed, it's no longer necessary to wrap calls to
GenerateSimpleSampleDescription() with ASSERT_NO_FATAL_FAILURE(), which
a lot of callers were already forgetting to do anyway. This also
simplifies a future patch that will generalize the decryption test code
to work with entitlement licenses.
