(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. Bug: 186782279 Test: x86-64 platform Test: opk_ta platform Test: build_and_run_all_unit_tests Change-Id: I15156882907b0987215087aaf43b4666fedc171a
