------------- Add libcurl to media_cas_packager_sdk. libcurl will later be used by a key fetcher to retrieve entitlement key from License Server using a HTTP request. ------------- Add a function named parsehelper to parse DCSL from the key smith response. ------------- Move wv_cas_key_fetcher to media_cas_packager_sdk so partners can use it request entitlement keys from License Server. ------------- Add pkcs7 write method to x509_cert.cc ------------- Update boringssl_repo to latest in master-with-bazel ------------- Add a TsPacket class to media_cas_packager_sdk to allow the construction of a ECM TS packet in the SDK. ------------- Move InsertEcm() from our internal CAS directory to the media_cas_packager_sdk, to be used to build a ECM TS packet by the SDK. ------------- Add METADATA in common folder ------------- Refactoring of certificate verification into DrmRootCertificate. ------------- Extend the default duration of leaf certificates. ------------- Fix moe_test ------------- Add a new method to WvCasEcm to allow partner to create a TS packet carrying the generated ECM. ------------- Change from SHA1 to SHA256 for Cast certificates ------------- Update crypto mode enumeration to match WV ECM document ------------- Fix the way we set the validity dates ------------- Move exported_root/util/status to common/ to prepare for util::Status migration Also added constructor/operator to copy from/to util::Status. ------------- Add GenerateDCSLrequest function to certificate_util.h. ------------- Fix build break ------------- Allow 'table_id' (in the section header) be specified by caller of SDK method WvCasEcm::GenerateTsPacket(). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=224535399
