Class MetaDataConverter

  extended by com.adobe.flashaccess.sdk.compatibility.MetaDataConverter

public class MetaDataConverter
extends java.lang.Object

This class is used to convert FMRMS 1.x format metadata to Flash Access 2.0 format. When a Flash Access 2.0 client encounters 1.x content, the 1.x encryption metadata will be sent to the server to be converted to 2.0 format. This conversion can be done on-demand, or the metadata can be converted in advance by extracting the metadata from packaged files, doing the conversion, and storing the updated metadata on the server. When a client request arrives, the server can use the license ID to match the request with the converted metadata and send the stored result.

Conversion Workflow:

To convert metadata, perform the following steps:

  1. Get LiveCycleKeyMetaData from either FMRMSv1MetadataHandler or MediaEncrypter.examineEncryptedContent()
  2. Get license ID from LiveCycleKeyMetaData, and find the encryption key and policies. (This info was originally in the LiveCycle database. The LiveCycle policies need to be converted to Flash Access 2.0 Policies.)
  3. Fill in V2KeyParameters (Use MediaEncrypter.createKeyParameters() to get the parameters object.)
  4. Load ServerCredential, the License Server credential issued by Adobe, used to sign encryption metadata. Get SignatureParameters from MediaEncrypter.createSignatureParameters() and fill in the server credential.
  5. Call convertMetadata() to obtain V2ContentMetaData
  6. Call V2ContentMetaData.getBytes() and either pass the bytes to FMRMSv1MetadataHandler or store for future use.
