You can generate Expressplay tokens for their encrypted content by sending token requests to the appropriate Expressplay token server.
An example is the following URL:
https://wv-gen.service.expressplay.com/hms/wv/
token?customerAuthenticator=<your expressplay customer authenticator>
&kid=fd1a706ac2b36002888f6d4a414333c3
&contentKey=5438b719bf47a2f5678237477db2f9e6
&securityLevel=1
&hdcpOutputControl=0
The content encryption key storage ID or CEKSID given to the kid
parameter and the content encryption key or CEK given to the contentKey
parameter must match the content encryption key storage ID and content encryption key used for packaging. The following text is an example of the token server response:
https://wv.service.expressplay.com/hms/wv/rights/
?ExpressPlayToken=AQAAABIDKbgAAABQbt68jktab0YRY-r9mo6VP
