We're sending the spcData payload to our fairplay key server (version 5.1) with the base64 encoded string of our fairPlay.cer that was downloaded from our developer portal and we're getting a spcVersionErr (-42580) for the spc version. The value that is being received by the key server seems to be 813827283 when it should be either 1 (base_constants.SPCVersion.v1.rawValue) or 2 (base_constant.SPCVersion.v2.rawValue). We're assuming we're encoding the fairplay.cer incorrectly. Any insight from anybody would be appreciated.
