Notes about the OTRKEY file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The OTRKEY file type is primarily associated with 'OnlineTvRecorder' by OnlineTvRecorder.com. Some German TV programs can be sent to specific users requesting them. The program is encrypted and sent as an .OTRKEY file which can only be decrypted by the specific user requesting the program. There is some thought that the encryption is some form of the Blowfish technique.
