The iProcess Encryption Layer Object The following encryption objects are provided in the SDK so that you can create replacement UVAPI packages: • uvapienc.obj - for Windows 2003/XP • uvapienc.o - for UNIX Text strings passed across the UVAPI are encrypted using a proprietary TIBCO mechanism. You need to use this object when implementing a new UVAPI package to provide the encryption/decryption of parameter strings.
