Oracle Taleo is deprecating the use of the SHA-1 hashing function. As part of this project, the Oracle Taleo zone certificate will be upgraded to SHA-2, replacing the current SHA-1 certificate. Accordingly, the TCC client must be updated to utilize a SHA-2 certificate.
The SHA-2 compatible TCC version has been released. It is available for download from Oracle e-Delivery site. Customers must download and install no later than September 30, 2016. We have created a guide for customers who are using Taleo Connect Client (TCC) to integrate with their instance of Oracle Taleo Enterprise Edition Cloud Service. Please navigate to the Customer Connect “Taleo Transition to SHA-2”here for the guide with TCC migration requirement and next steps.
