How to verify whether the encrypted rbf generated by the qcrypt tool can be decrypted correctly？
Now I use the development board of cyclone10gx, How to verify whether the encrypted rbf generated by the qcrypt tool can be decrypted correctly？

Regular ContributorAre you saying that you want to evaluate whether the encrypted RBF using decrypt tool is valid or not? If so, i think you may start with non-volatile key first. If it is working then only change to volatile key as volatile key is none reversable.
Thank you for your reply.
Sorry, let me elaborate. Proceed as follows
1. Generate the ekp file with Quartus Prime Convert Programming File.
2. Use the Quartus Programmer tool to program the ekp into the FPGA.
3. The encrypted rbf generated by sof using the Quartus Prime Convert Programming File can configure the FPGA.
4. After using the Quartus Prime Convert Programming File to generate the unencrypted rbf from sof, the encrypted rbf generated from the unencrypted rbf using the qcrypt tool cannot configure the FPGA.The command used is as follows,
qcrypt.exe -e --keyfile=keyfile.key --keyname=key1 --keystore=battery unencrypted.rbf encrypted_byQcrypt.rbf
I would like to know how to use the qcrypt tool in detail, to troubleshoot what went wrong, and look forward to your reply. thanks
