Hi,I am migrating my project from Xcode 10.1 to Xcode 11.4. One of the function in the project is to perform RSA encryption/decryption. It works well in Xcode 10.1. However in Xcode 11.4, it starts to return errSecParam randomly. No error when I run the app in debug mode. Also, in release mode, I have tried to turn off all optimizations but the same issue still occurs. The following is the details of the issue.let status = SecKeyDecrypt(privateKey, SecPadding.PKCS1, chunkData, length, &decryptedDataBuffer, &decryptedDataLength)where the legnth of chunkData is 256, legnth = 256, the length of decryptedDataBuffer is 256 with all 0 in the array and decryptedDataLength 256.I would like to ask what will cause SecKeyDecrypt function returns errSecParam? And is there any change for this function in iOS 13 SDK?Thanks for your help!
