OIC - Error occurred while processing activity decryptsf4. Error: java.io.IOException: Error in decrypting the stream for file f:

Usecase: We have received an encrypted file from source and while trying to decrypt it using stage action, throwing below error:

The error message reads:

"Error occurred while processing activity decryptsf4. Error: java.io.IOException: Error in decrypting the stream for file f: /ocid1_integrationinstance_oc1_ap_singapore_1_amaaaaaalbz6auaavjgs3l7ic3amccbdcvgvjg3zohgwapphstnp4u2rpukq/PzDTInsnEe_TfH17CejA/in/t332/download/SourceName_HCM_PayrollResults_20240827_123456.csv"

Root cause: 

The root cause of the error seems to be a mismatch between the key pairs used for encryption and decryption. 

Specifically, the key pair used to encrypt the file and the key pair present in the Oracle Integration Cloud (OIC) certificate store for decryption are different. This mismatch is preventing the successful decryption of the file, leading to the IOException error. 

Solution:

To resolve this issue, ensure that the same key pair is used for both encrypting and decrypting the file.
