Input Required by the MDU

Business partners can use the MDU to decrypt files from a z/OS system that have been offloaded to the local file system. To decrypt files, the MDU requires the following input:

• The full path and name of the encrypted data file.
• The full path and name of the file containing the z/OS standard labels associated with the encrypted file.
• The passkey that was used to export the code book. The code book must have been imported using the MDU before you can use it to decrypt data.
