How Business Partners Read Files Encrypted by Code Books

Business partners in non-z/OS environments can read files encrypted in z/OS environments as outlined by the following points:

• The business partner must have the freely distributed version of the CA Tape Encryption Multiplatform Decryption Utility (MDU) to read the encrypted tape.
• The business partner uses the MDU to import the version of the code book that was exported from the z/OS environment by the originator of the tape. You only need to import each version of a code book one time.
• The business partner uses existing tools or utilities in the non-z/OS environment to do the following:
  • Offload encrypted tape files from the z/OS standard tapes to the local file system.
  • Unload the z/OS standard tape labels into a local file.
  • The business partner then uses the MDU to decrypt the encrypted local file.
