Internet delivery uses a combination of industry standard authentication and data integrity approaches to provide security for information about your order and to ensure the integrity of the contents of your order. Your Shopz user ID and password protects sensitive data associated with your order from access by others. This sensitive data includes the status of your order and information required to access your order on the IBM® server.

Hashing algorithms are used for both download methods (directly to z/OS® and to a workstation as an intermediate node). For downloads directly to z/OS, SMP/E ensures the data integrity of your package through its assignment of a hash value during packaging of your order and verification of that hash value upon download. SMP/E uses the ICSF One-Way Hash Generate callable service, or the Java™ application class if ICSF is not configured, to perform the verification.

When you use Secure FTP (FTPS) or HTTP Secure (HTTPS) to download your order directly to your z/OS host system, the package is encrypted during transmission. When you use Download Director to download your order to a workstation as an intermediate node, the package is encrypted during transmission.
