ICSF has implemented additional metadata for key data sets records. The metadata include key material validity dates, last referenced, archive and recall dates, and IBM and installation metadata blocks. This metadata can be used as search criteria for the Key Data Set List callable service. The metadata can be read using the Key Data Set Metadata Read service. Some of the metadata can be added, deleted, and changed using the Key Data Set Metadata Write service. For additional details, see z/OS Cryptographic Services ICSF Administrator's Guide.
In order to exploit this functionality, the key data sets must be in the KDSR format, introduced in HCR77A1. Existing data sets can be converted to the KDSR format using the Coordinated KDS Administration callable service. For additional details, see z/OS Cryptographic Services ICSF Application Programmer's Guide.
