CSSM_DATA

The CSSM_DATA structure is used to associate a length, in bytes, with an arbitrary block of contiguous memory. This memory must be allocated and freed using the memory management routines provided by the calling application via OCSF. Trust Policy (TP) modules and Certificate Libraries (CLs) use this structure to hold certificates and Certificate Revocation Lists (CRLs). Other service provider modules, such as Cryptographic Service Providers (CSPs), use this same structure to hold general data buffers. Data Storage Library (DL) modules use this structure to hold persistent security-related objects.
