Detailed Description

CK_ATTRIBUTE; CK_ATTRIBUTE_PTR

CK_ATTRIBUTE is a structure that includes the type, value, and length of an attribute.
type the attribute type
pValue pointer to the value of the attribute
ulValueLen length in bytes of the value

If an attribute has no value, then ulValueLen = 0, and the value of pValue is irrelevant. An array of CK_ATTRIBUTEs is called a "template" and is used for creating, manipulating and searching for objects. The order of the attributes in a template never matters, even if the template contains vendor-specific attributes. Note that pValue is a "void" pointer, facilitating the passing of arbitrary values. Both the application and Cryptoki library must ensure that the pointer can be safely cast to the expected type (i.e., without word-alignment errors).

CK_ATTRIBUTE_PTR is a pointer to a CK_ATTRIBUTE.

CK_DATE

CK_DATE is a structure that defines a date. It is defined as follows:
