1. Wild Card Characters
Locate Operation
Nitin Jain ( Safenet )

2. Introduction
Issue :
KMIP spec is ambiguous about the wildcard characters usage with Locate operation
“Wild-cards or regular expressions (defined, e.g., in [ISO/IEC ]) MAY be supported by specific key management system implementations for matching attribute fields when the field type is a Text String or a Byte String”
Solution :
- Introduce a new Tag regarding pattern matching with Wild Card Chars.
- KMIP should provide support for “*” and “?” for the time being to understand the vendors experience.

3. Sample <BatchItem>
Suppose if Keys named Key1, Key2 and Key3 are stored in DB, then above Locate request will return all keys starting with “Key” pattern i.e. Key1, Key2 & Key3
<BatchItem>
    <Operation type="Enumeration" value="Locate"/>
    <RequestPayload>
      <Attribute>
        <AttributeName type="TextString" value="Object Type"/>
        <AttributeValue type="Enumeration" value="SymmetricKey"/>
      </Attribute>
        <AttributeName type="TextString" value="Name"/>
        <AttributeValue>
<NameValue >
      <Pattern type="TextString" value="Key*"/>
    </NameValue>
          <NameType type="Enumeration"  value="UninterpretedTextString"/>
        </AttributeValue>
    </RequestPayload>
</BatchItem>
