TOKENINFORMATIONCLASS

TOKENINFORMATIONCLASS is an enumeration that defines the types of information that can be queried from an access token in Microsoft Windows operating systems. This enumeration is used in conjunction with Windows API functions such as GetTokenInformation to retrieve specific details about a security token. Access tokens are fundamental objects in Windows security, representing a user's security context. By specifying a TOKENINFORMATIONCLASS value, a caller can request information such as the token's owner, its group memberships, privileges, logon session ID, or whether it is a primary or impersonation token. Other values allow for the retrieval of token elevation status, restricted SIDs, and token source information. Understanding these classes is crucial for developers working with Windows security features, auditing, and process management, as it provides a programmatic way to inspect and understand the security attributes of a running process or user session. Each member of the TOKENINFORMATIONCLASS enumeration corresponds to a specific data structure that will be populated by the GetTokenInformation function if the request is successful.
