The "AAD.Core.dll" file is a Dynamic Link Library (DLL) provided by Microsoft Corporation and is part of the Windows operating system. "AAD" stands for Azure Active Directory, which is Microsoft's cloud-based identity and access management service. The file is primarily used for token brokering, a process where the DLL assists in managing security tokens required for authentication.
In simpler terms, this DLL acts as a core component that helps in the secure identification and verification of users who are trying to access services, usually in a corporate environment that uses Microsoft's Azure services. The token broker service facilitated by this DLL ensures that authentication tokens are properly issued, renewed, and managed, making sure that only authorized users gain access to specific resources.
Given that this is a system-related DLL, it usually runs in the background and you typically won't have to interact with it directly. It's an essential part of ensuring secure communications and operations in an Azure Active Directory environment.
In summary, "AAD.Core.dll" is a specialized DLL file that plays a key role in the management of security tokens within the Azure Active Directory services. It's a legitimate, important component for systems that are integrated with Azure services.
