Seamless data access for your Scala application — Write Scala code to query your database.
All database entities and queries are statically checked at compile-time.
Compose query operations just as if you were using Scala's collections.
Navigate through the folders: Computer Configuration -> Administrative Templates -> Windows Components -> Smart Card .
This hash is likely generated from a specific URL, email attachment hash, or rule set. When a request triggers a rule, the filter logs this CID to identify which policy was applied (e.g., block, allow, quarantine).
The scfilter component is a kernel-mode driver in Windows that acts as an intermediary between a smart card reader and the operating system. Its primary roles include: scfilter cid87d25e32ac0d4ef0b1e0502c6b7dfb77
Restart your computer to allow the subsystem to hook back into the PnP manager. 2. Install the Official Vendor Middleware or Minidriver
It looks like you’re referencing a specific filter identifier — possibly from a network security tool, firewall rule, or content filter system. The scfilter component is a kernel-mode driver in
The string scfilter cid87d25e32ac0d4ef0b1e0502c6b7dfb77 is a specific Windows identifier that connects a smart card—the —to its driver via the system's SCFILTER mechanism. Understanding this Hardware ID helps demystify how Windows manages smart card hardware, provides a foundation for troubleshooting, and ensures the integrity of your system's driver files.
The identifier SCFILTER\CID_87d25e32ac0d4ef0b1e0502c6b7dfb77 typically refers to a Generic Smart Card Install the Official Vendor Middleware or Minidriver It

Data within the ATR that provides information about the card's manufacturer and capabilities.
The scfilter prefix suggests a or stream classifier filter . Many web proxies, email gateways, and CDNs (like Cloudflare, Barracuda, or Proofpoint) use such filters to inspect traffic. The cid part likely stands for classification ID or content ID .
Whenever a physical smart card (such as an enterprise identity badge, yubikey, or government CAC) is slotted into a hardware terminal, Windows queries the device ID through the Microsoft Learn Smart Card Discovery Process to map out how software will communicate with the secure element.
