About This Tool

The tool performs static analysis on a Windows DLL binary by parsing the PE/COFF headers to extract machine type, version resources, and metadata. It enumerates imports and exports and creates a dependency graph. The results are suitable for developers, QA, and security teams during build, packaging, and incident response.
Conceptually, the tool treats the DLL as a binary data object and derives structural attributes without executing code. It computes a SHA-256 hash for integrity, detects architecture (x86/x64/ARM64), and lists dependent DLLs with their source paths. Optional deep analysis checks digital signatures and compatibility hints.
Unique value lies in deterministic static analysis coupled with clear, actionable outputs: a structured data payload and a human-friendly report that highlight missing dependencies, signature status, and potential conflicts. Use cases include pre-distribution validation, build pipelines, and security audits.

Frequently Asked Questions

Find Quick Answers

What does the tool analyze in a DLL?

It reads the PE header, architecture type, version resources, imports and exports, and the dependency graph to identify missing dependencies and potential conflicts without executing code.

What inputs are required?

At minimum, a DLL binary file is uploaded. Optional batch mode enables analysis of multiple DLLs in one run.

What outputs are provided?

A structured summary including architecture, version info, imports/exports, dependencies, missing items, signature status, file hash, and a human-readable report.

Is the analysis dynamic?

No. The tool performs static analysis of the binary and does not execute the code inside the DLL.

How is privacy handled?

Uploaded binaries are processed to produce results according to the platform’s data handling policy; sensitive data handling follows standard privacy practices.
