sRDI is a compact project that implements a shellcode form of Reflective DLL Injection, enabling DLLs to be converted into position-independent shellcode and loaded in memory by a small in-process PE loader. The codebase groups a C implementation of a reflective PE loader with multiple loader/wrapper components (native C loader, a .NET loader, Python and PowerShell conversion helpers) so authors can produce and embed sRDI blobs in different environments.

...The tool offers options for compression and encryption so the embedded content is both smaller and protected by a passphrase when required. It includes helpers to encode a payload into an image, decode an embedded payload back to readable form, and run the extracted content directly from memory to avoid touching disk. Designed as a compact, single-file PowerShell script, it relies on .NET imaging APIs to manipulate pixel data or metadata and to store the payload in a way that survives ordinary file transfers.
