Techniques for modifying specific byte offsets within a binary signature block to inject data without altering the cryptographic signature.
Distinct from Binary Signing: Distinct from Binary Signing: focuses on post-signing modification of the signature block rather than the initial signing process.

Walle is a tooling system for automating the injection of distribution channel identifiers and metadata into signed Android application binaries. It functions as a command-line utility and build pipeline extension that reads and writes custom metadata directly into the Android application signing block. The tool specifically modifies the Android Signature V2 block to embed channel identifiers and key-value pairs without re-signing the binary. This approach enables the generation of multiple channel-specific application packages without requiring a full binary rebuild or repeated signing opera
Provides low-level binary patching of APK signing blocks to embed metadata while preserving cryptographic validity.
