SPX

A file archive library for bundling and protecting resources using compile-time code generation.

A generated SPX archive file does not contains any metadata. Each files are encrypted with Chacha20 using sha256 hash of file path as key. Offset and size for each files are mapped with perfect hash table and stored inside compiled binary without original filename. But without correct file name, it is impossible to find correct offset size pair and original file data.
