# devirt-corpus

Obfuscated JavaScript with per-sample deobfuscation metrics. Each sample is run
through a deobfuscator; the obfuscated input, the deobfuscated output, and
readability scores are published in `metrics/*.jsonl` and browsable in the
Dataset Viewer.

## Columns

| column | meaning |
|---|---|
| `path` | sample path |
| `source` | technique / origin (e.g. `generated/strings_rc4`, `real/tranco`) |
| `in_bytes` / `out_bytes` | obfuscated input vs. deobfuscated output size |
| `kept_pct` | `out_bytes / in_bytes` |
| `opaque_in` / `opaque_out` | percent of identifiers that look machine-generated (hex `_0x…` or 1–2 chars), before and after |
| `input` / `output` | the obfuscated and deobfuscated source |

## Layout

- `generated/<profile>/<seed>.js` — seeds obfuscated under
  [javascript-obfuscator](https://github.com/javascript-obfuscator/javascript-obfuscator)
  profiles.
- `real/<source>/…` — real-world scripts, filtered and deduped.
- `seeds/` — the plain source programs the generated set is built from.
- `metrics/*.jsonl` — the per-sample table that powers the Dataset Viewer.
