# Benchmark

A benchmark for evaluating AI/LLM agents at reverse-engineering encryption
protocols used by Android mobile applications. Each task provides a decompiled
Android app and captured network traffic; the goal is to identify the cipher,
extract the key material, and produce a working encryption implementation that
can decrypt the captured ciphertexts.

## File formats

### `input/ciphertexts.json`

Array of ciphertext samples captured from network traffic.

```json
[
  {
    "file": "input/traces/com.example.app.pcapng",
    "packet_number": 463,
    "ciphertext": "b31e48f9a23dcf1d...",
    "encoding": "hex"
  }
]
```

| Field           | Description                                      |
|-----------------|--------------------------------------------------|
| `file`          | Relative path to the source pcapng trace file    |
| `packet_number` | Packet index within the trace file               |
| `ciphertext`    | Hex-encoded ciphertext bytes                     |
| `encoding`      | Always `"hex"`                                   |

### `expected_output/audit.json`

Structured description of the encryption protocol. Validated against
`common/audit_schema.json`.

```json
{
  "ciphers": [
    {
      "cipher": "DES",
      "mode": "ECB",
      "padding": "pkcs7"
    }
  ],
  "vulnerable": true,
  "key_exchange": "none",
  "key_hex": "577331566378376e",
  "iv_hex": null
}
```

### `expected_output/encrypt.py`

Executable Python script implementing the cipher. Follows the interface defined
in `common/encrypt_template.py`:

```
python encrypt.py <plaintext_hex> [--key-hex KEY] [--iv-hex IV]
```

Reads plaintext as hex on the command line, prints ciphertext as hex to stdout.
Applies only the cipher layer -- no compression, base64, or transport encoding.

Expects Python >= 3.11. Install from `common/pyproject.toml`:

```sh
cd common && pip install .
```

### `expected_output/plaintexts.json`

Same structure as `ciphertexts.json` with an added `decrypted` field containing
the known plaintext as a hex string:

```json
[
  {
    "file": "input/traces/com.example.app.pcapng",
    "packet_number": 463,
    "ciphertext": "b31e48f9a23dcf1d...",
    "encoding": "hex",
    "decrypted": "7b22617070766572..."
  }
]
```
