Add a pytest suite covering the pure logic of the DeDRM and Obok plugins.
Because the plugins normally run inside calibre and use intra-package
imports, tests/dedrm_test_utils.py sets up an import shim (plugin dirs on
sys.path, a minimal calibre stub, and a synthetic `dedrm` package) so the
modules can be imported and exercised standalone.
Coverage:
- alfcrypto: PC1 and Topaz cipher round-trips, PBKDF2 vs hashlib.
- kgenpids / kindlepid: PID encoding, bit-field extraction, device-PID
and serial-PID known vectors, CRC32.
- mobidedrm: PC1 round-trip, trailing-data sizing, bad-key handling.
- ineptpdf / ineptepub: nunpack and PKCS7 unpad.
- topazextract: encoded number/string parsing, plus a regression test
that a malicious header tag ("../../evil") cannot escape the output
directory (covers the path-traversal fix).
- obok: unpad, hash-key table, SafeUnbuffered str/bytes handling.
- utilities / argv_utils: uStrCmp normalisation, unicode_argv.
- erdr2pml: deXOR/sanitiseFileName, skipped on Python 3.13+ where the
module's `cgi` import is unavailable.
Run with `poetry install` then `poetry run pytest`. 36 pass, 2 skip on
Python 3.13+.
Note: this surfaced two dead-code modules that are broken on Python 3
(aescbc's pure-Python AES and kgenpids.decode, neither on a live path,
since the real crypto goes through pycryptodome); left as-is here.
