From 8e1e8133b473d98ae6c8990864d931b09d865ef3 Mon Sep 17 00:00:00 2001 From: Yousef Hussein Date: Tue, 23 Jun 2026 15:53:05 +0300 Subject: [PATCH 01/11] refactor(auth): Rework password hashing foundation Add BcryptSha256, Scrypt, Pbkdf2Sha512 enum variants. Wire get_or_init_dummy_hash with double-checked locking. Replace Passlib-specific base64 with standard STANDARD/STANDARD_NO_PAD engines. PBKDF2 now emits bare-integer format and reads configured rounds. Replace magic numbers with named bcrypt constants.

ScryptHasher now uses ln=16,r=8,p=1 and STANDARD_NO_PAD to match Python Keystone's wire format exactly. PBKDF2 is implemented directly with workspace hmac/sha2 to avoid a digest v0.10/v0.11 type conflict with pbkdf2 v0.12. Cache reset hook added for config-reload wiring. KAT generator gains correct pre-dispatch truncation policy. Adds tools/cross_verify.py for bidirectional Python compatibility testing.

TEST_PASSWORD and mock_config are now #[cfg(test)] items directly in mod.rs; child modules access them via the private ancestor path (super::super::mock_config) without needing pub(crate). Also set up Python Keystone in CI so the cross-verify tests run for real instead of being silently skipped: clone openstack/keystone, install bcrypt + cryptography, and set KEYSTONE_PYTHON_CHECKOUT for the unit test step.
