## [2026-08-09] - ADL-002: chronogrid_crypto Crate – Argon2id KDF & OS Keychain
|
||||||
|
|
||||||
|
- **Status**: Accepted
|
||||||
|
- **Context**: Task 1.2 required implementing the `chronogrid_crypto` crate with Argon2id master-key derivation and OS-native keychain bindings per `docs/ARCHITECTURE/02-security-and-crypto.md`.
|
||||||
|
- **Decision**:
|
||||||
|
- Argon2id parameters pinned: 64 MiB memory, 3 iterations, 4 threads, 16-byte random salt, 32-byte output.
|
||||||
|
- `DerivedKey` struct implements `Zeroize + Drop` to scrub sensitive memory on scope exit.
|
||||||
|
- OS keychain abstracted via `keyring` crate v3 (Windows Credential Manager / DPAPI, Linux SecretService / libsecret). Android keychain is excluded (`cfg(not(target_os = "android"))`) and will be handled by Flutter KeyStore bridge in Task 1.5.
|
||||||
|
- Raw key material is Base64-encoded before credential-store insertion for UTF-8 backend compatibility.
|
||||||
|
- Inline Base64 encode/decode helpers avoid adding an external Base64 dependency.

|
//! 1. **Argon2id master-key derivation** ([`kdf`]) — derives a 256-bit key from a

|
//! `docs/ARCHITECTURE/02-security-and-crypto.md`.

# ADR-0002: chronogrid_crypto – Argon2id KDF & OS Keychain Strategy

## Context & Problem Statement
|
||||||
|
|
||||||
|
Task 1.2 requires implementing a `chronogrid_crypto` crate that provides:
|
||||||
|
1. A master-key derivation function using Argon2id with parameters mandated by `docs/ARCHITECTURE/02-security-and-crypto.md`.
|
||||||
|
2. Cross-platform OS keychain bindings for secure credential persistence (Windows, Linux). Android is deferred to the Flutter KeyStore bridge.
|
||||||
|
|
||||||
|
## Options Considered
|
||||||
|
|
||||||
|
1. **Hand-roll Argon2id via raw `blake2` + memory-hard loop** — maximum control but high risk of implementation bugs in a security-critical path.
|
||||||
|
2. **Use the `argon2` crate (RustCrypto)** — well-audited, widely used, supports Argon2id with configurable parameters out of the box.
|
||||||
|
3. **Use `ring` or `sodiumoxide`** — neither provides Argon2id natively; would still need the `argon2` crate.
|
||||||
|
|
||||||
|
For keychain:
|
||||||
|
1. **Direct Win32 / libsecret FFI** — full control, but significant per-platform maintenance burden.
|
||||||
|
2. **`keyring` crate** — abstracts Windows Credential Manager, Linux SecretService, and macOS Keychain behind a single API.
|
||||||
|
|
||||||
|
## Decision Outcome
|
||||||
|
|
||||||
|
**Chosen Options:**
|
||||||
|
- `argon2` crate v0.5 (RustCrypto) for KDF — spec-compliant, zero-copy output, and widely audited.
|
||||||
|
- `keyring` crate v3 for cross-platform OS keychain — minimal code, covers Windows + Linux targets. Android is excluded via `cfg(not(target_os = "android"))` and will be handled by the Flutter KeyStore bridge.
|
||||||
|
|
||||||
|
**Key design choices:**
|
||||||
|
- Argon2id parameters: memory = 65 536 KiB (64 MiB), time_cost = 3, parallelism = 4, salt = 16 bytes, output = 32 bytes.
|
||||||
|
- `DerivedKey` struct wraps key + salt and implements `Zeroize + Drop` for automatic memory scrubbing.
|
||||||
|
- `Debug` impl on `DerivedKey` redacts key material to prevent accidental log leaks.
|
||||||
|
- Raw bytes are Base64-encoded before keychain insertion for UTF-8 credential backend compatibility, using inline encode/decode helpers (no extra dependency).
|
||||||
|
|
||||||
|
## Consequences & Trade-offs
|
||||||
|
|
||||||
|
* **Positive**: Spec-compliant crypto with secure memory handling; single cross-platform keychain API; 8 unit tests + 1 doc-test provide baseline confidence.
|
||||||
|
* **Negative**: `keyring` v3 does not support Android — Android keychain must be wired separately via Flutter platform channels (planned for Task 1.5). Inline Base64 is minimal but could be replaced by `base64` crate if other crates need it later.
