- Existing `go-backend/` is set aside; new code lives in a fresh `backend/` Go package.

- DB schema is changing from the JS/Supabase version — user is in the loop on every schema decision (Phases 2–5).

# Phase 2 Plan 02: argon2id Hash + Verify (TDD) Summary
|
||||
|
||||
**One-liner:** argon2id PHC-encoded password Hash + constant-time Verify with OWASP 2024 DefaultParams, reduced-cost TestParams, and init() self-test — TDD with RED commit 3bb3828 then GREEN commit ee36a5c.
|
||||
|
||||
## What Was Built
|
||||
|
||||
### Task 1 (RED): Failing tests — `backend/internal/auth/password_test.go`
|
||||
|
||||
Six test functions written against the (not yet existing) `auth.Hash` and `auth.Verify` API:
|
||||
|
||||
| Test | Guards |
|
||||
|------|--------|
|
||||
| `TestPassword_HashVerify` | Round-trip: Hash returns valid PHC prefix `$argon2id$v=19$m=8192,t=1,p=2$`; Verify returns (true, nil) |
|
||||
| `TestPassword_VerifyWrong` | Wrong password returns (false, nil) — not an error |
|
||||
| `TestPassword_VerifyMalformed` | 3 sub-cases (plain string, too few segments, wrong algorithm) each return (false, ErrInvalidHash) |
|
||||
| `TestPassword_VerifyVersion` | Synthetic PHC with v=18 returns (false, ErrIncompatibleVersion) |
|
||||
| `TestPassword_DistinctSaltsPerCall` | Two Hash calls for same password produce different PHC strings (random salt) |
|
||||
| `TestPassword_DefaultParamsShape` | DefaultParams exactly matches OWASP 2024 baseline (m=64KiB, t=1, p=4, salt=16, key=32) |
|
||||
|
||||
All tests used `auth.TestParams` for fast wall time. Compile failure confirmed RED state (undefined: auth.Hash / auth.TestParams / auth.Verify).
|
||||
|
||||
### Task 2 (GREEN): Implementation — `backend/internal/auth/password.go`
|
||||
|
||||
Implemented per RESEARCH Pattern 1 verbatim:
|
||||
|
||||
- **`Params` struct**: `Memory uint32`, `Iterations uint32`, `Parallelism uint8`, `SaltLength uint32`, `KeyLength uint32`
|
||||
- **`DefaultParams`**: `m=64*1024, t=1, p=4, SaltLength=16, KeyLength=32` — OWASP 2024 baseline (D-08)
|
||||
- **`TestParams`**: `m=8*1024, t=1, p=2, SaltLength=16, KeyLength=32` — reduced cost for test speed
|
||||
- **`Hash(password string, p Params) (string, error)`**: `crypto/rand` salt per call, `argon2.IDKey`, PHC format `$argon2id$v=%d$m=%d,t=%d,p=%d$<b64salt>$<b64hash>` via `base64.RawStdEncoding`
|
||||
- **`Verify(encoded, password string) (bool, error)`**: `strings.Split` on `$` into 6 parts, checks `parts[1] == "argon2id"`, parses `v=%d`, rejects `v != argon2.Version` with `ErrIncompatibleVersion`, parses params, decodes salt+hash with `base64.RawStdEncoding.Strict()`, recomputes via `argon2.IDKey`, compares with `subtle.ConstantTimeCompare`
|
||||
- **`init()` self-test**: Hash + Verify round-trip using TestParams; panics on any failure (T-2-15)
|
||||
|
||||
Added `golang.org/x/crypto v0.51.0` as a direct dependency via `go get` + `go mod tidy`.
|
||||
|
||||
## TDD Gate Compliance
|
||||
|
||||
| Gate | Commit | Status |
|
||||
|------|--------|--------|
|
||||
| RED (test commit) | 3bb3828 — `test(02): RED — failing argon2id password tests` | PASS |
|
||||
| GREEN (feat commit) | ee36a5c — `feat(02): GREEN — argon2id Hash + Verify + self-test` | PASS |
|
||||
| REFACTOR | Not required — implementation is clean from the start | N/A |
|
||||
|
||||
Verified via `git log --oneline`: RED commit precedes GREEN commit.
|
||||
|
||||
## argon2 Library Version
|
||||
|
||||
`golang.org/x/crypto v0.51.0` — verified as latest on 2026-05-14 per RESEARCH Standard Stack. This version provides `golang.org/x/crypto/argon2` with `argon2.IDKey` and `argon2.Version == 19`.
|
||||
|
||||
## DefaultParams Confirmed (D-08)
|
||||
|
||||
| Param | Value | OWASP 2024 Baseline |
|
||||
|-------|-------|---------------------|
|
||||
| Memory | 65536 KiB (64 MiB) | 64 MiB |
|
||||
| Iterations | 1 | 1 |
|
||||
| Parallelism | 4 | 4 |
|
||||
| SaltLength | 16 bytes | 16 bytes |
|
||||
| KeyLength | 32 bytes | 32 bytes |
|
||||
|
||||
`TestPassword_DefaultParamsShape` enforces this shape at compile time against accidental drift.
|
||||
|
||||
## Observed Wall Time
|
||||
|
||||
```
|
||||
ok backend/internal/auth 0.27s
|
||||
```
|
||||
|
||||
Well under the 5-second limit (D-26, Pitfall 4). The init() self-test adds ~10ms using TestParams.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None — Pattern 1 from RESEARCH implemented verbatim. No wrapper library introduced. PHC format, constant-time compare, salt randomness, and init() self-test all match the plan specification exactly.
|
||||
|
||||
## Threat Surface Scan
|
||||
|
||||
No new network endpoints, auth paths, file access patterns, or schema changes introduced. This plan is pure in-process CPU computation with no external surface.
|
||||
|
||||
T-2-01 mitigated: argon2id PHC with per-call random salt; TestPassword_HashVerify + TestPassword_DistinctSaltsPerCall verify.
|
||||
T-2-13 mitigated: `subtle.ConstantTimeCompare` final compare verified by acceptance grep.
|
||||
T-2-14 (DoS/long password): contract documented on Hash() — length ceiling enforced by handler (Plans 04/05).
|
||||
T-2-15 mitigated: `init()` self-test panics on param drift; `TestPassword_DefaultParamsShape` locks DefaultParams shape.
