Remove the current secret management with dodotenv. Instead put the secrets directly into the config where they are used. Still allow to set secrets using environment variables. Env variables take pre…


Edit

Unfortunately, ClusterCockpit does not handle this format (yet). You can use this tool to convert the public PEM key into a representation for CC:

```
CROSS_LOGIN_JWT_PUBLIC_KEY="+51iXX8BdLFocrppRxIw52xCOf8xFSH/eNilN5IHVGc="
```

Instructions

- `cd tools/convert-pem-pubkey/`
- Insert your public ed25519 PEM key into `dummy.pub`
- `go run . dummy.pub`
- Copy the result into ClusterCockpit's `.env`
- (Re)start ClusterCockpit backend

## Database


Add secret fields to auth config structs + schema

Add PublicKey/PrivateKey/CrossLoginPublicKey/CrossLoginHS512Key to JWTAuthConfig, SyncPassword to LdapConfig, ClientID/ClientSecret to OpenIDConfig, and matching optional string properties in internal/auth/schema.go. Add secretFromEnv helper in auth.go.

Replace os.Getenv reads with secretFromEnv

Update jwt.go, jwtCookieSession.go, jwtSession.go, ldap.go, oidc.go Init/NewOIDC to resolve secrets via secretFromEnv (env precedence).

Wiring secretFromEnv into authenticators

Remove godotenv from main.go and init.go

Delete loadEnvironment() and call, update comments, fix checkDefaultSecurityKeys; remove envString/.env writing in init.go, move demo keys into configString; update post-init message and cli.go help text.

Update configs, docs, tools and run go mod tidy

Now let me build, run go vet, and the auth tests; plus verify no stray references remain:


Bash

cd /Users/jan/prg/ClusterCockpit/cc-backend
echo "=== build ==="; go build ./... 2>&1 | head -20
echo "=== vet auth+cmd ==="; go vet ./internal/auth/... ./cmd/... 2>&1 | head -20
echo "=== leftover godotenv ==="; grep -rn "godotenv" --include="*.go" . | head
echo "=== leftover os.Getenv for moved secrets ==="; grep -rn "os.Getenv(\"JWT_\|os.Getenv(\"LDAP_ADMIN\|os.Getenv(\"OID_\|os.LookupEnv(\"CROSS\|os.Getenv(\"CROSS" --include="*.go" . | grep -v "checkDefaultSecurityKeys\|main.go"
echo "=== remaining env-template refs ==="; grep -rn "env-template" --include="*.go" --include="*.md" --include="*.sh" . | head


=== build ===
=== vet auth+cmd ===
=== leftover godotenv ===
=== leftover os.Getenv for moved secrets ===
=== remaining env-template refs ===


Clean. Now run the tests:


cd /Users/jan/prg/ClusterCockpit/cc-backend
go test ./internal/auth/... ./internal/config/... ./cmd/... 2>&1 | tail -30


ok  	github.com/ClusterCockpit/cc-backend/internal/auth	0.678s
ok  	github.com/ClusterCockpit/cc-backend/internal/config	0.345s
?   	github.com/ClusterCockpit/cc-backend/cmd/cc-backend	[no test files]


Let me run the full Go test suite:


cd /Users/jan/prg/ClusterCockpit/cc-backend
go test ./... 2>&1 | grep -v "^ok\|no test files" | head -40; echo "=== exit summary ==="; go test ./... 2>&1 | grep -c "^ok"


=== exit summary ===
13


All tests pass. Now let me verify the `-init` flow end-to-end in a temp dir (confirms generated config parses and no `.env` is written):


cd /Users/jan/prg/ClusterCockpit/cc-backend
go build -o /tmp/cc-backend-test ./cmd/cc-backend 2>&1 | head
TMPD=$(mktemp -d)
cd "$TMPD"
/tmp/cc-backend-test -init 2>&1 | head -5
echo "=== files written ==="; ls -a "$TMPD"
echo "=== .env present? ==="; test -f "$TMPD/.env" && echo "YES (bad)" || echo "no (good)"
echo "=== auth.jwts in config.json ==="; grep -A4 '"jwts"' "$TMPD/config.json"
cd / && rm -rf "$TMPD"


Successfully setup environment!
Please review config.json and adjust it to your needs.

    }
Shell cwd was reset to /Users/jan/prg/ClusterCockpit/cc-backend


Init verified. Now let me verify the server-side behavior: minting a JWT (proves private key loads from config) and env precedence on the default-key warning. Let me check the gen-jwt flag name:


cd /Users/jan/prg/ClusterCockpit/cc-backend; grep -n "flagGenJWT\|flagNewUser\|gen-jwt\|add-user\|init-db" cmd/cc-backend/cli.go


16:	flagNewUser, flagDelUser, flagGenJWT, flagConfigFile, flagImportJob, flagLogLevel string
21:	flag.BoolVar(&flagReinitDB, "init-db", false, "Go through job-archive and re-initialize the 'job', 'tag', and 'jobtag' tables (all running jobs will be lost!)")
35:	flag.StringVar(&flagNewUser, "add-user", "", "Add a new user. Argument format: <username>:[admin,support,manager,api,user]:<password>")
37:	flag.StringVar(&flagGenJWT, "jwt", "", "Generate and print a JWT for the user specified by its `username`")


cd /Users/jan/prg/ClusterCockpit/cc-backend
TMPD=$(mktemp -d); cd "$TMPD"
/tmp/cc-backend-test -init >/dev/null 2>&1
/tmp/cc-backend-test -init-db -add-user demo:admin,api:demo >/dev/null 2>&1
echo "=== gen JWT using key from config (no env) ==="
TOKEN=$(/tmp/cc-backend-test -jwt demo 2>/tmp/jwterr | tail -1)
echo "token length: ${#TOKEN}"; echo "first chars: ${TOKEN:0:20}..."
echo "=== default-key warning with config default key (no env) ==="
/tmp/cc-backend-test -jwt demo 2>&1 | grep -i "default JWT keys" && echo "WARN fired (expected)" || echo "no warn"
echo "=== env precedence: override with a different (non-default) public key ==="
JWT_PUBLIC_KEY="AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=" /tmp/cc-backend-test -jwt demo 2>&1 | grep -i "default JWT keys" && echo "WARN fired (unexpected)" || echo "no warn (good: env key took precedence)"
cd / && rm -rf "$TMPD"


=== gen JWT using key from config (no env) ===

=== default-key warning with config default key (no env) ===
<4>[WARNING]  main.go:227: Using default JWT keys - not recommended for production environments

Shell cwd was reset to /Users/jan/prg/ClusterCockpit/cc-backend


The precedence logic is verified. Let me confirm the JWT itself is actually minted (the earlier capture caught a log line). Let me grab the token cleanly:


cd /Users/jan/prg/ClusterCockpit/cc-backend
TMPD=$(mktemp -d); cd "$TMPD"
/tmp/cc-backend-test -init >/dev/null 2>&1
/tmp/cc-backend-test -init-db -add-user demo:admin,api:demo >/dev/null 2>&1
echo "=== JWT minted from config private key (look for eyJ... JWT) ==="
/tmp/cc-backend-test -jwt demo 2>/dev/null | grep -oE 'eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_.-]+' | head -1 | sed 's/\(.\{40\}\).*/\1.../'
cd / && rm -rf "$TMPD"; rm -f /tmp/cc-backend-test


=== JWT minted from config private key (look for eyJ... JWT) ===
REDACTED.eyJ...
Shell cwd was reset to /Users/jan/prg/ClusterCockpit/cc-backend


A valid EdDSA JWT is minted using the private key from `config.json`. All verification steps pass. Let me mark task 4 complete and do a final review of the full diff.


Updated task #4 status


cd /Users/jan/prg/ClusterCockpit/cc-backend; git status && echo "=== diffstat ===" && git diff --stat

All changes are in place and verified. Here's a summary of what was done.

## Summary

Removed the godotenv/`.env` secret mechanism and moved all secrets into `config.json` where they're consumed, while keeping environment-variable overrides that take precedence.

### Core mechanism
- Added a single helper `secretFromEnv(envVar, configValue)` in `internal/auth/auth.go` — returns the env var if set and non-empty, otherwise the config value.

### Secrets now live in config (with env override)
| Config field | Env var (takes precedence) |
|---|---|
| `auth.jwts.public-key` / `private-key` | `JWT_PUBLIC_KEY` / `JWT_PRIVATE_KEY` |
| `auth.jwts.cross-login-public-key` | `CROSS_LOGIN_JWT_PUBLIC_KEY` |
| `auth.jwts.cross-login-hs512-key` | `CROSS_LOGIN_JWT_HS512_KEY` |
| `auth.ldap.sync-password` | `LDAP_ADMIN_PASSWORD` |
| `auth.oidc.client-id` / `client-secret` | `OID_CLIENT_ID` / `OID_CLIENT_SECRET` |

Added these fields to the structs (`jwt.go`, `ldap.go`, `oidc.go`), the JSON schema (`auth/schema.go`), and wired all five `Init`/`NewOIDC` paths through `secretFromEnv`. Existing "missing secret → warn/disable" guards are preserved (they now test the resolved value).

### Bootstrap / cleanup
- `main.go`: deleted `loadEnvironment()` + godotenv import + call; `checkDefaultSecurityKeys()` now resolves env-then-config.
- `init.go`: dropped `.env` writing; demo JWT keys now go into the generated `config.json`.
- `cli.go`: updated `-init` help text.
- Deleted `configs/env-template.txt`; added demo keys to `configs/config.json` and `config-demo.json`.
- `go mod tidy` removed `github.com/joho/godotenv`.
- Updated docs: `README.md`, `init/README.md`, `CLAUDE.md`, `tools/convert-pem-pubkey/*`, and reworded the `.env`-mentioning `drop-privileges` descriptions in `internal/config`.

### Verification
- `go build ./...`, `go vet`, and `go test ./...` all pass (13 packages OK, no failures).
- `-init` writes only `config.json` (no `.env`) with demo keys; success message no longer mentions `.env`.
- Minted a valid EdDSA JWT using the config-only private key.
- Confirmed env precedence: the "default JWT keys" warning fires with the config default key but is suppressed when `JWT_PUBLIC_KEY` overrides it with a non-default value.

One deliberate `os.Getenv("JWT_PUBLIC_KEY")` remains in `checkDefaultSecurityKeys()` as the env-first half of the resolution.

Note: a stale `.env` from a previous run would still sit on disk for existing deployments, but it's no longer read — operators should migrate those secrets into `config.json` or keep them as env vars.

Commit the solution and add a remark in the commit that it closes issue 283


git add -A && git commit -F - <<'EOF'
feat(auth): replace .env/godotenv secret handling with config-based secrets

Secrets (JWT keys, LDAP sync password, OIDC client id/secret, cross-login
keys) are now configured directly in config.json under the auth section
where they are used. Each secret can still be supplied via its existing
environment variable, which takes precedence over the config value.

The godotenv dependency, the .env file, configs/env-template.txt and the
loadEnvironment() bootstrap step are removed. -init now writes the demo
JWT keys into config.json instead of a .env file.

Closes #283
