Charles Bochet	75b9b2fe5d	feat(admin-panel): signing keys management tab with usage tracking (#20586 ) ## Summary - Adds a new admin-only Security tab to the Admin Panel (alongside General/Apps/AI/Config/Health) containing a Signing Keys section. The tab is intentionally introduced now so the upcoming Encryption rotation work can land as a sibling section. - Lists every JWT signing key with key id, `createdAt`, `revokedAt`, current/active/revoked status, and a 7-day verification count read from Redis. A trailing row aggregates legacy HS256 verifications so it is clear when the deprecated path is still in use. - Lets an admin revoke a public key. Revoking the current key drops `isCurrent`, sets `revokedAt`, nulls the encrypted `privateKey` and clears the in-process cached current key; the existing lazy path in `JwtKeyManagerService.getCurrentSigningKey()` then mints a fresh current key on the next sign. ## Backend - `SigningKeyVerifyCounterService` — bucketed Redis counter under the existing `EngineMetrics` namespace. 1-day UTC-aligned buckets, 8-day TTL refreshed on every increment, batched read via `mget`. Failures are swallowed and logged at `warn` so a Redis hiccup cannot break auth. - `JwtWrapperService.verifyJwtToken` records verifies after success for both ES256 (`kid` as identifier) and HS256 (the literal `legacy` identifier). - `JwtKeyManagerService.listSigningKeys()` and `revokeSigningKey(id)`: list ordered by `isCurrent DESC, createdAt DESC`; revoke is idempotent, validates the UUID, invalidates the public-key cache, and resets the cached current-key promise. - `AdminPanelResolver.getSigningKeys` (query) and `revokeSigningKey` (mutation) are both decorated with `@UseGuards(AdminPanelGuard)` so they are admin-only, like the 35 existing admin-only methods on this resolver. `privateKey` is never returned over GraphQL. ## Frontend - New `SECURITY` tab id wired into `SettingsAdminContent` and `SettingsAdminTabContent` (gated by `canAccessFullAdminPanel`). - `SettingsAdminSecurity` / `SettingsAdminSigningKeysTable` strictly reuse existing admin-panel components: `Section`, `H2Title`, `Table`/`TableRow`/`TableCell`/`TableHeader` from `@/ui/layout/table`, `Tag`/`Button` from `twenty-ui`, and `ConfirmationModal` mirroring the queue retry/delete modals. Only one minimal styled helper for the monospaced UUID rendering. - `useRevokeSigningKey` uses `useApolloAdminClient`, refetches `GetSigningKeys`, shows success/error snackbars (same pattern as `useRetryJobs`/`useDeleteJobs`). <img width="1293" height="881" alt="image" src="https://github.com/user-attachments/assets/7cf98664-950b-4451-af85-27781a8e9a9c" />	2026-05-15 10:49:18 +00:00
Charles Bochet	ac653182b2	feat(server): migrate all remaining JWT token types to ES256 (#20513 ) ## Summary Extends the asymmetric signing work from #20467 to cover every remaining `JwtTokenTypeEnum` value: `LOGIN`, `WORKSPACE_AGNOSTIC`, `FILE`, `API_KEY`, `APPLICATION_ACCESS`, `APPLICATION_REFRESH`, `APP_OAUTH_STATE`, plus the ACCESS-shaped session token issued by the code interpreter tool. After this PR, every JWT the server signs is ES256 with a `kid` pointing at the current `core."signingKey"` row, while legacy HS256 tokens (no `kid` header) remain verifiable indefinitely through the existing fallback in `JwtWrapperService.resolveVerificationKey`. No new entity / migration / config: this is a pure routing change on top of the infrastructure that already shipped. ## Why `#20467` only flipped `ACCESS` and `REFRESH` to ES256. Every other JWT type was still HS256-signed against the global `APP_SECRET`, which kept the original blast radius (a leaked `APP_SECRET` invalidates every JWT type forever). Migrating the rest unifies the sign path on rotatable per-server private keys without forcing any token reissue. ## Mechanical changes ### Sign side (8 services) - `LoginTokenService.generateLoginToken` - `TransientTokenService.generateTransientToken` - `WorkspaceAgnosticTokenService.generateWorkspaceAgnosticToken` - `ApplicationTokenService.signApplicationToken` (`APPLICATION_ACCESS` + `APPLICATION_REFRESH`) - `ApiKeyService.generateApiKeyToken` - `FileUrlService.signFileByIdUrl` / `signWorkspaceLogoUrl` - `ConnectionProviderOAuthFlowService.signState` (`APP_OAUTH_STATE`) - `CodeInterpreterTool.generateSessionToken` Each call site swaps `jwtWrapperService.sign(payload, { secret: generateAppSecret(...), ... })` for `await jwtWrapperService.signAsync(payload, { expiresIn, [jwtid] })`. The `generateAppSecret` calls on the sign side are dropped (verifier-side `generateAppSecret` stays in `resolveVerificationKey` for the HS256 fallback). ### Verifier side - `WorkspaceAgnosticTokenService.validateToken` now goes through `verifyJwtToken` instead of the bespoke `verify({ secret })` path, so new ES256 tokens are accepted while the legacy HS256 fallback inside `resolveVerificationKey` still serves the old shape. - `JwtWrapperService.sign()` is kept (legacy compat / tests) but is now strictly deprecated — there are no remaining production callers. ### Async ripple (`signFileByIdUrl` was synchronous) - `FileUrlService.signFileByIdUrl` and `signWorkspaceLogoUrl` are now `async`; the `signUrl` callback used by `getRecordImageIdentifier` is widened to accept `Promise<string \| null>`. - Every direct/indirect caller is updated: admin panel (user lookup + statistics + top workspaces), search service (`computeSearchObjectResults`, `getImageIdentifierValue`), workspace resolver (`logo` resolver, public workspace by domain/id), `WorkspaceMemberTranspiler` (now `async toWorkspaceMemberDto[s]` / `toDeletedWorkspaceMemberDto[s]` / `generateSignedAvatarUrl`), `UserService.loadSignedAvatarUrlsByUserId`, `UserWorkspaceService.castWorkspaceToAvailableWorkspace`, workspace-invitation, approved-access-domain, agent-chat-streaming, agent-message-part resolver, navigation-menu-item record identifier, file-ai-chat / file-core-picture / file-email-attachment / file-workflow / files-field services, rich-text & files-field query result getters, and the code-interpreter tool. ## Backward compatibility - Legacy HS256 tokens (no `kid`) keep verifying via `resolveVerificationKey` → `extractAppSecretBody` → `generateAppSecret` for both `workspaceId`-bearing and `userId`-bearing payloads. - The `API_KEY` HS256-via-ACCESS-secret fallback (#16504) still kicks in inside `verifyJwtToken` for pre-2025-12-12 API keys. - No payload shape changes, no DB writes, no env var changes — old tokens issued by `main` continue to authenticate. ## Tests ### Unit (all green locally — 63/63) Updated specs for every migrated service to mock `signAsync` instead of `sign` and assert the new option shape: - `login-token.service.spec.ts`, `transient-token.service.spec.ts`, `workspace-agnostic-token.service.spec.ts`, `application-token.service.spec.ts`, `api-key.service.spec.ts`, `connection-provider-oauth-flow.service.spec.ts`. ### Integration (`jwt-key-rotation.integration-spec.ts`) - Existing ACCESS coverage (current key, legacy HS256 fallback, rotated-out key, revoked key, unknown kid) is preserved. - New `it.each` assertion: `REFRESH`, `WORKSPACE_AGNOSTIC`, and `LOGIN` tokens emitted by the real signUp → signUpInNewWorkspace → getAuthTokensFromLoginToken pipeline are ES256 with a `kid` matching the current signing key — proves end-to-end that the migration didn't regress those flows. ## Open question (separate decision) This PR keeps the legacy HS256 verification fallback forever. We may eventually want to sunset it for `API_KEY` once telemetry shows pre-migration tokens are gone, but that's a separate product/security decision and not part of this change. ## Test plan - [ ] CI green - [ ] `npx nx lint:diff-with-main twenty-server` passes - [ ] `npx nx typecheck twenty-server` passes - [ ] `jwt-key-rotation` integration suite passes (new + existing assertions) - [ ] Manually verify: signing in issues an ES256 ACCESS / REFRESH token, generating an API key issues an ES256 token with `kid`, signed file URL JWT is ES256 with `kid` - [ ] Pre-existing HS256 tokens still authenticate (covered by integration test, but worth a manual check with a token from `main`)	2026-05-13 10:53:45 +00:00

feat(admin-panel): signing keys management tab with usage tracking (#20586 )

## Summary
- Adds a new admin-only **Security** tab to the Admin Panel (alongside
General/Apps/AI/Config/Health) containing a **Signing Keys** section.
The tab is intentionally introduced now so the upcoming **Encryption
rotation** work can land as a sibling section.
- Lists every JWT signing key with key id, `createdAt`, `revokedAt`,
current/active/revoked status, and a **7-day verification count** read
from Redis. A trailing row aggregates **legacy HS256** verifications so
it is clear when the deprecated path is still in use.
- Lets an admin **revoke** a public key. Revoking the current key drops
`isCurrent`, sets `revokedAt`, nulls the encrypted `privateKey` and
clears the in-process cached current key; the existing lazy path in
`JwtKeyManagerService.getCurrentSigningKey()` then mints a fresh current
key on the next sign.

## Backend
- `SigningKeyVerifyCounterService` — bucketed Redis counter under the
existing `EngineMetrics` namespace. 1-day UTC-aligned buckets, 8-day TTL
refreshed on every increment, batched read via `mget`. Failures are
swallowed and logged at `warn` so a Redis hiccup cannot break auth.
- `JwtWrapperService.verifyJwtToken` records verifies **after success**
for both ES256 (`kid` as identifier) and HS256 (the literal `legacy`
identifier).
- `JwtKeyManagerService.listSigningKeys()` and `revokeSigningKey(id)`:
list ordered by `isCurrent DESC, createdAt DESC`; revoke is idempotent,
validates the UUID, invalidates the public-key cache, and resets the
cached current-key promise.
- `AdminPanelResolver.getSigningKeys` (query) and `revokeSigningKey`
(mutation) are both decorated with `@UseGuards(AdminPanelGuard)` so they
are admin-only, like the 35 existing admin-only methods on this
resolver. `privateKey` is never returned over GraphQL.

## Frontend
- New `SECURITY` tab id wired into `SettingsAdminContent` and
`SettingsAdminTabContent` (gated by `canAccessFullAdminPanel`).
- `SettingsAdminSecurity` / `SettingsAdminSigningKeysTable` strictly
reuse existing admin-panel components: `Section`, `H2Title`,
`Table`/`TableRow`/`TableCell`/`TableHeader` from `@/ui/layout/table`,
`Tag`/`Button` from `twenty-ui`, and `ConfirmationModal` mirroring the
queue retry/delete modals. Only one minimal styled helper for the
monospaced UUID rendering.
- `useRevokeSigningKey` uses `useApolloAdminClient`, refetches
`GetSigningKeys`, shows success/error snackbars (same pattern as
`useRetryJobs`/`useDeleteJobs`).

feat(server): migrate all remaining JWT token types to ES256 (#20513 )

## Summary

Extends the asymmetric signing work from #20467 to cover **every
remaining `JwtTokenTypeEnum` value**: `LOGIN`, `WORKSPACE_AGNOSTIC`,
`FILE`, `API_KEY`, `APPLICATION_ACCESS`, `APPLICATION_REFRESH`,
`APP_OAUTH_STATE`, plus the ACCESS-shaped session token issued by the
code interpreter tool.

After this PR, every JWT the server signs is ES256 with a `kid` pointing
at the current `core."signingKey"` row, while legacy HS256 tokens (no
`kid` header) remain verifiable indefinitely through the existing
fallback in `JwtWrapperService.resolveVerificationKey`. No new entity /
migration / config: this is a pure routing change on top of the
infrastructure that already shipped.

## Why

`#20467` only flipped `ACCESS` and `REFRESH` to ES256. Every other JWT
type was still HS256-signed against the global `APP_SECRET`, which kept
the original blast radius (a leaked `APP_SECRET` invalidates *every* JWT
type forever). Migrating the rest unifies the sign path on rotatable
per-server private keys without forcing any token reissue.

## Mechanical changes

### Sign side (8 services)
- `LoginTokenService.generateLoginToken`
- `TransientTokenService.generateTransientToken`
- `WorkspaceAgnosticTokenService.generateWorkspaceAgnosticToken`
- `ApplicationTokenService.signApplicationToken` (`APPLICATION_ACCESS` +
`APPLICATION_REFRESH`)
- `ApiKeyService.generateApiKeyToken`
- `FileUrlService.signFileByIdUrl` / `signWorkspaceLogoUrl`
- `ConnectionProviderOAuthFlowService.signState` (`APP_OAUTH_STATE`)
- `CodeInterpreterTool.generateSessionToken`

Each call site swaps `jwtWrapperService.sign(payload, { secret:
generateAppSecret(...), ... })` for `await
jwtWrapperService.signAsync(payload, { expiresIn, [jwtid] })`. The
`generateAppSecret` calls on the sign side are dropped (verifier-side
`generateAppSecret` stays in `resolveVerificationKey` for the HS256
fallback).

### Verifier side
- `WorkspaceAgnosticTokenService.validateToken` now goes through
`verifyJwtToken` instead of the bespoke `verify({ secret })` path, so
new ES256 tokens are accepted while the legacy HS256 fallback inside
`resolveVerificationKey` still serves the old shape.
- `JwtWrapperService.sign()` is kept (legacy compat / tests) but is now
strictly deprecated — there are no remaining production callers.

### Async ripple (`signFileByIdUrl` was synchronous)
- `FileUrlService.signFileByIdUrl` and `signWorkspaceLogoUrl` are now
`async`; the `signUrl` callback used by `getRecordImageIdentifier` is
widened to accept `Promise<string | null>`.
- Every direct/indirect caller is updated: admin panel (user lookup +
statistics + top workspaces), search service
(`computeSearchObjectResults`, `getImageIdentifierValue`), workspace
resolver (`logo` resolver, public workspace by domain/id),
`WorkspaceMemberTranspiler` (now `async toWorkspaceMemberDto[s]` /
`toDeletedWorkspaceMemberDto[s]` / `generateSignedAvatarUrl`),
`UserService.loadSignedAvatarUrlsByUserId`,
`UserWorkspaceService.castWorkspaceToAvailableWorkspace`,
workspace-invitation, approved-access-domain, agent-chat-streaming,
agent-message-part resolver, navigation-menu-item record identifier,
file-ai-chat / file-core-picture / file-email-attachment / file-workflow
/ files-field services, rich-text & files-field query result getters,
and the code-interpreter tool.

## Backward compatibility

- **Legacy HS256 tokens (no `kid`)** keep verifying via
`resolveVerificationKey` → `extractAppSecretBody` → `generateAppSecret`
for both `workspaceId`-bearing and `userId`-bearing payloads.
- The `API_KEY` HS256-via-ACCESS-secret fallback (#16504) still kicks in
inside `verifyJwtToken` for pre-2025-12-12 API keys.
- No payload shape changes, no DB writes, no env var changes — old
tokens issued by `main` continue to authenticate.

## Tests

### Unit (all green locally — 63/63)
Updated specs for every migrated service to mock `signAsync` instead of
`sign` and assert the new option shape:
- `login-token.service.spec.ts`, `transient-token.service.spec.ts`,
`workspace-agnostic-token.service.spec.ts`,
`application-token.service.spec.ts`, `api-key.service.spec.ts`,
`connection-provider-oauth-flow.service.spec.ts`.

### Integration (`jwt-key-rotation.integration-spec.ts`)
- Existing ACCESS coverage (current key, legacy HS256 fallback,
rotated-out key, revoked key, unknown kid) is preserved.
- New `it.each` assertion: `REFRESH`, `WORKSPACE_AGNOSTIC`, and `LOGIN`
tokens emitted by the real signUp → signUpInNewWorkspace →
getAuthTokensFromLoginToken pipeline are ES256 with a `kid` matching the
current signing key — proves end-to-end that the migration didn't
regress those flows.

## Open question (separate decision)

This PR keeps the legacy HS256 verification fallback **forever**. We may
eventually want to sunset it for `API_KEY` once telemetry shows
pre-migration tokens are gone, but that's a separate product/security
decision and not part of this change.

## Test plan

- [ ] CI green
- [ ] `npx nx lint:diff-with-main twenty-server` passes
- [ ] `npx nx typecheck twenty-server` passes
- [ ] `jwt-key-rotation` integration suite passes (new + existing
assertions)
- [ ] Manually verify: signing in issues an ES256 ACCESS / REFRESH
token, generating an API key issues an ES256 token with `kid`, signed
file URL JWT is ES256 with `kid`
- [ ] Pre-existing HS256 tokens still authenticate (covered by
integration test, but worth a manual check with a token from `main`)

feat(server): asymmetric JWT signing with kid + key rotation table (#20467 )

## Context

Today every JWT issued by Twenty (access, refresh, login, file, etc.) is
HMAC-signed with a per-token-type secret derived from the global
`APP_SECRET`. Rotating that secret invalidates **every** active token at
once and there is no way to scope a leak to a subset of tokens.

This PR is the first slice of a broader effort to **decouple stateful
encryption (`APP_SECRET`-derived secrets) from stateless encryption
(JWTs)**. It introduces an asymmetric (private/public key) signing path
for `ACCESS` and `REFRESH` tokens and a signing-key registry to enable
**safe rotation**: leaked keys can be revoked by flipping
`revokedAt`/`isCurrent` on the matching row without invalidating tokens
issued by other keys.

> Out of scope (intentionally): swapping stateful encryption for
`APP_SECRET`, asymmetric signing for token types other than
`ACCESS`/`REFRESH`, an admin-panel rotation UI, and an enterprise
re-encryption command. Those will land in follow-up PRs.

## What changes

- **New `core.signingKey` table** (instance command `2.5.0` /
`1778550000000`) storing both the public key (PEM, in clear) and the
private key (PEM, encrypted with `APP_SECRET` via
`SecretEncryptionService`). One row is marked `isCurrent = true`
(enforced by a partial unique index). The row's UUID `id` is used
directly as the JWT `kid`.
- When a key is rotated out, its `privateKey` is nulled (we never keep
historical private keys) but the `publicKey` row stays so previously
issued tokens can still be verified.
- **`JwtKeyManagerService`** lazily loads-or-generates the current
signing key on first use:
  - If a row with `isCurrent = true` exists → decrypts and uses it.
- Otherwise → generates a fresh EC P-256 keypair, encrypts the private
key, inserts the row (UUID id = kid). Handles concurrent insert races
via the unique constraint.
- **`JwtWrapperService.signAsync()`** signs `ACCESS`/`REFRESH` payloads
with `ES256` and a `kid` header. Falls back to `HS256` if no signing key
is available (boot-time DB error, transient failure).
- **Dual-path verification** in both `JwtWrapperService.verifyJwtToken`
and the Passport `JwtAuthStrategy.secretOrKeyProvider`:
- JWT with a `kid` header → resolve the public key PEM by id and verify
with `ES256`,
- otherwise → fall back to the existing `APP_SECRET`-derived `HS256`
path (unchanged).
- **`AccessTokenService` / `RefreshTokenService`** now sign through
`signAsync` (single public surface; the routing detail stays internal to
the wrapper).
- **Public key cache**: a new `SigningKeyEntityCacheProviderService`
plugs into `CoreEntityCacheService` (`signingKeyPublicKey` namespace)
and serves PEMs by id, with the standard local-memo + Redis layering.
- **PEM strings end-to-end**: `jsonwebtoken` accepts PEM strings
directly for both sign and verify, so the manager never converts to a
Node `KeyObject` and the cache hands the PEM straight to `jwt.verify`.

## Why ES256 (and not EdDSA / RS256)

- `@nestjs/jwt` is backed by `jsonwebtoken`, which does **not** support
EdDSA today.
- ES256 keys are tiny (~120 bytes vs 1.6 kB for RS256), signatures are
short (~64 bytes), and signing/verification is fast — important since
JWT verification runs on every authenticated request.
- ES256 is widely supported and standardized (RFC 7518), with mature
ecosystem support.

## Why store the private key in DB (not env)

- No new secret to provision: existing instances already have
`APP_SECRET`, which we reuse to encrypt the private key at rest.
- Self-healing: a fresh instance auto-generates its first signing key on
first boot. Nothing to copy/paste.
- Rotation is a SQL operation against `core.signingKey`, not a redeploy
+ env mutation.

## Backward compatibility

- All previously-issued tokens (no `kid`) keep verifying through the
legacy HS256 path with their existing `APP_SECRET`-derived secret. No
forced re-login.
- Token types not in scope (`WORKSPACE_AGNOSTIC`, `API_KEY`, `FILE`,
`LOGIN`, `EMAIL_VERIFICATION`, etc.) keep their current HS256 behavior
unchanged — they still go through the synchronous
`JwtWrapperService.sign(payload, options)` with a caller-supplied
secret.
- `signWithAppSecret` is kept intentionally as the HS256 fallback path;
it will be deprecated in a follow-up PR.
- If the DB lookup/generation fails for any reason, the wrapper logs the
error and falls back to HS256 — no startup crash, no silent regression.

## Rotation story

1. Bootstrap: first signing call lazily inserts a row in
`core.signingKey` with `isCurrent = true`, `privateKey =
encrypt(pem_A)`. New tokens carry `kid_A`.
2. Rotate: `UPDATE core."signingKey" SET "isCurrent" = false,
"privateKey" = NULL WHERE id = '<kid_A>';` then insert a new row with
`isCurrent = true`. New tokens carry `kid_B`. Tokens still in flight
with `kid_A` keep verifying because the public-key row for `kid_A` is
still there.
3. Revoke: `UPDATE core."signingKey" SET "revokedAt" = now() WHERE id =
'<kid_A>';`. All tokens with `kid_A` now fail verification cleanly with
`UNAUTHENTICATED` (no 500).
4. Tokens with no `kid` (legacy) are unaffected throughout.

## Test plan

- [x] Unit: `JwtWrapperService` dual-path verification (HS256 no-kid vs
ES256 with-kid), unknown-kid → `UNAUTHENTICATED`, `signAsync` happy path
+ `null` when no key, `signAsync` rejection for non-rotatable types.
- [x] Unit: `JwtAuthStrategy` `secretOrKeyProvider` dual-path resolution
and algorithm validation.
- [x] All existing JWT/auth/application unit tests adjusted to the
renamed public method.
- [x] Integration (`jwt-key-rotation.integration-spec.ts`):
- **Happy path**: signed-up user's `ACCESS` token has `alg=ES256` +
correct UUID `kid`, the `isCurrent=true` row exists in
`core.signingKey`, `getCurrentUser` resolves.
- **Legacy fallback**: hand-crafted no-kid HS256 token verifies via the
legacy `APP_SECRET`-derived path.
- **Previous-key rotation**: token signed by a hardcoded *previous* key
whose row is pre-inserted with `privateKey = NULL` (rotated-out) still
verifies — proves the leaked-key revocation flow works in both
directions.
- **Unknown kid**: token signed with an orphan UUID `kid` is cleanly
rejected (no 500).
