+## PostgreSQL TLS 加固
+
+- 推荐将数据库域名单独设置为 `db.refining.ltd`，服务域名保持 `secrets.refining.app`。
+- 数据库证书建议使用可校验链路（如 Let's Encrypt 或私有 CA），并保证证书 `SAN` 包含 `db.refining.ltd`。
+- PostgreSQL 侧建议使用 `hostssl` 规则限制应用来源（如 `47.238.146.244/32`），逐步移除公网明文 `host` 访问。
+- 应用端推荐 `SECRETS_DATABASE_SSL_MODE=verify-full`；仅在过渡阶段可临时用 `verify-ca`。
+- 可执行运维步骤见 [`deploy/postgres-tls-hardening.md`](deploy/postgres-tls-hardening.md)。

 条目在逻辑上以 **`(folder, name)`** 在用户内唯一（数据库唯一索引：`user_id + folder + name`）。同名可在不同 folder 下各存一条（例如 `refining/aliyun` 与 `ricnsmart/aliyun`）。
 
-- **`secrets_search`**：发现条目（可按 query / folder / type / name 过滤）；不要求加密头。
+### 工具列表
-- **`secrets_get` / `secrets_update` / `secrets_delete`（按 name）/ `secrets_history` / `secrets_rollback`**：仅 `name` 且全局唯一则直接命中；若多条同名，返回消歧错误，需在参数中补 **`folder`**。
+
-- **`secrets_delete`**：`dry_run=true` 时与真实删除相同的消歧规则——唯一则预览一条，多条则报错并要求 `folder`。
+| 工具 | 需要加密密钥 | 说明 |
+|------|-------------|------|
+| `secrets_find` | 否 | 发现条目（返回含 secret_fields schema），支持 `name_query` 模糊匹配 |
+| `secrets_search` | 否 | 搜索条目，支持 `query`/`folder`/`type`/`name` 过滤、`sort`/`offset` 分页、`summary` 摘要模式 |
+| `secrets_get` | 是 | 按 UUID `id` 获取单条条目及解密后的 secrets |
+| `secrets_add` | 是 | 添加新条目，支持 `meta_obj`/`secrets_obj` JSON 对象参数、`secret_types` 指定密钥类型、`link_secret_names` 关联已有 secret |
+| `secrets_update` | 是 | 更新条目，支持 `id` 或 `name`+`folder` 定位 |
+| `secrets_delete` | 否 | 删除条目，支持 `id` 或 `name`+`folder` 定位；`dry_run=true` 预览删除 |
+| `secrets_history` | 否 | 查看条目历史，支持 `id` 或 `name`+`folder` 定位 |
+| `secrets_rollback` | 是 | 回滚条目到指定历史版本，支持 `id` 或 `name`+`folder` 定位 |

+| `secrets_env_map` | 是 | 将 secrets 转换为环境变量映射（`UPPER(entry)_UPPER(field)` 格式），支持 `prefix` |
+| `secrets_overview` | 否 | 返回各 folder 和 type 的 entry 计数概览 |
+
+### 消歧规则
+
+- **按 `name` 定位的工具**（`secrets_update` / `secrets_delete` / `secrets_history` / `secrets_rollback`）：若该用户下仅一条匹配则直接执行；若多条（同 `name`、不同 `folder`）则返回错误并提示补全 `folder`。也可直接传 `id`（UUID）跳过消歧。
+- **`secrets_get`** 仅支持通过 `id`（UUID）获取。
+- **`secrets_delete`** 的 `dry_run=true` 与真实删除使用相同消歧规则——唯一则预览一条，多条则报错并要求 `folder`。
+
+### 共享密钥
+
+N:N 关联下，删除 entry 仅解除关联，被共享的 secret 若仍被其他 entry 引用则保留；无引用时自动清理。

+# PostgreSQL TLS Hardening Runbook
+
+This runbook applies to:
+
+- PostgreSQL server: `47.117.131.22` (`db.refining.ltd`)
+- `secrets-mcp` app server: `47.238.146.244` (`secrets.refining.app`)
+
+## 1) Issue certificate for `db.refining.ltd` (Let's Encrypt + Cloudflare DNS-01)
+
+Install `acme.sh` on the PostgreSQL server and use a Cloudflare API token with DNS edit permission for the target zone.
+
+```bash
+curl https://get.acme.sh | sh -s email=ops@refining.ltd
+export CF_Token="your_cloudflare_dns_token"
+export CF_Zone_ID="your_zone_id"
+~/.acme.sh/acme.sh --issue --dns dns_cf -d db.refining.ltd --keylength ec-256
+```
+
+Install cert/key into a PostgreSQL-readable path:
+
+```bash
+sudo mkdir -p /etc/postgresql/tls
+sudo ~/.acme.sh/acme.sh --install-cert -d db.refining.ltd --ecc \
+  --fullchain-file /etc/postgresql/tls/fullchain.pem \
+  --key-file /etc/postgresql/tls/privkey.pem \
+  --reloadcmd "systemctl reload postgresql || systemctl restart postgresql"
+sudo chown -R postgres:postgres /etc/postgresql/tls
+sudo chmod 600 /etc/postgresql/tls/privkey.pem
+sudo chmod 644 /etc/postgresql/tls/fullchain.pem
+```
+
+## 2) Configure PostgreSQL TLS and access rules
+
+In `postgresql.conf`:
+
+```conf
+ssl = on
+ssl_cert_file = '/etc/postgresql/tls/fullchain.pem'
+ssl_key_file = '/etc/postgresql/tls/privkey.pem'
+```
+
+In `pg_hba.conf`, allow app traffic via TLS only (example):
+
+```conf
+hostssl  secrets-mcp  postgres  47.238.146.244/32  scram-sha-256
+```
+
+Keep a safe admin path (`local` socket or restricted source CIDR) before removing old plaintext `host` rules.
+
+Reload PostgreSQL:
+
+```bash
+sudo systemctl reload postgresql
+```
+
+## 3) Verify server-side TLS
+
+```bash
+openssl s_client -starttls postgres -connect db.refining.ltd:5432 -servername db.refining.ltd
+```
+
+The handshake should succeed and the certificate should match `db.refining.ltd`.
+
+## 4) Update `secrets-mcp` app server env
+
+Use environment values like:
+
+```bash
+SECRETS_DATABASE_URL=postgres://postgres:***@db.refining.ltd:5432/secrets-mcp
+SECRETS_DATABASE_SSL_MODE=verify-full
+SECRETS_ENV=production
+```
+
+If you use private CA instead of public CA, also set:
+
+```bash
+SECRETS_DATABASE_SSL_ROOT_CERT=/etc/secrets/pg-ca.crt
+```
+
+Restart `secrets-mcp` after updating env.
+
+## 5) Verify from app server
+
+Run positive and negative checks:
+
+- Positive: app starts, migrations pass, dashboard + MCP API work.
+- Negative:
+  - wrong hostname -> connection fails
+  - wrong CA file -> connection fails
+  - disable TLS on DB -> connection fails
+
+This ensures no silent downgrade to weak TLS in production.
