## YML文件MYSQL密码加密存储手册

### 1、本地部署加密

**第一步:生成密文**

在本地仓库中找到jasypt-1.9.3.jar,默认在org/jasypt/jasypt/1.9.3中,使用`java -cp`生成密文。

```bash
java -cp jasypt-1.9.3.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input=mysql密码 password=加密的salt algorithm=PBEWithMD5AndDES
```

```bash
## 得到密文
DYbVDLg5D0WRcJSCUGWjiw==
```

**第二步:配置jasypt**

在YML文件中配置jasypt,例如

```yaml
jasypt:
encryptor:
algorithm: PBEWithMD5AndDES
iv-generator-classname: org.jasypt.iv.NoIvGenerator
```
**第三步:配置密文**
使用密文替换YML文件中的明文密码为ENC(密文),例如[application.yml](https://github.com/didi/KnowStreaming/blob/master/km-rest/src/main/resources/application.yml)中MYSQL密码。
```yaml
know-streaming:
username: root
password: ENC(DYbVDLg5D0WRcJSCUGWjiw==)
```
**第四步:配置加密的salt(选择其一)**
- 配置在YML文件中(不推荐)
```yaml
jasypt:
encryptor:
password: salt
```
- 配置程序启动时的命令行参数
```bash
java -jar xxx.jar --jasypt.encryptor.password=salt
```

- 配置程序启动时的环境变量

```bash
export JASYPT_PASSWORD=salt
java -jar xxx.jar --jasypt.encryptor.password=${JASYPT_PASSWORD}
```

## 2、容器部署加密

利用docker swarm 提供的 secret 机制加密存储密码,使用docker swarm来管理密码。

### 2.1、secret加密存储

**第一步:初始化docker swarm**

```bash
docker swarm init
```

**第二步:创建密钥**

```bash
echo "admin2022_" | docker secret create mysql_password -

# 输出密钥
f964wi4gg946hu78quxsh2ge9
```

**第三步:使用密钥**

```yaml
# mysql用户密码
SERVER_MYSQL_USER: root
SERVER_MYSQL_PASSWORD: mysql_password

knowstreaming-mysql:
# root 用户密码
MYSQL_ROOT_PASSWORD: mysql_password
secrets:
mysql_password:
external: true
```
### 2.2、使用密钥文件加密
**第一步:创建密钥**
```bash
echo "admin2022_" > password
```

**第二步:使用密钥**

```yaml
# mysql用户密码
SERVER_MYSQL_USER: root
SERVER_MYSQL_PASSWORD: mysql_password
secrets:
mysql_password:
file: ./password
```
