### 使用SFCS读写模型并启用加解密 ### 读写模型时启用加解密
该库可以读写 SFCS 上的模型文件，在此情况下可以启用加解密能力。读写 SFCS 上的模型文件和加解密所需的敏感信息，有两种获取方式：(1) 火山引擎可信服务的 unix domain socket，(2) 环境变量。在没有挂载可信服务 uds 的情况下，可以使用下面的环境变量： 该库底层通过两种接口读写：SFCS SDK 和 POSIX。如果文件路径前缀为 `sfcs://` 就视为使用 SFCS SDK，所需的鉴权信息可以从火山引擎可信服务的 unix domain socket 获取， 或者设置以下三个环境变量：
| 环境变量名 | 含义 | | 环境变量名 | 含义 |
| ------------------------------ | --------------------------------- | | ------------------------------ | --------------------------------- |
| SFCS_ACCESS_KEY | SFCS文件系统的AK | | SFCS_ACCESS_KEY | SFCS 文件系统的 AK |
| SFCS_SECRET_KEY | SFCS文件系统的SK | | SFCS_SECRET_KEY | SFCS 文件系统的 SK |
| SFCS_NAMENODE_ENDPOINT_ADDRESS | SFCS文件系统name节点地址 | | SFCS_NAMENODE_ENDPOINT_ADDRESS | SFCS 文件系统 name 节点地址 |
| VETUROIO_KEY | 加解密的128位数据密钥的base64编码 |
| VETUROIO_IV | 加解密的128位初始向量的base64编码 |
挂载可信服务 uds 或者配置好环境变量后，可以参考下面代码在读写 SFCS 上的模型文件时启用加解密： 加解密读写模型文件所需的 data key 和 iv，共有3种获取方式，优先级按照序号：
- [1] 加密的 data key 和 iv 存放在密文模型文件的 header 中，使用火山引擎 KMS 解密得到明文的 data key。
- [1.1] 访问 KMS 所需的 AK/SK/ST 从火山引擎可信服务的 unix domain socket 获取，需要额外挂载。
- [1.2] 访问 KMS 所需的 AK/SK/ST 从环境变量获取。
- [2] 访问火山引擎可信服务的 unix domain socket 直接获取 data key 和 iv，需要额外挂载。
- [3] 环境变量直接设置 data key 和 iv。
不同方式需要设置的环境变量如下：
| 环境变量名 | 含义 |
| ------------------------------ | --------------------------------- |
| VETURBOIO_KMS_HOST | [1] KMS 服务地址，默认值 open.volcengineapi.com|
| VETURBOIO_KMS_REGION | [1] KMS 服务所在区域，默认值 cn-beijing |
| VETURBOIO_KMS_KEYRING_NAME | [1] KMS 服务解密 data key 的钥匙环名 |
| VETURBOIO_KMS_KEY_NAME | [1] KMS 服务解密 data key 的主密钥名 |
| DATAPIPE_SOCKET_PATH | [1.1][2] 可信服务 uds 的路径 |
| VETURBOIO_KMS_ACCESS_KEY | [1.2] KMS 鉴权的 AK |
| VETURBOIO_KMS_SECRET_KEY | [1.2] KMS 鉴权的 SK |
| VETURBOIO_KMS_SESSION_TOKEN | [1.2] KMS 鉴权的临时令牌，非必需|
| VETURBOIO_KEY | [3] 加解密的 128 位数据密钥的 base64 编码 |
| VETURBOIO_IV | [3] 加解密的 128 位初始向量的 base64 编码 |
按照上述三种方式设置好后，可以参考下面代码在读写模型文件时启用加解密：
