恢复原始私钥（Hard Key Recovery）

适用场景

Cobo MPC Co-Managed Custody 发生不可抗力因素导致无法再为客户提供服务。

这时，客户可以通过自身及其委托的第三方所管理的两个私钥分片，恢复出 MPC 钱包对应的 MPC 根扩展私钥（ MPC Root Extended Private Key），并且基于此根扩展私钥推导出 MPC 钱包内所有地址的私钥。恢复每个地址的私钥需要依赖下方所述的准备工作，如果客户在平时正确完成了准备工作的内容，整个私钥恢复过程是完全不需要 Cobo 参与的。

条件要求

客户及其委托的第三方维护的两个 TSS Node 的 secrets.db 数据文件及密码
完成下列前期准备工作

前期准备工作

恢复原始私钥（Hard Key Recovery）所使用的恢复工具为开源项目，名为 cobo-mpc-recovery-kits，链接地址为 https://github.com/CoboCustody/cobo-mpc-recovery-kits 。打开链接后，阅读工程 README.md，下载或编译私钥恢复工具 cobo-mpc-recovery-tool ，客户可前往 https://github.com/CoboCustody/cobo-mpc-recovery-kits/releases 下载最新发布的版本。
在三方协同生成 MPC 私钥分片之后，记录下本企业账号的 MPC 根扩展公钥（MPC Root Extended Public Key）。注意，根扩展公钥一旦生成后则不会改变，因此记录一次即可。
实时或者定时保存 MPC 钱包内的地址信息。可以通过三种方式获得地址的详细信息：

通过 API 的 generate_addresses 接口生成地址时，在返回的 AddressDetail 里有 hd_path 信息，客户需要将其和新生成的地址一并保存
通过 API 的 list_addresses 接口，获取所有地址的 AddressDetail 信息，其中含有每个地址对应的 hd_path 信息
通过 Cobo Custody Web 的导出按钮，人工导出 MPC 钱包下的所有地址信息，如下图红框所示：

上述步骤中的第 1 、2 步都是一次性的，第 3 步则是在每个新地址生成后都需要进行一次，请客户结合自己的业务场景合理执行准备工作。

恢复过程

准备恢复环境

客户需确保其管理 TSS Node 的主机均处于离线或者安全的网络环境下，并且操作员及其操作电脑、显示器等操作设备也都处于安全的环境内。准备好 TSS Node 软件包与数据库文件，TSS Node 的目录结构如下：

cobo-tss-node-generic
├── configs
│   └── cobo-tss-node-config.yaml.template
├── db
│   └── secrets.db
├── recovery  （导出私钥分片所在的文件夹，无需手动新建）
└── tss-node.sh

确认私钥分片正确性

进入操作目录 cobo-tss-node-generic，获取 Group 信息

sudo ./tss-node.sh info group

示例：

$ sudo ./tss-node.sh info group

请确认上述日志中打印的 MPC Root Extended Public Key 和准备工作中第 2 步保存的 MPC Root Extended Public Key 是一致的。

如果一个 TSS Node 管理了多个私钥分片，请找到 MPC Root Extended Public Key 正确、并且更新时间最新的一组 Group 信息。随后记录下对应的 Group ID，例如上述日志中的 OoQGkknsPdPjLCmSuuSf。

将需要导出的私钥分片对应的 Group ID 和 Root Extended Public Key 提供给第三方，用于第三方核对私钥分片信息
导出私钥分片

客户在管理的 TSS Node 的根路径内，执行如下命令，导出私钥分片（其中的 <groupID> 请替换成前一步中获得的 Group ID）：

./tss-node.sh export-share --group-ids <groupID>

示例：

./tss-node.sh export-share --group-ids OoQGkknsPdPjLCmSuuSf

程序执行流程：

输入数据加密密码
新生成密码并重复输入，此密码用于对导出文件中的私钥分片进行加密，后续 Hard Key Recovery 过程需要输入此密码才能访问私钥分片数据；密码设置后不可修改；如果密码丢失，等同于导出的私钥分片文件失效，需要重新导出一次。请严格控制此密码的访问权限；推荐使用密码管理软件（例如 1Password）生成复杂密码，长度建议在16～32位
程序自动生成私钥分片文件，命名规则为 recovery/recovery-secrets-<nodeID>-<time>；私钥分片文件为 JSON 格式，例如上面日志中的 recovery/recovery-secrets-cobo2Jitd83uNFZmGnvs8c4Bs1TUNjVVeBQmc82a4KpLFqdbLs-2023-01-16T16:57:20Z
导出后，需要手动核对 JSON 文件对象 “group_info” 中的键 “id” 和键 “root_extended_public_key” 的值，确认是否正确。私钥分片文件示例如下：

接收第三方导出的私钥分片，并验证所有私钥分片是否合法

第三方导出私钥的方式与客户的类似，私钥分片文件为 JSON 格式，导出后，需要核对双方文件中的 Group ID 和 Root Extended Public Key 是否一致。

接下来，验证第三方导出的私钥分片与客户导出的私钥分片是否合法。在恢复工具 cobo-mpc-recovery-tool 同级目录下新建 recovery 文件夹，将两组私钥分片文件拷贝到 recovery 文件夹下，结构如下：

├── cobo-mpc-recovery-tool
└── recovery
    ├── recovery-secrets-<nodeID1>-<time1>
    └── recovery-secrets-<nodeID2>-<time2>

执行命令（请替换成真实的 Group ID 与私钥分片文件）：

./cobo-mpc-recovery-tool verify \
    --recovery-group-files recovery/recovery-secrets-<nodeID1>-<time1>,recovery/recovery-secrets-<nodeID2>-<time2> \
    --group-id <groupID>

示例：

程序执行过程：

检查第一个私钥分片文件的每项键/值是否合法
使用第一个私钥分片文件中“participants” 对象的信息，恢复根扩展公钥，检查与文件中的根扩展公钥是否一致。
手动输入第一个私钥分片文件的加密密码，解密出分片的私钥，然后推导出对应公钥，检查与文件中分片的公钥（share_public_key）是否一致
检查第二个私钥分片文件的每项键/值是否合法
检查第二个私钥分片文件中每项键/值与第一个私钥分片文件中每项键/值是否正确匹配
使用第二个私钥分片文件中所有参与者 “participants” 对象的信息，恢复根扩展公钥，检查与文件中的根扩展公钥是否一致。
手动输入第二个私钥分片文件的加密密码，解密出分片的私钥，然后推导出对应公钥，检查与文件中分片的公钥（share_public_key）是否一致。

合并私钥分片，恢复出 MPC Root Extended Private Key，推导出所有地址的私钥

准备工作第 3 步中介绍了多种记录地址信息的方式，本节以通过 Cobo Custody Web 导出的地址信息为例进行说明。如果客户计划使用自行保存的地址信息，请将地址信息按照相同的文件格式进行保存后再使用。

解压从 Cobo Custody Web 导出的压缩包后，可以看到 address.csv 文件；复制 address.csv 文件到与 cobo-mpc-recovery-tool 同级的 recovery 文件夹下，目录结构如下：

├── cobo-mpc-recovery-tool
└── recovery
    ├── address.csv
    ├── recovery-secrets-<nodeID1>-<time1>
    └── recovery-secrets-<nodeID2>-<time2>

执行命令（请替换成真实的 Group ID 与私钥分片文件）：

./cobo-mpc-recovery-tool \
    --recovery-group-files recovery/recovery-secrets-<nodeID1>-<time1>,recovery/recovery-secrets-<nodeID2>-<time2> \
    --group-id <groupID> \
    --csv-file recovery/address.csv \
    --show-root-private-key

示例：

./cobo-mpc-recovery-tool \
    --recovery-group-files recovery/recovery-secrets-cobo2Jitd83uNFZmGnvs8c4Bs1TUNjVVeBQmc82a4KpLFqdbLs-2023-01-16T16:57:20Z,recovery/recovery-secrets-cobok1nJ4P8DL1mU5SDEzh8QDA5FzdSg7gdkAZKUWK4NuviS4-2023-01-09T17:43:49Z \
    --group-id OoQGkknsPdPjLCmSuuSf \
    --csv-file recovery/address.csv \
    --show-root-private-key

程序执行过程：

按提示依次输入两个私钥分片文件的解密密码
根私钥合成成功后，会打印恢复出的 MPC Root Extended Private Key 和 MPC Root Extended Public Key
请确认 MPC Root Extended Public Key 和准备工作第 2 步中记录的一致
导入 address.csv 文件，根据文件中的 HD path 派生公钥与私钥，程序会自动生成文件 recovery/address-recovery-<time>.csv ，例如上面日志中的recovery/address-recovery-20230116-225417.csv

执行完成后，recovery/address-recovery-<time>.csv 文件内会包含所有地址的私钥明文信息。这些私钥可以直接用来管理加密资产，请妥善保管。
