6.13. 设置新主密钥

过程 6.2. 生成并传输 Wrapped 主密钥

1. 获取访问 Token Key Service 安全数据库所需的内部 PIN：

   # cat /var/lib/pki/pki-tomcat/tks/conf/password.conf
   
   internal=649713464822
   internaldb=secret12
   replicationdb=-752230707

2. 打开 TKS 实例 别名/ 目录：

   # cd /var/lib/pki/pki-tomcat/alias

   Copy to Clipboard Toggle word wrap
3. 创建名为 transport 的 传输 密钥：

   # tkstool -T -d . -n transport

   Copy to Clipboard Toggle word wrap
   注意
   tkstool 程序输出每个生成的三个会话键的密钥共享和 KCV 值。将这些文件保存到文件中，因为稍后会在这个流程中的新数据库中重新生成传输密钥，并在丢失密钥时重新生成密钥。
4. 出现提示时，填写数据库密码。然后，根据屏幕的说明生成随机 seed。

   A random seed must be generated that will be used in the
   creation of your key.  One of the easiest ways to create a
   random seed is to use the timing of keystrokes on a keyboard.
   
   To begin, type keys on the keyboard until this progress meter
   is full.  DO NOT USE THE AUTOREPEAT FUNCTION ON YOUR KEYBOARD!
   
   
   Continue typing until the progress meter is full:
   
   |************************************************************|
   
   Finished.
   
   
   Type the word "proceed" and press enter

5. 下一提示将生成一系列会话密钥。按照屏幕说明操作，直到最终消息：

   Successfully generated, stored, and named the transport key!

6. 使用 transport 密钥生成并打包一个 master 密钥，并将其存储在名为 的文件 ：

   # tkstool -W -d . -n new_master -t transport -o file 
   Enter Password or Pin for "NSS Certificate DB":
   Retrieving the transport key (for wrapping) from the specified token . . .
   Generating and storing the master key on the specified token . . .
   Naming the master key "new_master" . . .
   Successfully generated, stored, and named the master key!
   Using the transport key to wrap and store the master key . . .
   Writing the wrapped data (and resident master key KCV) into the
    file called "file" . . .
   
          wrapped data:   47C0 06DB 7D3F D9ED
                          FE91 7E6F A7E5 91B9
          master key KCV: CED9 4A7B
          (computed KCV of the master key residing inside the wrapped data)

7. 将嵌套的 master 密钥复制到适当的位置或工具中。
8. 如有必要，在 HSM 或设备中生成新安全数据库：

   # tkstool -N -d <directory>

   Copy to Clipboard Toggle word wrap
   或者，添加 -I 选项来生成与最初在新数据库中生成的键相同。以这种方式重新生成 transport 密钥需要您输入会话密钥共享和 KCV，用于这个过程早期生成的每个会话密钥。

   # tkstool -I -d <directory> -n verify_transport

9. 使用 transport 密钥来取消包装存储在 文件中的主密钥。提示时提供安全数据库 PIN：

   # tkstool -U -d directory -n new_master -t verify_transport -i file
   Enter Password or Pin for "NSS Certificate DB":
   Retrieving the transport key from the specified token (for
    unwrapping) . . .
   Reading in the wrapped data (and resident master key KCV) from
    the file called "file" . . .
   
        wrapped data:   47C0 06DB 7D3F D9ED
                        FE91 7E6F A7E5 91B9
        master key KCV: CED9 4A7B
        (pre-computed KCV of the master key residing inside the wrapped data)
   
   Using the transport key to temporarily unwrap the master key to
   recompute its KCV value to check against its pre-computed KCV value . . .
        master key KCV: CED9 4A7B
        (computed KCV of the master key residing inside the wrapped data)
        master key KCV: CED9 4A7B
        (pre-computed KCV of the master key residing inside the wrapped data)
   
   Using the transport key to unwrap and store the master key on the
    specified token . . .
   Naming the master key "new_master" . . .
   Successfully unwrapped, stored, and named the master key!

10. 验证密钥是否已正确添加到数据库中：

    # tkstool -L -d
    slot:  NSS User Private Key and Certificate Services
    token:  NSS Certificate DB
    
    Enter Password or Pin for "NSS Certificate DB":
    			 <0> transport
    			 <1> new_master
