CA-KEY
Perform batch deletion of the CA certificate and key pair.
When a serviceman replaces or disposes of a device, he/she must perform batch deletion of the
CA certificate and key pair. The CA certificate is used by MEAP application which uses E-RDS,
and SSL client connection. The key pair is used by IPP, RUI, and MEAP SSL function.
- If this operation is not performed when a device is replaced or disposed of, the CA certificate
and key pair additionally registered by a user remains in the HDD, which causes a security
problem. Therefore, a serviceman must perform this operation.
- Be sure to make sure that OK is displayed after the operation is performed. When NG is
displayed, the CA certificate and key pair may have not been normally deleted. Therefore, it is
necessary to surely delete them by initializing the HDD, etc.
- When this operation is performed, the SSL server certificate and key pair additionally registered
by a user are also deleted. Therefore, do not perform this operation carelessly. If you have deleted
the data by mistake, you need to ask the user to reinstall the SSL server certificate. If no certificate
is additionally installed by a user, the setting values are initialized to be the same as the factory
setting, and there is no impact to the user.
Operation method
1) Select this item and press the OK key.
2) When the data is cleared normally, OK is displayed.

Reference:
When the power is turned OFF/ON, the CA certificate and key pair are extracted from the archive
(/BOOTDEV/KCMNG) and become available for the function mentioned above (E-RDS/SSL
function).
