Preparation before using Forced Strong Key mode
When you use Forced Strong Key mode, the following conditions must be met:
-
Install HULFT with the product key that includes HULFT Cipher Option (AES)
-
Set "1" (Use Encryption Scheme of Cipher Option) for Encryption Scheme (CIPHERTYPE) in the System Environment Settings
If "1" (Enabled) is set for Forced Strong Key mode (STRONGKEYMODE) in the System Environment Settings but HULFT Cipher Option (AES) is not installed, HULFT becomes unable to start.
If you have removed or added a Cipher Option license from/to HULFT using a Product Key Update, Forced Strong Key Mode (STRONGKEYMODE) in the System Environment Settings must be changed accordingly to the change of your HULFT environment.
When you use Forced Strong Key mode
Check Forced Strong Key mode (STRONGKEYMODE) in the System Environment Settings.
If "0" (Disabled) is set, change it to "1" (Enabled).
When you do not use Forced Strong Key mode
Check Forced Strong Key mode (STRONGKEYMODE) in the System Environment Settings.
If "1" (Enabled) is set, change it to "0" (Disabled).
