Generating the CRT key
Generate the CRT key used for encryption with the RSA (Rivest-Shamir-Adleman cryptosystem) public key encryption
method. CRT key is a type of the private key.
1
Click [Certificate] → [CRT Key generate] → [Execute].
The page to generate the CRT key is displayed.
2
Click [Execute].
When generating the CRT key for the first time, the following message is displayed after the CRT is generated.
Proceed to Step 4).
"CRT key - Generated"
When generating the CRT key for the second time or later, the following message is displayed.
"The CRT key will be generated. In updating the CRT key, the Server Certificate corresponds to the current CRT
key will become unavailable. Continue?"
3
Click [OK].
CRT key will be generated and the following message will be displayed.
"CRT key - Generated"
4
Click [OK].
Clicking [Certificate] → [CRT Key generate] → [Execute] again can confirm the key length and generation date and
time of the current CRT key with the [RSA key size] and [Last modified] of [Current CRT key] at the upper row of
the CRT key generation page.
Note
●
[Not generated] displayed in [Last modified] indicates that the CRT has not been generated.
●
[RSA key size] is fixed to [2048bit]. The server certificate may not be issued depending on the certification
organization to apply if the key length is 2048-bit.
●
Generation of the CRT key may take up to approximately two minutes.
●
When the CRT key is updated, apply for the server certificate or generate the self-signed certificate again using that
CRT key. A certificate linked to the CRT key is required.
●
Previously generated CRT key information is saved even if the CRT key is updated. To return to the previous CRT
key, refer to "Cancelling the update of the CRT key" (see page 106).
