Generating a CRT key (SSL encryption
key)
[CRT key generate]
●
A CRT key cannot be generated when self-signed
certificates and server certificates are enabled.
●
The size of the key that can be used by the Certificate
Authority (CA) differs when using a server certificate.
Confirm in advance the size of the key that can be
used.
●
Generating a CRT key takes about 1 minute for
1024 bit and about 2 minutes for 2048 bit. Do not
operate the web browser until CRT key generation is
complete. Image display and communication speed
may reduce while generating a CRT key.
Notes
1.
Click the [Execute] button in [CRT key generate].
The [CRT key generate] dialog is displayed.
2.
The size of the generated CRT key is selected
from [1024bit] / [2048bit] in [CRT key generate] –
[RSA key size].
●
When using a server certificate, the RSA key size
must be in accordance with the demands of the
Certificate Authority (CA) which will be applied to.
Note
3.
Click the [Execute] button.
CRT key generation starts.
When CRT key generation is complete, the size of the
CRT key generated by the [Current CRT key] and the date
and time generation concluded will be displayed.
●
Perform procedures 1 to 3 to change (update) the
generated CRT key. Because the CRT key, self-
signed certificate and server certificate are enabled
as a set, it will be necessary to once again generate
a self-signed certificate or apply for a server
certificate when the CRT key is changed.
●
When the CRT key is changed, previous CRT keys
are historically managed one at a time.
Clicking the [Apply] button in the [Current CRT
key] of the [CRT key generate] dialog displays the
[Previous CRT key] dialog, allowing confirmation of
the key size and the date and time generation was
completed.
Clicking the [Apply] button in [Previous CRT key]
allows the previous CRT key to be switched to the
current CRT key.
