We will perform maintenance on the J-UPKI system on the following date.
Date: Wednesday, August 4, 2021, 10:00-10:30
Impact: The J-UPKI system will not be available during the above time period.
Description: Change the expiration date of the client certificate
---
The expiration date of the client certificate will be changed after the maintenance.
The expiration date of the client certificate is as follows.
- Certificates issued prior to maintenance.... 52 months
- Certificates issued after maintenance... 25 months
The digital certificate issued before the maintenance will still be available as a certificate with a validity of 52 months.
If you want to use a certificate with an expiration date of 25 months, please revoke the certificate after the maintenance and reissue it again.
*If you use only a client certificate as an authentication factor, authentication to use SSL-VPN fails when the certificate is revoked. If you are off-campus, please set up a one-time password (OTP) and revoke it.
*If you are using a wireless LAN (SSID: JAIST/eduroam), please change the referenced digital certificate to the newly issued one.
Certificates that have been applied for issuance and not downloaded before 10:00 a.m. on August 4 will be cancelled. Please apply for issuance again.
