Creating a certificate and private key
Create sha1/sha256 and 1024bits/2048bits certificate and private key for the PDU..
Prerequisites
The PDU needs the following environments to create a certificate and private key.
• Operating system—Linux
• Apps—OpenSSL
Procedure
1. Open Terminal on your Linux operating system.
2. Enter mkdir cer.
3. Enter cd cer.
4. Enter openssl req -x509 -$1 - newkey rsa :$ 2 - keyout cert.key -out cert.crt -
days $3 -nodes.
NOTE: You can generate different types of certificates and private keys based on different $1, $2 and $3.
To generate the different certificate and private keys, replace $1, $2 and $3 with the following options:
• $1—sha1 or sha256
• $2—1024 or 2048
• $3—valid period of certificate
For example, openssl req -x509 -sha256 - newkey rsa:2048 - keyout cert.key -out
cert.crt -days 1024 -nodes. In this case, we are trying to generate sha256/2048bits certificate
and private key that can be valid for 1,024 days.
5. To enter the following information, follow the instructions.
• Country name
• State
• Locality name
• Organization name
• Organizational unit name
• Common name
• Email address
6. Navigate to the cer folder and obtain the cert.crt and cert.key.
7. Login to the PDU with the GUI>Network Setting>Web/ RESTapi Access Configuration.
8. Make sure that the access is set to web access>Https and web port> 443, RESTapi Access>enable.
9. Click the Set Certificate Key icon, and then choose SSL Certificate Key Length (1024/2048) bits.
10. Upload the cert.crt and cert.key.
