I am new in blockchain development. I just start a sample hyperledger project. The default expired period of certificates is 10 years. Have any solutions or ways are available to increase the certificate validity. I actually need to change it to 20 years. Please give any way to do it.
Fabric:1.1.0
Composer:0.19.16
OS:Ubuntu 16.04
I just suggest to use Openssl for generate the self signed certificate.
eg:
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365
//change day as you want. Hope it helpful.
