gencert -h

Usage of ./gencert:
  -cert string
        Certificate file (default "certfile.crt")
  -days int
        Duration that certificate is valid for, in days (default 365)
  -hosts string
        Comma-separated hostnames and IPs to generate a certificate for (default "localhost")
  -key string
        Private key file (default "keyfile.key")
  -org string
        Organization name (default "Yo Medical Files(U) Ltd")
  -p12
        Convert certificate and key to PKCS#12 format
  -p12file string
        PKCS#12 file (default "certfile.p12")
  -root-ca string
        Root CA certificate file (default "rootCA.crt")
  -root-ca-key string
        Root CA private key file (default "rootCA.key")

Gencert generates a self-signed certificate for the given hostnames and IPs.

gencert -hosts "localhost,192.168.1.43" -org "Yo Medical Files(U) Ltd"

This will generate a certificate and key file for the given hostnames and IPs. It will also generate a root CA certificate and key file.

You must install the root CA certificate in your browser and/or system to trust the generated certificate.

Convert .crt to .p12

openssl pkcs12 -export -out certificate.p12 -inkey keyfile.key -in certfile.crt

Or use gencert to generate a .p12 file.

gencert -hosts "localhost,192.168.43.222" -org "Yo Medical Files(U) Ltd" -cert "certfile.crt" -key "keyfile.key" -root-ca "rootCA.crt" -root-ca-key "rootCA.key"

This will generate .crt and .key files for the given hostnames and IPs. It will also generate a root CA certificate and key file. Now you can convert the .crt and .key files to .p12 file.

gencert -p12 -p12file "certificate.p12" -cert "certfile.crt" -key "keyfile.key"
