Generating Certificates with OpenSSL

WestOderman

1 In OpenSSL, generate a private key using the following command:

openssl genrsa 2048 > private.pem

2 Generate the self-signed certificate using the following command:

openssl req -x509 -days 1000 -new -key private.pem -out public.pem

3 Create the PFX using the following command:

openSSL pkcs12 -export -in public.pem -inkey private.pem -out mycert.pfx

Creating PKCS#12

To create a PKCS#12 file with the self-signed certificate and private key, use the following command:

openssl pkcs12 –export –out mycert.pfx –inkey key.pem –in mycert.pem
