Generating p12 certificate using openSSL

 

                    

  This blog explains the steps needed to create .p12 certificate using openSSL command. There can be other ways of generating the certificate

.

Step 1: The first step as part of creating .p12 certificate is to generate a private key and public certificate using openssl.

openssl req -newkey rsa:2048 -nodes -keyout dev_key.pem -x509 -days 365 -out dev_certificate.pem

            

Step 2: On executing the above command, provide your response to the questions.

             

Step 3: On creation of the public certificate and private key,now its time to review the certificate 

using the below command.

openssl x509 -text -noout -in dev_certificate.pem

               

Step 4: The next step is to combine the private key and public certificate in PKCS#12 (P12) bundle using the below command. I have used the password as "password" in this case.

openssl pkcs12 -inkey dev_key.pem -in dev_certificate.pem -export -out dev_certificate.p12

               

Step 5: Finally validate your P12 file.

openssl pkcs12 -export -out dev_certificate.p12 -inkey dev_key.pem -in dev_certificate.pem

              

Step 6: Verify the folder to see if the .p12 certificate got generated or not.
