Creating a PKCS#12

Hi everyone, I used Certbot on a Centos 8 server to create and install a Lets Encrypt certificate on one of the sites hosted on that server, there are 5 sites, one site uses a certificate from another provider while the other 4 they use Lets Encrypt, so far coexistence is OK.
Now I would like to use my UTM to add an extra layer of security by configuring reverse proxy but it asks me to load PKCS # 12.
How can I generate this file considering that the certificate was generated with Certbot?

The version of my client is certbot 1.10.1

Many thanks in advance.

Hi @papalii, and welcome to the LE community forum :slight_smile:

The fullchain.pem and privkey.pem files created by certbot can be converted to PKCS#12 format.
OpenSSL is one software that can be used to do that quite easily, with:
openssl pkcs12 -export -in fullchain.pem -inkey privkey.pem -out domain.pfx


It works! it was very simple, thank thanks you very much!


Glad to help :slight_smile:
Cheers from Miami :beers:
