I have generated a free SSL from
zerossl.com through their wizard, and finally I got a pure text file containing pure text with two
I want to know how to generate
key from that file/text.
I have three text files:
Here's the guide from the site:
Your certificate is ready! Congratulations on receiving your Free SSL Certificate. Please note that certificates are valid for 90 days, but they are free to renew. To renew just repeat the process, using the same LE key and CSR as you used last time. Using the same CSR means that you do not need a new domain key (it will stay the same) and will only need to update the certificate file on your server. Keep your keys and CSR safe. Make sure you remember where you saved your generated account key!
Your account ID is 48546566 - please write it down somewhere. You will not normally need this, but together with email it might help you to restore your account quicker if you lose your account key.
When installing the certificate, keep in mind that it should be used with the domain key, NOT the LE key from the "Details" screen. The LE key should be only used on the "Details" screen when issuing or renewing your certificate. On renewal that will allow you to skip the verification of already verified domains. Your certificate file contains both your domain certificate and the issuer's certificate. Most modern web servers will accept them as is. However, old versions of Apache, Amazon Web Services (AWS) and some control panels would want them separately. In that case just split the certificate file in two, preserving BEGIN and END lines around both certificates. The first one is your domain certificate, the second one is the issuer's, which in control panel interface may be called "Intermediate certificate", "Certificate chain" or "CA Bundle".
