Convert SSL Certificate
Introduction
PFX certificates are used to store digital identities and encryption in a file format. Their conversion is necessary to ensure compatibility between different systems. Conversion to other formats such as PEM allows the certificates to be used in a wider range of applications.
Conversion to separate PEM files
Extract private key from a PFX file to a PEM file
openssl pkcs12 -in filename.pfx -nocerts -out key.pem
Remove the password from the extracted private key
openssl rsa -in key.pem -out server.key
Export the certificate
openssl pkcs12 -in filename.pfx -clcerts -nokeys -out server.pem
The intermediate must be included in server.pem, this can be easily checked and corrected on the following page https://whatsmychaincert.com/
