Convert pfx file to pem file
Conversion to a combined PEM file
To convert a PFX file to a PEM file that contains both the certificate and private key, the following command needs to be used:# openssl pkcs12 -in filename.pfx -out cert.pem -nodes
Conversion to separate PEM files
We can extract the private key form a PFX to a PEM file with this command:# openssl pkcs12 -in filename.pfx -nocerts -out key.pem
Exporting the certificate only:# openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
Removing the password from the extracted private key:# openssl rsa -in key.pem -out server.key
