Here’s how to convert SSL certificate from PFX to PEM format.
#!/bin/bash echo "This script converts SSL certificates from PFX to PEM." read -p 'Enter PFX Certificate Name : ' cert_pfx read -p 'Enter the Import Passphrase : ' import_passphrase openssl pkcs12 -in $cert_pfx -nocerts -out cert-key.pem -passin pass:$import_passphrase -passout pass:$import_passphrase openssl pkcs12 -in $cert_pfx -clcerts -nokeys -out cert-body.pem -passin pass:$import_passphrase -passout pass:$import_passphrase openssl pkcs12 -in $cert_pfx -nodes -nokeys -out cert-chain.pem -passin pass:$import_passphrase -passout pass:$import_passphrase sleep 3 openssl rsa -in key.pem -out cert-private.key -passin pass:$import_passphrase -passout pass:$import_passphrase |
