SSL Converter
Convert your SSL certificate to different formats
If your CA has sent you the certificate file in a format that your server doesn't accept, you'll need to convert the certificate file's format . You can easily do this on your own system by running a few OpenSSL commands . Down below, we have compiled OpenSSL commands that you'll need based on your certificate format and server type.
OpenSSL commands to convert PEM file
- Convert PEM to DER
- Convert PEM to P7B
- Convert PEM to PFX
openssl x509 -outform der -in certificate.pem -out certificate.der
openssl crl2pkcs7 -nocrl -certfile certificate.cer -out certificate.p7b -certfile CACert.cer
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt
OpenSSL commands to convert DER file
- Convert DER to PEM
openssl x509 -inform der -in certificate.cer -out certificate.pem
OpenSSL commands to convert P7B file
