SSL converter – Use OpenSSL commands to convert your certificates to key, cer, pem, crt, pfx, der, p7b, p12, p7c, PKCS#12 and PKCS#7 format.
SSL converter helps you in solving the most common issues of certificate file-type during SSL/TLS certificate installation process. Sometimes trusted CA’s issues defined certificate which would not be compatible with your server as different servers require different types of file formats.
There are different file formats PEM, PFX, DER, P7B, PKCS#12, and PKCS#7 that can be measured by file extensions.
| File Types | Extensions |
|---|---|
| PEM | .key, .cer, .pem or .crt |
| PFX | .pfx |
| DER | .der or a .cer |
| P7B | .p7b |
| PKCS#12 | .p12 |
| PKCS#7 | .p7c |
OpenSSL Commands to Convert your SSL/TLS certificate
If your server doesn’t support Base64 encoded X.509 then you should convert your files as per your desired server using OpenSSL commands. You can easily convert your certificates into the right format by using following commands.
Convert PEM File
Convert PEM to DER
openssl x509 -outform der -in certificate.pem -out certificate.der
Convert PEM to P7B
openssl crl2pkcs7 -nocrl -certfile certificate.cer -out certificate.p7b -certfile CACert.cer
Convert PEM to PFX
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt
Convert DER File
Convert DER to PEM
openssl x509 -inform der -in certificate.cer -out certificate.pem
Convert P7B File
Convert P7B to PEM
openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer
Convert P7B to PFX
openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer
openssl pkcs12 -export -in certificate.cer -inkey privateKey.key -out certificate.pfx -certfile CACert.cer
Convert PFX File
Convert PFX to PEM
openssl pkcs12 -in certificate.pfx -out certificate.cer -nodes
