Convert your SSL Certificate to the Correct File Type

To enable encryption on the site, different servers require different formats of SSL certificates. SSL converter changes 6 format files in an easy and fast way. Choose the one which is required: PEM, DER, PKCS#7, P7B, PKCS#12 or PFX.

DER formatIs a binary form of PEM. It has extension .der or .cer.

DER is typically used with Java platforms. Our Converter can change the type of certificate to this format - to change a private key, please use OpenSSL commands.

PKCS#7 or P7B formatIs usually stored in Base64 format and has extension .p7b or .p7c. Files in this format contain lines "-----BEGIN PKCS7-----" and "-----END PKCS7-----". This format is just for certificates, not for private keys.

PKCS#7 and P7B are installed on Microsoft Windows and Java Tomcat servers.

PKCS#12 or PFX formatIs a binary format storing the server certificate, intermediates certificates, and private key in one file. It usually has the extension .pfx or .p12. Typically, these are used on Windows machines.

When converting PFX format to PEM, one file will include all certificates and the private key.

To separate it, you need to open this file in a simple text editor, copy every single part (with BEGIN and END lines) to different files and save it as certificate.cer, CACert.cer and privatekey.key.
