About SSL Converter

SSL Converter

SSL Converter lets you convert SSL certificates in different formats: pem, der, p7b, and pfx. These certificate formats are needed for various platforms and devices. For example, Windows servers require a .pfx file and the Apache server require PEM (.crt, .cer) files.

How to use an SSL converter?

To use an SSL converter, choose the certificate file and its type (the type is automatically chosen based on the file extension). Then, you will have to pick the type of certificate for conversion. To do this, click on the button "Convert."

PEM format

PEM format is one of the most used and popular formats of certificate files. Usually PEM-files have the extension .pem, .crt, .cer, and .key. They are Base64-encrypted ASCII files and contain the lines "----- BEGIN CERTIFICATE -----" and "----- END CERTIFICATE -----". PEM format can store server certificates, intermediate certificates, and private keys. Different servers, including Apache and others, use PEM format certificates. In some cases, the PEM certificate and private key can be combined into a single file, but for most platforms certificate and private key must be separated.

DER format

DER format - a binary form of a certificate. Files in this format can have the extension .der or .cer. The only difference between them is the BEGIN/END lines. Any type of certificate and private keys can be represented in DER format. Commonly, this format is used with the Java platform. With an SSL converter, you can convert SSL certificates in DER format.

PKCS # 7 / P7B

The PKCS # 7 or P7B format is Base64 ASCII-file with the extension .p7b or .p7c. P7B certificates contain the string "----- BEGIN PKCS7 -----" and "----- END PKCS7 -----". Files of these certificates do not include the private key. The P7B files include only the certificates and certificate chains. P7B format is supported by platforms such as Microsoft Windows 10 &Java Tomcat.

PKCS # 12 / PFX

PKCS # 12 or PFX - a binary format used to store intermediate certificates, server certificates, and private keys in a single file. Extensions of PFX-file - .pfx and .p12. Most of these files are utilized on Windows devices to import and export private keys and certificates. After converting PFX to PEM, you will need to open the resulting file in a text editor and save each certificate and private key to a text file - for example, cert.cer, CA_Cert.cer, and private. key. You should copy the required snippets jointly with BEGIN / END.
