SSL Converter

SSL certificates are typically issued in one of several different file formats, including DER, PEM, PKCS#7, P7B, PKCS#12, and PFX. These formats are used to store the certificate and any associated private keys or intermediate certificates.

To use an SSL certificate on a server, it is typically necessary to convert it to a format that is compatible with the server. This can be done using a variety of tools, depending on the specific file format and the operating system being used.

Use our SSL Converter tool to convert SSL certificates to and from different formats such as PEM, DER, PKCS#7, P7B, PKCS#12 and PFX. To convert an SSL certificate from one format to another, select the certificate file and its current format, select the target format, and then click “Convert Certificate.” If the certificate has a private key, you may also need to provide a password.

Your private key is intended to remain on the server. While we try to make this process as secure as possible by using SSL to encrypt the key when it is sent to the server, for complete security, we recommend that you manually convert the certificate on your server using the OpenSSL commands below.
