How To Import SSL Certificates To Your LoadMaster

To import an SSL certificate to the LoadMaster, navigate to Certificates & Security > SSL Certificates > Import Certificate.

The two formats officially supported by the LoadMaster are .PEM and .PFX. However, other formats can also be imported to the LoadMaster. This article covers the .PEM, .PFX. and .CER certificate formats and the variations in which they can be added to the LoadMaster.

PFX (PKCS#12) Certificate Format

PFX or PKCS#12 format is a binary format for storing a server certificate, intermediate certificates, and the private key all in one encrypted file. PFX files can have the extensions .pfx and .p12. If the PFX format contains the private key, the key file does not have to be imported.

To import a PFX format certificate containing a private key, add the .pfx or .p12 certificate file, the pass phrase configured when creating the PFX certificate file, and the Certificate Identifier which is the name that used to identify the certificate on the LoadMaster.

PEM (X.509v3) Certificate Format

The PEM extension is used for different types of X.509v3 files which contain ASCII (Base64) armored data prefixed with a “—– BEGIN …” line. The .PEM certificate format that may include just the public certificate, or may include an entire certificate chain including public key, private key, and root certificates. If the .PEM certificate contains the private key within it, you will need to add the Certificate File, Pass Phrase, and Certificate Identifier and click Save.

CER (X.509) Certificate Format

CER file is used to store X.509 certificate. The file contains information about certificate owner and public and private certificate keys. A CER file can be in binary (ASN.1 DER) or encoded with Base-64 with header and footer included (PEM). Windows recognizes either of these layouts. Though the .CER certificate file contains information about the private key, it does not contain the private key file and should be included when importing the .CER certificate file to the LoadMaster. To import a .CER certificate file, add the Certificate File, the Key File, and the Certificate Identifier.
