Downloading Certificates in Binary Format

This download option will present you with a certificate that can be saved to a file in binary (ASN.1 or DER) format. By default, the filename will have a ".cer" suffix. Files containing certificates in this format can be imported into some PKI and S/MIME enabled applications.

If multiple certificates are returned for the specified email address, you will be prompted to select a certificate to save. Certificates selected from a multiple certificate list will be saved in a BASE64 encoded (PEM) format. These certificate files will also have a ".cer" suffix as the default filename. Typically, a certificate saved in BASE64/PEM format can also be imported into your application in the same way as the binary DER formatted certificates.
