File in Binary DER Format
This option lets you save a CRL in raw binary format to a file displayed in the filename field. By default, the file is saved or exported with a .DER extention at the root of drive C: of the workstation.
File in Base64 Format
This option lets you save a CRL in Base64-encoded ASCII format to a file displayed in the filename field. By default, the file is saved or exported with a .B64 extention at the root of drive C: of the workstation. This option is recommended if you need to send the file using obsolete e-mail programs that cannot handle raw binary attachment files.
