WatchGuard Technologies SSL VPN APPENDIX C Installing Windows Certificates, To install Cygwin

APPENDIX C Installing Windows Certificates

The Firebox SSL VPN Gateway includes the Certificate Request Generator to automatically create a cer- tificate request. After the file is returned from the Certificate Authority, it can be uploaded to the Firebox SSL VPN Gateway. When the file is uploaded, it is converted automatically to the correct format for use. If you do not want to use the Certificate Request Generator to create the signed certificate, use Linux OpenSSL to administer any certificate tasks. If Linux is not available, Cygwin UNIX environment for Win- dows is recommended, which includes an OpenSSL module. Instructions for downloading, installing, and using the Cygwin UNIX environment to generate a CSR are included in this section.

If you are familiar with certificate manipulation, you can use other tools to create a PEM-formatted file. The certificate that you upload to the Firebox SSL VPN Gateway must have the following characteristics:

•It must be in PEM format and must include a private key

•The signed certificate and private key must be unencrypted

If Linux OpenSSL is not available, install the Cygwin UNIX environment for Windows. When you install Cygwin, you must choose the OpenSSL modules as described in the following steps.
