LiquidFiles Documentation

The LiquidFiles appliance uses PEM format for it's certificate. If your CA is asking for a server type you can specify either Nginx, Apache or PEM as the format.

If your certificate is in another format, the easiest is probably to search the web for something like: Certificate DER to PEM, and you will find several options where you can convert the certificate. The certificate is public so there's no harm doing this on public websites.

If your certificate is in PFX/PKCS12 format (that is one file that includes both the certificate and the private key), please go to Admin → Certificate, and click on "Upload PFX/pkcs12" to upload and install the certificate and key into LiquidFiles.

The rest of these examples use the OpenSSL command line program to convert certificates to PEM format.

Please note that you don't have to run these OpenSSL commands on the LiquidFiles system. If you're more comfortable with Windows, run it on Windows. OpenSSL Windows binaries are available here: http://www.openssl.org/related/binaries.html.

Convert DER to PEM

openssl x509 -inform der -in certificate.cer -out certificate.pem

Convert P7B to PEM

openssl pkcs7 -print_certs -in certificate.p7b -out certificate.pem

When completed, please continue to the Certificate Installation guide..
