in USG FLEX H Series

Hello everyone,

I try to use the internal certificate functionality; I've tried to create a cert and download it, all works.

But, when I try to export the CA certificate from the "Trusted Certificates" tab, the downloaded file seems to be corrupted.

Anyone that uses this functionality? Can you help me to export the CA cert?

Thank you

    Hi @Maverick87

    It's about the certificate file format.

    PEM format: Text-based (Base64 encoded)

    DER format: Binary

    Zyxel firewall exported format is DER.

    You need using tool to convert the format. (e.g. openssl or some online convert, https://certificatetool.com/ssl-converter/der/der-to-pem)

    Hi @zyman2008,
    OK but ….

    Seems that the default name have ".CRT" into the file name; also the saving window show me only ".CRT" or "*.*" as filter.

    So, ok can be a DER file, but if not specified we cannot say it.

    @Zyxel_Melen could you checking for this?

    Thank you
