enrollment challenge password about sscep

[bjanders]

I don't think this should be asked here, as it is not specific to sscep or an issue with sscep. Something like https://stackoverflow.com/ is better suited for general help requests like this.

If you are using OpenSSL, then you need to add challengePassword to your request, for example in openssl.conf:

[ req_attributes ]
challengePassword=4CF4C5D57E1E3B68

You can use the sscep mkrequest script to do this for you, or you can use that as an example for your own script.
