[Bug-wget] Mirroring a site

[Ryan Butler]

I'm trying to mirror a site and having a tough time with it because it's a
site that I have to login for school but doesn't use 'normal'
authentication.  I'm new to wget and I'm confused what I should do.  Every
attempt gives different errors but this one keeps coming up:
"Error:  cannot verify www.lib.byu.edu's certificate, issued by
'/C=US/O=DigitCert Inc/OU=www.digicert.com/CN=DigiCert Clobal CA':

Any help for a newbie??
