It looks for it in the current folder. You can also call it from a
different folder specifying the full path.
But note that it is reading it here, the error is "PEM
routines:PEM_read_bio:no start line", otherwise it
would be "system library:fopen:No such file or directory"

You shouldn't need sudo here, just for running it on this folder (it
wouldn't be able to save it there, but you could use for instance -O
It's strange it worked for you, as I wasn't able to get it work using

Note that the wget manual also says "the file name is based on a hash
value derived from the certificate. This is achieved by
processing a certificate directory with the `c_rehash' utility supplied
In this case, running c_rehash <folder>, creates a symlink from
3cc93452.0 to forums.mvgroup.org.pem
Using wget with ca-directory does work for me if there is such link, but
I suppose wget is also trying to open it at
/System/Library/OpenSSL/certs/3cc93452.0, so if you make such symlink
there it should also work.
