Hi curlers,

I got an error log, when I used the curl command in my embedded linux
device.
My curl is cross compiled with arm-none-linux-gnueabi.
The command and log as below:
/tmp # ./curl -v --cacert /tmp/cacert.pem https://curl.haxx.se/
* Trying 80.67.6.50...
* TCP_NODELAY set
* Connected to curl.haxx.se (80.67.6.50) port 443 (#0)

More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

I want to visit the https website.
I don't know if the format of the cacert.pem is right. :-(
Can someone help me?
