While installing the composer to user the laravel framework, I got some errors :
Download failed: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
file_get_contents(): Failed to enable crypto

The download failed repeatedly, aborting.
I'm sure that the Openssl in php.ini is enable.
回答1:
Having the OpenSSL extension enabled does not mean it is configured correctly.
It fails to validate the certificate for getcomposer.org. That means either some man-in-the-middle server messes with your request or you somehow did not configure the set of default CA Authorities. Your server operator can tell you more.

I have the same problem using wamp on windows 7, and I already enabled the openssl.dll in php.ini, still report the same error. my problem is caused by the network provider,and I have no idea what's wrong with the them. after I connect to a VPN network .it works like a charm.
