my network does not work well with https, so doing

composer.phar install

throws

  [ComposerDownloaderTransportException]                                                         
  The "https://packagist.org/packages.json" file could not be downloaded: Failed to enable crypto  
  failed to open stream: operation failed  

i used

{
    "packagist": false
},
{
    "type": "composer",
    "url": "http://packagist.org",
    "options": {
        "ssl": {
            "verify_peer": "false"
        }
    }
}

as a http falback, but again it crashes in some other point:

my problem is just with TLSv1, previous SSL versions should work, as the browsers work correctly.

how should i do, the problem also exists in other cmd tools that depend on https like npm, bower, git, curl, ...

composer config --global disable-tls true
composer config --global secure-http false
