working

• What actually happened instead?

[Composer\Downloader\TransportException]
The "https://xxx/repository/composer-public/packages.json" file could not be downloaded: SSL operatio
n failed with code 1. OpenSSL Error messages:

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

something maybe help:

1. i choose native Windows Secure Channel Library as Https transport backend
2. the company CA file, xxx.crt can work normally in chrome, it seems like git windows can not get the windows certificate store
