构建安全备份系统的技术指南

1. 建立安全的 HTTPS 连接

在与 Windows Azure 存储服务通信时，为确保数据传输的安全性，我们可以使用 HTTPS 连接。以下是一段 Python 代码示例，展示了如何创建一个安全的 HTTPS 连接：

# Create a connection object
if USE_HTTPS:
    ctx = SSL.Context()
    # Verify that the server chains to a known CA.
    # We hardcode cacerts.pem in the source directory
    # with GTE CyberTrust's certs which is what
    # Windows Azure chains to currently.
    ctx.set_verify(SSL.verify_peer | SSL.verify_fail_if_no_peer_cert, 9)
    # GTE's certs are kept in cacerts.pem in the same directory
    # as source. sys.path[0] always
    # contains the directory in which the source file exists
    if ctx.load_verify_locations(sys.path[0] + "/cacerts.pem")!=1:
        raise Exception("No CA certs")
