export MC_HOST_foo=http://foo:foobar123@localhost:9000
mc ls foo
mc cp /etc/issue myminio/test/issue2
```

Only the last operation would fail with a permissions error.

## Configuration

Access Management Plugin can be configured with environment variables:

```sh
$ mc admin config set myminio policy_plugin --env
KEY:

  /** True if there was an exception on the connection to the peer. */
  internal var hasFailure: Boolean = false
    private set

  internal val connection: RealConnection
    get() = codec.carrier as? RealConnection ?: error("no connection for CONNECT tunnels")

  internal val isCoalescedConnection: Boolean
    get() = finder.routePlanner.address.url.host != codec.carrier.route.address.url.host

  @Throws(IOException::class)

////

这类似于：

```Python
if not (credentials.username == "stanleyjobson") or not (credentials.password == "swordfish"):
    # Return some error
    ...
```

但使用 `secrets.compare_digest()`，可以防御**时差攻击**，更加安全。

### 时差攻击

什么是**时差攻击**？

假设攻击者试图猜出用户名与密码。

他们发送用户名为 `johndoe`，密码为 `love123`  的请求。

然后，Python 代码执行如下操作：

# This should only be necessary when running on A GCP VM, on a default
# network, which has the MTU of 1460,
# due to 40 bytes being reserved for GCP's internal usage.
# Note, an invalid sub-interface name will lead to an obscure error, e.g.:
# "The filename, directory name, or volume label syntax is incorrect."
# In such cases, check that the name of the sub-interface is valid:
# `netsh interface show interface`

func getFormatStr(strLen int, padding int) string {
	formatStr := fmt.Sprintf("%ds", strLen+padding)
	return "%" + formatStr
}

// Prints the formatted startup message.
func printStartupMessage(apiEndpoints []string, err error) {
	banner := strings.Repeat("-", len(MinioBannerName))
	if globalIsDistErasure {
		logger.Startup(color.Bold(banner))
	}
	logger.Startup(color.Bold(MinioBannerName))
	if err != nil {
		if globalConsoleSys != nil {

            }

            bufferIndex += e.nextEntryOffset;
        }

        /* last nextEntryOffset for NT 4(but not 98) is 0 so we must
         * use dataCount or our accounting will report an error for NT :~(
         */

        //return bufferIndex - start;

        return dataCount;
    }
    public String toString() {
        String c;

        else
          echo "Ignoring --debug option as MAVEN_DEBUG_OPTS is already set"
        fi
        ;;
      --yjp)
        if [ ! -f "$YJPLIB" ]; then
          echo "Error: Unable to autodetect the YJP library location. Please set YJPLIB variable" >&2
          exit 1
