# MinIO STS Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

The MinIO Security Token Service (STS) is an endpoint service that enables clients to request temporary credentials for MinIO resources. Temporary credentials work almost identically to default admin credentials, with some differences:

	data = bytes.TrimSpace(data)

	// Parse all certs in the chain.
	current := data
	for len(current) > 0 {
		var pemBlock *pem.Block
		if pemBlock, current = pem.Decode(current); pemBlock == nil {
			return nil, ErrTLSUnexpectedData(nil).Msgf("Could not read PEM block from file %s", certFile)
		}

		var x509Cert *x509.Certificate
		if x509Cert, err = x509.ParseCertificate(pemBlock.Bytes); err != nil {

            return complete + " B ";
        }
    }

    private void pad(StringBuilder buffer, int spaces) {
        String block = "                                        ";
        while (spaces > 0) {
            int n = Math.min(spaces, block.length());
            buffer.append(block, 0, n);
            spaces -= n;
        }
    }

    @Override
    public void transferSucceeded(TransferEvent event) {

      assertEquals("jpeg", mediaType.subtype)
    }
  }

  private fun <T> withLocale(
    locale: Locale,
    block: () -> T,
  ): T {
    val previous = Locale.getDefault()
    try {
      Locale.setDefault(locale)
      return block()
    } finally {
      Locale.setDefault(previous)
    }
  }

  @Test fun testIllegalCharsetName() {

		t.Errorf("Update a filed with a default value should occur. But got %v\n", animal.Name)
	}

	// When changing a field with a default value with blank value
	animal.Name = ""
	DB.Save(&animal)
	DB.First(&animal, animal.Counter)
	if animal.Name != "" {
		t.Errorf("Update a filed to blank with a default value should occur. But got %v\n", animal.Name)
	}

# MinIO Server Debugging Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) [![Docker Pulls](https://img.shields.io/docker/pulls/minio/minio.svg?maxAge=604800)](https://hub.docker.com/r/minio/minio/)

## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://docs.min.io/community/minio-object-store/reference/minio-mc-admin/mc-admin-trace.html) command.

Example:

```sh
minio server /data
```

    byte[] key = fillByteArray(80, 0xaa);
    String data = "Test Using Larger Than Block-Size Key - Hash Key First";

    checkSha1("aa4ae5e15272d00e95705637ce8a3b55ed402112", key, data);
  }

  public void testRfc2202_hmacSha1_case7() {
    byte[] key = fillByteArray(80, 0xaa);
    String data = "Test Using Larger Than Block-Size Key and Larger Than One Block-Size Data";

		t.Fatalf("Transaction return error will equal the block returns error")
	}

	if err := DB.First(&User{}, "name = ?", "transaction-block").Error; err == nil {
		t.Fatalf("Should not find record after rollback")
	}

	// commit
	DB.Transaction(func(tx *gorm.DB) error {
		user := *GetUser("transaction-block-2", Config{})
		if err := tx.Save(&user).Error; err != nil {

And in many cases, reading them would be a blocking operation (that could block the event loop), because they are read from disk or from the network.

/// info

The example above is actually an exception, because the `io.BytesIO` object is already in memory, so reading it won't block anything.

But in many cases reading a file or a file-like object would block.

# KMS Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO uses a key-management-system (KMS) to support SSE-S3. If a client requests SSE-S3, or auto-encryption is enabled, the MinIO server encrypts each object with a unique object key which is protected by a master key managed by the KMS.
