1b) Receive decrypted data key.
2)  Decrypt encrypted object key with the KEK derived from the data key.

3b) Receive encrypted form of the data key from the KMS.
4)  Derive a new KEK from the new data key and re-encrypt the OEK with it.

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

The process to acquire one of these certificates used to be cumbersome, require quite some paperwork and the certificates were quite expensive.

But then **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** was created.

        final int tagLength = getAuthTagLength();
        final byte[] ciphertext = new byte[encrypted.length - tagLength];
        final byte[] authTag = new byte[tagLength];

        // Use constant-time copy operations
        constantTimeCopy(encrypted, 0, ciphertext, 0, ciphertext.length);
        constantTimeCopy(encrypted, ciphertext.length, authTag, 0, tagLength);

        return new EncryptionResult(ciphertext, authTag);

func TestIsEncrypted(t *testing.T) {
	for i, test := range isEncryptedTests {
		if _, isEncrypted := IsEncrypted(test.Metadata); isEncrypted != test.Encrypted {
			t.Errorf("Test %d: got '%v' - want '%v'", i, isEncrypted, test.Encrypted)
		}
	}
}

var s3IsEncryptedTests = []struct {
	Metadata  map[string]string
	Encrypted bool
}{
	{Encrypted: false, Metadata: map[string]string{MetaMultipart: ""}},                             // 0

        byte[] encrypted = cipher.doFinal(plaintext);

        cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);
        byte[] decrypted = cipher.doFinal(encrypted);

        // Then
        assertNotNull(encrypted);
        assertNotNull(decrypted);
        assertArrayEquals(plaintext, decrypted);
        assertNotEquals(new String(plaintext), new String(encrypted));
    }

}
```

Optionally `--encrypt` can be specified. This will output an encrypted file and a decryption key:
