## 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 **[Let's Encrypt](https://letsencrypt.org/)** was created.

        // Encrypt
        byte[] encrypted = storage.encryptCredentials(plaintext);
        assertNotNull(encrypted, "Encrypted data should not be null");
        assertTrue(encrypted.length > 0, "Encrypted data should have content");

        // Verify plaintext is not in encrypted data
        String encryptedStr = new String(encrypted);

        this.secureRandom.nextBytes(nonce);
        return nonce;
    }

    /**
     * Encrypt an SMB2 message with constant-time operations
     *
     * @param message
     *            plaintext message to encrypt
     * @param sessionId
     *            session identifier
     * @return encrypted message with transform header
     * @throws CIFSException
     *             if encryption fails
     */

### Using `mc encrypt` (recommended)

MinIO automatically encrypts all objects on buckets if KMS is successfully configured and bucket encryption configuration is enabled for each bucket as shown below:

```
mc encrypt set sse-s3 myminio/bucket/
```

Verify if MinIO has `sse-s3` enabled

```
mc encrypt info myminio/bucket/
Auto encryption 'sse-s3' is enabled

	plaintext, err := Decrypt(k, bytes.NewReader(ciphertext), context)
	if err != nil {
		return nil, err
	}
	return io.ReadAll(plaintext)
}

// Encrypt encrypts the plaintext with a key managed by KMS.
// The context is bound to the returned ciphertext.
//
// The same context must be provided when decrypting the
// ciphertext.
