+5. Implementing Stronger Security
+
+The default encryption/decryption logic in this example is intended for demonstration purposes only.
+
+If you require a higher level of security, it is recommended to implement your own encryption, decryption, authentication, and checksum algorithms by customizing the security callbacks in the BluFi framework.
