+The `encoding` API implements a few useful functions to handle various types of encoding.
+
+### encoding.base64Encode(data)
+Encodes data (either a string or byte buffer) as a base64 encoded string.
+
+### encoding.base64Decode(s)
+Decodes a base64 encoded string into a byte buffer.
+
+### encoding.utf8Encode(s)
+Encodes a (UTF-8) string into a byte buffer.
+
+### encoding.utf8Decode(data)
+Decodes a byte buffer into a (UTF-8) string.
