+#Takes a string as an argument and returns 3 base64 encoded string partials.
+#One of these strings is guaranteed to be present in the base64 content if
+#the original plain-text code contained the (case-sensitive) input string.
+
+#Due to the 8 bit to 6 bit encoding conversion involved in base64 encoding,
+#the edges don't always align nicely, so trimming is required as the first
+#and last characters may be different depending on the immediate context.
