Base64 is an encoding scheme that is commonly used for data transport; it is not considered encryption because it has a known method for decoding, and does not require a unique key to decode the data. Base64 contains ASCII-printable characters, but the underlying data is binary (which will make our output somewhat messy!). An example from the payload column in the messages table of tc.db looks like this:
