From Base45

Base45 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. The high number base results in shorter strings than with the decimal or hexadecimal system. Base45 is optimized for usage with QR codes. From Base45 lives in the Data format category of the fx menu. See Base45 for format details.
