Base32

Base32 is binary-to-text encoding based on the base-32 numeral system. It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (25). Since base32 is not very widely adopted, the question of notation i.e. which characters to use to represent the 32 digits is not as settled as in the case of more well-known numeral systems (such as hexadecimal) even though RFCs and unofficial and de facto standards exist. One way to represent Base32 numbers in human-readable form is using digits 0–9 followed by the twenty-two upper-case letters A–V. However, many other variat
