Base36 id strings

This set of functions exists to convert various data types to and from base36 strings.

Why a base36 string?

• Base36 strings are great way to shorten numeric ids for external applications. For example: 1000000 (1 million) converts down to LFLS.
• Base36 strings are alphanumeric, using only commonly used letters and numbers
• Base36 strings are case-insensitive

Where have I seen this before?

• Microsoft product keys
• Various HR software
