If you were to be an onmyoji (an yin-yang exorcist), this gem would help your work. This gem provides the functions that encodes/decodes Base64 written in hexagrams, the figures used in I Ching. The API is compatible with the Base64 library in the Ruby Standard Library, so it is very easy to make your application more yin-yang-ful.
