What is the most efficient way to encode an arbitrary GUID into readable ASCII (33-127)?

Question

The standard string representation of GUID takes about 36 characters. Which is very nice, but also really wasteful. I am wondering, how to encode it in the shortest possible

Answer 1

An arbitrary GUID? The "naive" algorithm will produce optimal results. The only way to compress a GUID further is to make use of patterns in the data excluded by your "arbitrary" constraint.
