Hello @mr-tz I started working on this issue.

I have currently changed for stack_strings , that if a String is base_64 , it is identified . I have attached the output .

Kindly see through it and suggest the changes necessary .

The intent of this issue is to track the idea that the "decoding routine identification phase" should take into account references to the Base64 alphabet. The intuition being that when the Base64 alphabet is seen, it's probably used nearby to decide some data. So in the same part of the code where we recognize non-zero xor and high xrefs, we should also inspect string references for the default Base64 alphabet.
