WebAug 19, 2016 · Let's say I have about a statistically good sample of characters of text that appear to be uniformly distributed, but the composition of the text is [A-Z], [a-z], [0-9], +, and / — constituting basically a base64 alphabet. To me, the more or less uniform distribution of the text suggests at least a polyalphabetic cipher, and possible a Vigenère. WebNov 23, 2015 · 6. That's a simple substitution cipher. Base 64 uses the following alphabet A-Za-z0-9+/. Here A encodes 000000, B encodes 000001 etc. In your case the g encodes 000000, P encodes 000001 etc. Instead of writing your own decoder for that you can simply take the ciphertext, iterate through the characters of the ciphertext and replace g with A, …
