WebMay 20, 2011 · The reason is this: encryption algorithms work by producing what appears to be random data. If I encrypted two sentences each with two ciphers (four outputs), you would be unable to tell me with any confidence which ciphertext belonged to which cipher unless you decrypted it or broke the cipher. 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, …
