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. WebBase64 isn't really a cipher, since there is no key.

In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in sequences of 24 bits that can be represented by four 6-bit Base64 digits. Common to all binary-to-text encoding schemes, Base64 is designed to carry data stored in binary formats across channels that only reliably support text content.

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.
