WebCypher prescribes that, after the primary order of point in time, instant values be ordered by effective time zone offset, from west (negative offset from UTC) to east (positive offset … WebXOR encryption with a short pad (i.e., shorter than the plaintext) is basically the Vigenère cipher. So standard techniques to break Vigenère should break xor encryption.. The basic idea is that if the encryption key is d symbols long, every d-th symbol is encrypted with the same pad.Thus, take every d-th ciphertext symbol and treat it like simple substitution …
