WebMorse code translator: Encode and convert online. Morse code, named for the inventor of the telegraph Samuel F. B. Morse, is a method of transmitting text information as a series of on-off tones, lights, or clicks. The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed. Its primary merit is that it is … See more In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: A $${\displaystyle \oplus }$$ 0 = A, A For example where See more Example using the Python programming language. See more The primary reason XOR is so useful in cryptography is because it is "perfectly balanced"; for a given plaintext input 0 or 1, the ciphertext result is equally likely to be either 0 or 1 for a truly random key bit. The table below shows all four possible pairs of plaintext … See more • Block cipher • Vernam cipher • Vigenère cipher See more
