WebThe Baconian cipher uses a binary system of encoding the letters of the alphabet. For example, A is encoded with aaaaa, B is encoded with aaaab, and so on. This method encodes a true message in a seemingly innocuous note, where the first letters of the words in the message are converted into A or B depending on which half of the alphabet the ... WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm . This is known as breaking the cipher, ciphertext, or cryptosystem.
