WebThe cipher is a general algorithm that is specified by the key. For example, substitution is a general algorithm that is specified by a key, which is the substitution for each letter. Rival groups can use the same substitution cipher, but they will choose different keys so that they can not read each other’s messages. The Enigma Cipher WebCiphers generated using the public key can only be decrypted by users holding the secret key, not by others holding the public key—however, the secret-key holder receives no information concerning the sender.
