WebThe Porta Cipher is a polyalphabetic substitution cipher invented by Giovanni Battista della Porta. Where the Vigenère cipher is a polyalphabetic cipher with 26 alphabets, the Porta is basically the same except it only uses 13 alphabets. The 13 cipher alphabets it uses are reciprocal, so enciphering is the same as deciphering.

WebMany cipher algorithms increase their protection by increasing the size of the keys they use. However, the larger the key, the more computing time is needed to encrypt and decrypt data.
