matlab task RSA

Be written in MATLAB code for encrypting text (random number of characters) by using the RSA encryption algorithm. Also be achieved the decryption format. To assume that the characters that can be used in the text are the 26 capital letters of the English alphabet and the gap (total of 27 characters). Examples of text are shown below (for ease of reading, the gaps they have been replaced by "_"): - “HANNIBAL_ANTE_PORTAS_ROMA“ - “MEETING_IN_LONDON” Encryption with RSA algorithm requires the original message (plaintext) is a number (this number must be less than the modulus system). In order be used for the algorithm's parameters (p, q, n, e and d, in accordance with the description of the RSA in notes of course) relatively small numbers, characters the plaintext to be divided into groups of 3 characters and in every group be attributed Encryption with RSA algorithm requires the original message (plaintext) is a If the last group does not have 3 characters to be filled with blank characters). Then this number will be encrypted with the RSA algorithm and the number who will occur will be the ciphertext. The total encrypted text is sequence of numbers generated by the separate encryptions. For the encoding of characters in numbers attributed to each character a number (e.g. Empty = 0, a = 1, b = 2, ... Z = 26) and found an imaging mode groups of 3 characters in unique number. Example imaging method is to consider that These characters are digits of 27-your own numbering scheme in which now the radix is 27. Examples of such Imaging groups of 3: Trilogue of characters Number . Number "___" (3 empty) 0 "_AB" 29 "Z_Z" 18980 Based on the above illustration (or some other that you want, as long as it's 1 to 1) to select appropriate values for the parameters of the RSA algorithm and show encryption/decryption results for the above 2 posts will occur will be the ciphertext. The total encrypted text is
