Webb1 jan. 2024 · For example using the acii table to convert values into ciphertext: Converting "NO" into a cipher where m = 7879 N = 373097 and e = 459173 effectively the algorithm then becomes: ( 7879) 459173 M o d 373097 It seems inconceivable to even attempt to utilize successive squaring with an exponent of 459173.
