hi.

i was wondering which place is best for my question and i found this. if its wrong move it.

 

i know basics of rsa cryptography but it works on numbers and not not on texts. does it use ascii code to encrypte words letter by letter? can you give me a good explanation and example? so the changing place of words and letters will not happen? i want to know is it possible to encrypte signals like voices and pictures by RSA? thank you for helping

If you really want to know how to encrypt large data like an audio clip, get the book called Applied Cryptography 20th Anniversary Edition.

 

In the book, it gives an example how to break up the message (the data converted to an integer) into tiny pieces (3 digits each) and encrypt the lot of them. Of course, larger pieces can be used so long as each piece is less than p*q, where p and q are large prime numbers.
