@acer  Thanks for your response i knew to do the &^ but i didnt know about the other parts, is it possible that you can also show me how this can be extended to encrypt messages?

@acer the specific message I want to decrypt Is a full maple document full of 11 digs long each cipher block the response you posted doesn't seem like a procedure it just seems like the protocol which I already know it isn't a problem for me to decrept this message using a pen and paper  I don't understand why I need to generate a random number so that condition holds when I need to decrypt it and not encrypt it could you go into further detail about this? Also my procedure runs it just doesn't seem to give any output and it's been very stressful looking at it recently 

@acer i specifically want the smallest solution and i dont want to use an inbuilt function i would like to know how to write a procedure to calculate x, thanks

@acer here is my attempt as of now

rsa(26271227347, 11393739244);
                 rsa(26271227347, 11393739244)

here n is 26271227347 and the ciphertext in ascii is 11393739244 it runs but doesnt give anything back
sorry i didnt know how to format it to show as a code

i want the smallest possible solution and i know about the inbuild function i was looking for the actual procedure though

the following was from a book i'm trying to learn from but the book dosent include a solution 

is that just using a normal alpha numeric replacement method? or is that using ascii also?

@acer hi thanks for the prompt response, and no i'm not hoping for a secure padding scheme this is just merly for me to decrypt and encrypt messages i'm sending to a friend to comunicate. no this is not coursework i havent had the luxury of studying a cryptologoy course otherwise i might have been able to figure it out :)

@acer  not really but that's useful to know I'm trying to figure out how I can write a complete procedure that when given a message X encrypted with rsa using public key (n,e) n not too large can decrypt X where maple is using ascii for the conversion of the message
