can anyone tell me why my program makes the computer run (seemingly) forever on each individual character of a file, but happens practically instantly on other sites?
the program is called RSA
the main part of it is taking a character, turning it into a number and give it a large power, say 150 ^ (some 128 bit number). why does this calculation take so long on my computer, but can run instantly on everything from gmail to cellphones?
