Did You Know – Prime Numbers and Encryption

Yet another interesting thing I have learned from the Probably Science Podcast (I forget which episode this time).

Apparently, using prime numbers is the most effective form of computer encryption, because they are very very difficult to work backwards from. That is to say if you multiply 2 very large prime numbers together, the only real way to get back to where you started (unless you are incredibly patient and willing to sit there and do trial and error), is to know one (or both) of the original numbers.

Prime numbers for those who don’t know, are numbers that are only divisible by 1, and themselves. The number 1 is the first prime number, 3 is the second (it can’t be divided evenly in half), next is 7, and the largest one found to date is 257,885,161 − 1,[1] a number with 17,425,170 digits. That’s right, almost 17 and a half MILLION digits. Only divisible by 1, and itself. So you can imagine, if you multiply two 17.5 million digit numbers together, ain’t nobody but a computer ever gonna unmultiply em. You need to know the secret password (ie the prime number used).

One of my favourite indie films, “CUBE” (1997), [minor spoiler alert] also features a component of prime numbers as part of the plot. See also, the film “Pi” (1998).
