Large prime numbers are used in encryption. The larger the primes, the better the encryption. Typically each of two people will provide a prime; you need to know both prime numbers to decrypt.
A program is used to calculate the values to be sent. The message is sent along with the product of the primes (sender's prime * receiver's prime). Since the number will be large it is difficult to crack (again, larger the better). To decrypt you have to know both prime numbers. Knowing one and the product makes it easy (just divide). If you only have the product, decrypting can be very time-consuming as you are forced to find the factors of the number
