When you need a higher level of security for your messages or your data as you send it across the web, you should consider using public key cryptography to keep your messages safe from prying eyes. With this type of encryption two separate and very distinct keys are used. The first one is called the public key and is used to encrypt the message. The other one is the private key and is used to decrypt the message when it reaches the other end.
There are other uses for this type of encryption system such the pay now button on many different online retail sites. Here the public key is the one used on the website to protect the buyer's information when they enter it to pay their bill and the private key is used by the seller to decrypt the information so that they can get paid by the buyer's bank.
