A few months back I wrote this post wondering if Newegg.com is running a scam. To recap the Newegg.com scam, someone got my wife's credit card number, address, and email and then ordered a $1000 camera lens.I contacted Newegg.com and yelled at everyone I could speak with regarding their terrible fraud protection. Of course you think it is scam so you probably ignore it or maybe you think it is a gift. 2  Then the item shows up at your door which you open and to your surprise you are now the owner of some item you didnt order, but to your bank credit card, it looks like you actually bought the Newegg.com scam item.
A public key infrastructure (PKI) is the combination of software, encryption technologies, processes, and services that enable an organization to secure its communications and business transactions.
A cryptographic system that uses two keys -- a public key known to everyone and a private or secret key known only to the recipient of the message. When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message. Jane then uses her private key to decryptit. An important element to the public key system is that the public and private keys are related in such a way that only the public key can be used to encrypt messages and only the corresponding private key can be used to decrypt them.
