If you run any type of online business where you will be collecting personal information from your customers such as their names and addresses or even more importantly their credit card or banking information, you must take the appropriate steps to protect it. One of the most common and successful methods of doing this is by using a digital certificate issued by a Certificate Authority such as Digi-Sign.
When you are issued a digital certificate, the information that your customers enter on your checkout page will be encrypted using the very latest in SSL security. The only way that anyone can decrypt the information is to have the matching key to the one that was used to encode it and that is only given to the person who has the digital certificate. Anyone else who tries to access the information will see nothing but gibberish that they cannot decrypt.
