What does Encryption mean?
Any information about your credit card may be at risk, especially when processing transactions over the internet. Nowadays these kinds of transactions have become very popular, and given the comfort these offer and the ease in handling them, more and more people choose it. Now, in order to stay somewhat secure, one needs to encode the information of their credit cards. You can encrypt these personal data by using CBC- or Cipher Block Chaining or Counter mode, and basically never rely only the fact that the website you visit for online shopping is SSL secured because that gives you indeed protection but only for the time being.
