Computer users are fairly familiar with encryption which is basically converting a readable information to what appears to be nonsense. Encryption is directly connected to the study of techniques for securing communication known as cryptology or cryptography. While cryptology aims for protection against adversaries that threaten confidentiality, authenticity, and integrity of data, encryption as we know it prevents unwanted people from getting hold of critical information through computer use. Decryption is about converting incomprehensible messages to their comprehensible form. The adversaries in this case are the cybercriminals who prey on weaknesses of computer passwords and laxness in electronic commerce.
In order to protect themselves, computer users have to maintain a certain degree of secrecy in their activities specifically in granting or withholding their approval for online transactions. Revealing too much personal information could pave the way for unwanted personalities to decipher protected passwords and codes. This is the reason why people are always reminded to be selective of what information to provide and to whom it is provided.
E-commerce usually makes use of the encryption protocol known as the Secure Sockets Layer (SSL). This is often seen in URLs starting with “https” instead of the typical “http”. Decryption is facilitated by the use of a “secret key”. Encryption also concerns itself in checking the trustworthiness of the source on any message.
Operating an online business will use e-commerce one way or the other. Encryption has made it possible for online businesses to be conducted. Without any secure means of financial transaction, very few customers will take the risk no matter how tempting the offer.
