<![CDATA[Cryptography is essential in information system. It provides information with a guarantee in its accuracy and secrecy. Cryptography can prevent deception in e-commerce and protect the legality of a financial transaction. It keeps identity originality and keeps an identity a secret. It also prevents acts of damaging documents and protects them from competitors or irresponsible parties. On the contrary, many of cryptography products on the markets do not emphasize on safety level. Many of those are not designed by cryptographers but by technical engineers who do not view cryptography as the essential part. A secure system cannot be designed only by “giving/attaching” cryptography inside but by knowing the procedures inside the system starting from its concept until it is attached on. Millions of Rupiahs has been spent for computer security. Yet it seems ineffectual since computers are still insecure. A powerful and weak cryptography product looks alike. Two e-mail encryption products look the same. One is secure while the other is fragile. After being tested, both programs have specification similarities. Only there is one with security holes. A well-experienced cryptographer and criminals can only see this discrepancy.]]>
