Since e-learning totally depends on Internet, the transmission of mark sheet to the students from the administrator should be done very securely; otherwise, if the hackers reach the documents, then it may be very harmful for the students as well as for the corresponding e-learning institution also. By using, digital certificate the administrator can send the mark sheet securely to the students and also it helps in non –repudiation, one of the security issues in e-learning. The implementation of the object orientation model helps others in better understanding of the system. The other goals of object oriented implementations like code re-usability, data redundancy etc. can be madeby object oriented models. Here we will analysis the values of the metrics for two basic models of object oriented metrics: Chidamber and Kemerer metric (CK metric) and Metric for Object Oriented design metric (MOOD metric) based on the class hierarchy diagram of digital certificate transmitting from the administrator to students.
