One feature that is often used to do this is e-mail or e-mail which can send and receive exchanged information quickly compared to conventional letter sending. However, sending e-mail has shortcomings in terms of security which is vulnerable to eavesdropping, fraud and other things. PT Cipta Rasa Multindo is one of the many companies that uses this e-mail feature to exchange information and quite a lot of information sent via e-mail is confidential. Therefore, it is necessary to create a method or application that can help with security in sending information via e-mail so that PT Cipta Rasa Multindo is safer in sending information, especially confidential sending.
