When we talk one to one that is called human language that is called plain text or normal text. When we talk in normal text or plain text, then all human can understand this text or language easily. That is why we create a cryptography security system to convert this plain text to cipher text. In this security system, we use both number and English alphabet for encryption and decryption the text to hide the plain text. In this security system encryption is mainly depend upon the key generation. The main goal of this security system is to convert simple message or text to non-readable text to secure the messages from hackers; this is called decryption. In this project, at first we find the ASCII value and binary value of the number and alphabet then after all calculation of this value we find the encrypted value and using this value we find decrypted value. In this project, we use RSA and DES and Cryptography for doing encryption and decryption. Moreover, use the ASCII number. In improvement, we complete the whole key generation and encryption and decryption process, which will take linear time.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
