English Abstract

-The objective of this research is to study the idea of encryption and decryption data by using (RSA) and (DES) algorithm and comber between them.

The performance of this algorithm has been applied by using Delphi software program.

After implement the program it obtain the results in a form of windows, window show the transmitter side and one for the receiver side , another shows the values of the code.

And in order to obtain the outcome of this operation ,a few steps had be taken, starting with generating an encoding key to accompany the original data and then sending it to the receiving side that will analyze the encoding key to decode the message successfully.

The Encryption operation convert any character in the message to different numbers, by using encryption key ,in edition that Cannot receive the message or knowledge of its content, without using the same encryption code in the sender side .

And conclude that the (RSA algorithm )has a different length of code ( 1536-bit and 90-bit), in fact 1536 RSA is more secure than 90-bit because there is a need for massive memory to process the accounts, if the memory is not available, it means that the decryption process slow.

RSA is the most confidential of any of the digital signatures that can not be verified faster but for the exchange of confident communications networks the (DES) can be better.
