At the present time, information security has become very necessary and is considered a very difficult problem in the event that it is exposed by the attackers and becomes easy and available to them. Therefore, data protection and non-disclosure to unauthorized persons are required to do so. The solution is to encrypt it and there are a large number of encryption algorithms in use. In this paper, both the RSA generic encryption algorithm and the hash algorithm known as SHA256 were used, in which the RSA algorithm was improved by generating the algorithm keys from an image generated with the SHA256 hashing algorithm. Where two keys are formed, one of which is public for encryption and is available and the other is a private key that is not disclosed only to the person who has access to the message, and effective encryption of the data was produced in addition to the retrieval of the original text. The proposed method has been programmed in VisualBaic.Net 2012 language.
