Preferred Abstract (Original): 

The RSA algorithm has some important parameters affecting its level of security. It is shown here that increasing the modules length plays an important role in increasing the complexity of decomposing it into its factors. This will increase the length of the public key and the length of the encrypted message making it more difficult to be decrypted without knowing the decryption key. However, the public key length has no major affect on the private key length. When the length of the message is changed then the length of the encrypted message will proportionally change, hence larger chunks are selected to obtain larger encrypted message to increase the security of the data in use.
