RSA Example Application for 5685x

Overview

The demo is based on File I/O. The file m.in is used to store message words for RSA. After encryption, the

coded message is stored in m_Enc.out; after decryption, the decoded message is stored in m_Dec.out. The

contents of m_Dec.out must be the same as that of m.in. The contents of the input file (i.e., the message)

could be text, numbers and/or special characters.
