Network security has become one of the major talking points in today’s technological world. Although several research activities were carried out pertaining to security in order to ensure confidentiality, authenticity, integrity, non-repudiation etc., there remained some loopholes which need to be taken care of. There are chances that cyber attackers or hackers may tamper or alter the texts and cause a severe leakage of confidential information of IT organizations, business firms, etc. Hence, it is of utmost importance to protect vital information from such attackers or hackers by using some standard techniques. In our paper, we have discussed the cryptographic techniques with proper encryption and decryption. We have suggested the use of Rail Fencing Cypher along with ASCII codes and mapping tables for end to end encryption of plain text comprising of several characters and then decrypting the encrypted text into plain text.
