摘要：communicating over any untrusted medium or network requires privacy and authentication;cryptography plays an important role in this area. Original Playfair cipher is one of the earlycryptographic algorithms that uses a 5x5 matrix. It supports English language merely and can becracked easily. It has being improved in different aspects. This paper, firstly, improves the algorithmto support the Kurdish language script. This is achieved by using a 256X256 matrix that meanwhileincreases the security of the algorithm dramatically. Secondly, the proposed algorithm is coupled witha hash function (sha512) to achieve user verification. For this a software is designed and implementedbased on software development concepts
