In this paper, the author has introduced a unique cryptographic method, called algorithm SKG 3.00, for data encryption and decryption of any text file at four stages first, by converting each character into corresponding binary code using 8-bit ASCII code thus the authors get 8N bits for a text of N characters. Secondly, creating a string of 0's and 1's such that total number of 0's and 1's is 8N, the consecutive numbers of 0's and 1's in this string may be from 1 to 7. Thirdly, using control NOT gate on binary strings obtained at stages one and two and finally, converting binary string obtained at stage three into corresponding characters using 8-bit ASCII code.
