In the paper, the author has introduced a modified symmetric key cryptographic method, called algorithm SKG 1.2, for data encryption and decryption of any file using symmetric key at two stages, by swapping the characters in the string of text and by shifting the characters to left or right. The present method can be applied to encrypt any data consisting of 30 or more characters. The results obtained after application of algorithm SKG 1.2 are excellent and difficult to decrypt.
