This paper suggests the padding algorithm using padding character length to concatenate more than one string without side-effect. Most existing padding algorithms padding null character in the empty location could not discriminate the real string from the padded character. To overcome this problem, in this paper, the padded character contains pad character length information. This mechanism is working better than NULL or '00' padding cases. The suggested padding algorithm could be effective for data encryption and decryption algorithms.
