In this paper we tend to square measure handling Steganography victimization SHA-256 algorithmic program within the past we tend to used LSB algorithmic program. LSB(Least vital Bit) it's totally different results on 1bit and 2bit models .The use of additional bits affects the smoothness of image on stego image . Message is tough to recover if the image is subject to attack like translation and rotation. it's simple to decode to the hackers(other than WHO we tend to sent ) .Message is well lost if image is subject to compression like JPEG, however solely such image kind is accepted by this algorithmic program. thanks to these drawbacks we tend to square measure moving to SHA-256(Secure Hash Algorithm), it's a scientific discipline hash additionally called digest .It enhances the extent of security in concealment of covert information exchange and data concealing .It generates a singular 256 bits (32 bytes) code of a text ,more secure than different common hashing algorithmic program. it's quick to calculate, immune to preimage and second preimage attacks and collision resistant. LSB algorithmic program has additional probabilities to be decrypted has it's coded with prime quantity combination therefore it is decoded simply.
