    Abstract: Now a days, it is sometimes not enough to keep the contents of a message secret, it may also be
necessary to keep the existence of the message secret, this is why we present in this study a combination of
cryptosystem algorithm and steganography. The proposed algorithm encrypts the information using
RSA algorithm before hiding it in image file to increase the complexity of encryption and decryption
process.
