decrypting a bmp image
hi all,
my project is on how to encrypt/decrypt BMP and JPEG image files.i have some idea about this.
One simple way to encrypt a string of character data or binary data is to form a "random" string of bits as long as the original "message," and "exclusive or" (XOR) this random string of bits with the original message to give an "encrypted message." If the receiver of the message knows how to form the same "random" string of bits, a second "exclusive or" of the random string of bits with the encrypted message will decrypt the message.
if anyone has more suggestions,pls help me.reply me as early as possible.i want to know about the encryption algorithms best suitable for this project.
regards
john
