[SOLVED] cryptography and steganography - URGENT HELP NEEDED PLEASEEE
I and my team mate have been doing my project in steganography for college work
All we wanted to do was to encrypt some text and store it in an image. then extract the encrypted text and decrypt it.
for cryptography -we used RSA algorithm
for steganography - we used LSB algorithm
I have implemented steganography algortihm. It works good.
My friend has implemented rsa algortihm. It also works fine
But the issue is when we are integrating both of them, we are getting errors.
Dont know why??:confused::confused::confused::confused::conf used:
The issue is we are storing and extracting the file of encrypted data. We are getting THE SAME FILE WHEN WE ARE EXTRACTING IT FROM THE IMAGE.
BUT when we are decrypting it, we are not getting the proper result and are getting some different symbols. I think non-ascii characters. why is this happening??
That is if we decrypt the output of encryption directly, we are getting the result. but when we are applying steganography and getting the SAME encrypted file and decrypting it, we are getting these different symbols.
Why is this happening??
Anyone got any ideas???
I have to resolve this and submit it in two days!!
Pleaseeeeeeeeee help me out!!
Any kind of help is appreciated!!
