We implemented the image encryption algorithm described in the paper G.Ye,C.Pan,X.Huang,Z.Zhao,and J.He,“A chaotic image encryption algorithm based on information entropy,” International Journal of Bifurca- tion and Chaos, vol. 28, no. 1, p. art. no. 1850010, 2018.

There is also a paper indicating the flaws of the algorithm Cryptanalysis of a Chaotic Image Encryption Algorithm Based on Information Entropy The paper stated that many images on the internet have the same entropy. So, we give you image.bmp which has the same entropy as flag.bmp

Given these, it should be easy for you to decrypt the encrypted_flag.bmp, right?

The encryption service is running at x.x.x.x:oooo
