How to encrypt an image with chaos? Part 1 || Symmetric Encryption || Code in Python

Encryption consists of substitution and permutation method.

In this video, we will see the substitution method alone in an image.

Here, I am using the function explained in the previous video for generating the keys. Please visit the link below for the key generation function

For theoretical concepts of permutation and substitution, please visit the link given below

this is so nice code and well written by you 😊 and really very easy to understand

[tentoptucker]

It was really very useful, in future please make videos on hyperchaotic encryption also

[prasunsarkar]

which software is used to run these codes

[shyamkumar-sbim]

Why in encryption using np.zero after height and width there is a 4?

Import keygen as kg
Plz help me yae invalid arha h

[drkareem_shaik]

Can you make videos on normal text to polynomial conversion and apply it to chaos’s for encryption

[arpanmaity]

It is showing the error : module 'keygen' has no attribute 'keygen' please help

[WD_Weddesign]

hello! i have a problem with this code. when i am trying to run it i get this error enimg[i, j] = img[i, j] ^ key[z]
IndexError: list index out of range. can you help me? thanks

[maths]

And do you run the encryption deception at once ?

[sahiba]

Ma'am how long will be the key length

[ab-xgnt]

Why u make XOR between 1D key and 2D image(gray image)?!
I try implement as the code but by matlab, i generate key, then when i make XOR with gray image, i get error for dimentions .

[mehwish]

It works well when encryption and decryption are performed in a single program but when I try to decrypt the saved encrypted image, image is not decrypted properly.

helpful video i, m trying to implement the chaotic with CR4, DSE, AES if there anyone can help me so i can know the speed and time as well

[sakshamtiwari]

What is the app u are using for doing code in python and image encryption

[amruthaajithan]

Ma'am. Please mention about key space

[suhasinipandian]

hi i have a problem with this code. when i am trying to run it i get this error
File "C:\Users\91968\.spyder-py3\encryption.py", line 26, in <module>
enimg[i, j]=img[i, j]^key[z]



ValueError: could not broadcast input array from shape (3, ) into shape (4, )
please help me to solve the error
1.encrypted and decrypted images not showing in this window
2.key gen program only executed correctly

[gggggg]

Who have this problem "no module named keygen", open cdm and type "pip3 install python-keygen"
and other packages must be downloaded in the same way

I need this project how to contact you
