Build your own Cryptography System using Python

Hello all!
I hope you are doing well in this tough situation! Let's pray that, the world recovers from this Pandemic as soon as possible.
In this video, we will create a mini project using Python! We will build our own cryptography system...
Privacy is a myth, thus to secure our communication over the network, we use cryptography. Go ahead and build your own cryptosystem and start a secure communication with your friends!

What is Cryptography?

Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it.

Plaintext: It is the data to be protected during transmission.

Encryption Algorithm: It is a mathematical process that produces a ciphertext for any given plaintext and encryption key. It is a cryptographic algorithm that takes plaintext and an encryption key as input and produces a ciphertext.

Ciphertext: It is the scrambled version of the plaintext produced by the encryption algorithm using a specific encryption key. The ciphertext is not guarded. It flows on a public channel. It can be intercepted or compromised by anyone who has access to the communication channel.

Decryption Algorithm: It is a mathematical process, that produces a unique plaintext for any given ciphertext and decryption key. It is a cryptographic algorithm that takes a ciphertext and a decryption key as input and outputs a plaintext. The decryption algorithm essentially reverses the encryption algorithm and is thus closely related to it.

If anyone are lazy to the point they dont want to type it out heres the code, it works on the latest version of Python so it should work for many other versions too!

def machine():
keys = 'abcdefghijklmnopqrstuvwxyz !'
Value = keys[-1] + keys[0:-1]

encryptDict = dict(zip(keys, Value))
decryptDict = dict(zip(Value, keys))

message = input("Please enter a Password")
mode = input("Please select an encryption mode : Encode(E) OR Decode(D)")

if mode.upper() == 'E':
newMessage = ''.join([encryptDict[letter]
for letter in message.lower()])

elif mode.upper() == 'D':
newMessage = ''.join([decryptDict[letter]
for letter in message.lower()])
else:
print('Please enter an Valid choice, Decrypt(D) OR Encrypt(E)')

return newMessage


print(machine())

Lottie animation stay safe stay home😂🔥🔥

why did you use an exclamation mark in the string? "alphabets !"?

[chromapixelgames]

Just Joined the family amzing video bro, make a video Secure atm machine system in Python

[vamsikrishnarao]

Bro do more videos on cryptography projects or some content!!👍✊

[Unknown_mallu]

Can u please explain this like how it is working while encryption and decryption

[pradipgundale]

I get error the term is not recognize as the name of cmdlet, function, script file, or, operable program veryfy the path is correct

[gourangGG]

What mechanism is used to encrypt and decrypt? md5???

[gowthamr]

By using which algorithm it's converting a cipher text?.. Can u tell me any crypto related project ideas for my minor project bro..

[panchalpavan]

if you want to store reverse of keys you can just do values = [::-1]

[shreyashmutyalwar]

I know this is just for fun, but on a serious note never ever use these simple algorithms in practice, always use certified and tested algorithms like Advanced Encryption Standard in real world applications!!

[yadlapallimeghana]

if we send the encrypted message to our friends, do they have to use the cryptography system with this exact same code to decrypt the message?

[ishaanagarwal]

Hey, bro how to add this thing on a website, or an app, how to integrate these codes with my website!!!!

[Sidhant_singh]

Which encryptic algorithm have you used?

[insaneguy]

Please make full course on it Otherwise Refer the resources in video Format.Regards.

[rohitjadhav]

Hey bro the video and content is awesome can you share some advance level cybersecurity project with source code

[onelove]

Anyone can clear why we will have space and exclamation mark in string

[ritikkaushik]

Can we use this kind of project in Resume??

[SanjaySingh-lflz]

elif is not recognised by python in my laptop

[syedamahnoor]

Can you share its github link with me?
