# Cryptography Projects in Python

A technology called cryptography, which is motivated to protect the information in communication channels using techniques that work based on mathematical operations. The cryptography technique is nothing but a set of rules resultant from math theorems for establishing secure communication. To protect the information in-network, it applies encryption and decryption methods. Did someone is looking for the best cryptography projects in python along with the latest research information? Then this page presents you with your required information!!!

In other words, network admin set the security policies to protect network information from malicious activities like security attacks, data alteration, data exploitation, unauthorized access, resource inaccessibility, etc.

## What is cryptography in Python?

The process that is used to store and transmit information in a secure way is known as cryptography. By the by, it enables you to transfer encrypted data from one computer to another computer in the same network or different network via the Internet. On the receiving side, the receiver can decrypt the data to know the original data.

To easily implement all these processes, python offers several cryptography packages. These packages are enriched in various libraries and functions to simplify the code complexity. So, the cryptography projects in python are simple to design and development.

### Is Python used in cryptography?

To support cryptography, python offers a special library called “cryptography”. This cryptography library is well-equipped with both encryption and decryption functions. Through these functions, a developer can easily implement cryptographic techniques and other related concepts. To use python-enabled cryptographic functions, install cryptography library/package by typing the below command in a python shell or command prompt.

• Installation Command
• pip install cryptography

By the by, python is not only limited to the “cryptography” library but also supports several libraries/packages to handle different sorts of cryptographic techniques and models. Our developers are skillful to work on all supportive python libraries to create innovation in the cryptography field.

So, we are adept to recognize suitable libraries based on your project requirements in network security projects. Here, we have given you some important libraries that are largely used in cryptography projects in python. To know essential libraries for your handpicked project, communicate with our development team.

#### Python Libraries for Cryptography

• Cryptography
• PyCrypto library
• Bit
• Platform-Agnostic Security Tokens (PySETO)

For illustration purposes, here we have taken the “Bit” library as an example. It is an intuitive bitcoin library that is encouraged by Keras and Requests libraries. By the by, it is popularly known for its developer-friendliness nature to implement cryptographic techniques. Likewise, other libraries are also more useful for cryptography development in their way. While project development, one should know the usability and purpose of each library before importing libraries into the project. Since the best selection of libraries make you reduce the code length of the project without compromising accuracy in project results

Further, we have also given you some key characteristics of python which make python more famous in the cryptography field. In comparison with other software, python has numerous unique characteristics. Although python is initially intended for general-purpose applications, now these characteristics make python as most powerful software in many research fields.

Let’s have a quick look over the unique qualities of python in cryptography projects

• Software Requirements
• Python 3.5
• PyPy3.5-v5.7.1
• PiP – pip 8.1.2 or above
• Operating system – Mac OS, Windows, and Linux
• Installation Command
• \$ pip install bit

As mentioned earlier, the cryptography library majorly focuses on cryptography projects in python to improve security over digital information. Specifically, it supports different cryptographic methods efficiently. As well, it turns out to be a standard cryptographic library for dealing with complex security issues in cryptography. Moreover, use PyPy3 7.2+.and Python 3.6+ to install this library.

Generally, cryptography methods are implemented based on low-level interfaces and high-level formulae. For instance: message digests, digital signature, key derivatives, symmetric ciphers, etc. Further, it also supports different types of cryptographic algorithms,

## What library can provide AES to Python?

PyCrypto library

PyCrypto library is used to develop and execute the AES algorithm. This library stably acts as a dependency for the AES algorithm. By the by, you can also directly implement AES through pure python in the case of theoretical AES primitives

Further, you need a key for executing the encryption process. In general, encryption supports two types of keys as symmetric key and asymmetric key. Based on the project requirement, select any of those keys for encryption.

Generally, cryptography techniques work on the principle of encryption and decryption processes. Here, these two processes are intended to protect data from third parties who wish to do malicious activities. Let’s see exactly what is encryption and decryption and by what means these processes are implemented in python

### How to perform encrypt and decrypt in Python?

• Encryption
• It encodes the input information using an encryption key
• Decryption
• It decodes the input information using a key that is used for the encryption process

Symmetric-key Encryption using Python

The information that encrypts and decrypts using the same key is known as symmetric-key encryption. Although it is a simple method to execute, it lacks security. It has the thread of stealing the key while transmitting data with the key. So, it requires more safety measures to protect both data and keys from a middle person in implementing cryptography projects in python. For instance: the Fernet module

Fernet module

This module gives high security over encrypted data. It makes sure that no data is manipulated/viewed by third parties. Further, we have given you the import steps and working process of the fernet module. In addition, we have also included the code to import the fernet module from the cryptography library in python 3.

• Installation Command (cryptography library)
• pip install cryptography
• Working Procedure
• At first, import the Fernet module
• Next, create a single key for both the encryption and decryption process
• Then, convert input data from string to byte string for encryption
• After that, for instance, Fernet class along with key
• Next, encode the string by using the Fernet class instance
• At last, decrypt the encoded string with Fernet class instance (using same encryption key)

Python3

from cryptography. fernet import Fernet

message = “hello geeks”

Asymmetric-key Encryption using Python

The information that encrypts and decrypts using two different keys as public and private is known as asymmetric-key encryption. Here, the public key is responsible for data encryption and the private key is responsible for data decryption. Relatively, it is more secure than symmetric key encryption.

As the name suggests, the public key is open to all where anyone can view, but the private key is not open to all. So, it gives high security to both data and keys from a middle person. For instance: the RSA algorithm. Further, we have provided you with the installation command and working process of the RSA library. And we have also given you the code to encrypt and decrypt data using RSA in python 3.

• Installation Command (RSA library)
• pip install RSA
• Working Procedure
• At first, import rsa library
• Next, create both public and private keys using rsa.new keys() for the encryption and decryption process
• Then, convert input data from string to byte string for encryption
• After that, use the public key to encrypt byte string
• At last, use a private key to decrypt the encrypted string
• Overall, the encryption process takes place by a public key, and the decryption process takes place private key

Python3

import rsa

publicKey, privateKey = rsa.newkeys(512) /* key length at least of 16

message = “hello geeks”

rsa.encrypt()

rsa.decrypt()

Last but not least, now we can see about the future research scope of the cryptography projects in python field. The majority of next-generation cryptography in information and network security is dependent on the following technologies. So, these technologies earned more attention in the active research community. On knowing the huge demands of scholars, we have collected several cryptography areas which have a high degree of future research opportunities. Additionally, we have also framed an abundant amount of project ideas in each area. For your information, here we have given you some sample technologies.

### Quantum Cryptography

• Quantum cryptography is an innovation in the cryptography field
• Data is stored in the form of binary values (0 or 1) in modern computers
• This binary format is replaced by multi-state quantum superposition in quantum computers
• As well, multi-state quantum superposition is stored in the form of quantum values (qubits or quantum bits)
• Additionally, it enables mathematical computation at different magnitude orders which is speedier than conventional techniques

For illustration purposes, here we have taken “quantum key distribution” as an example. This is one of the important quantum cryptography techniques to solve key exchange issues. Similarly, quantum cryptography provides appropriate solutions for various issues which not done by conventional techniques.

One special feature of quantum cryptography is the quantum state. If someone attempts to break encrypted data, then the wave function gets disturbed and changes the quantum state. This helps to find eavesdropping/man-in-the-middle attacks in quantum key distribution. For instance: Shor’s algorithm
