Simple encryption algorithms in Python – Introduction to the principles of cryptography in Python

Herbert Huffner

Python is the name of a programming language. This means that it is a structure for expressing the programmer’s ideas or commands to the machine.

Cryptography in Python is interpretive, high-level, multi-purpose, object-oriented and reflective, and open source. Did you understand something? What is the program that is being written? Remain interpretive and high level text.

The name comes from a British comedy group called Monty Python. Python crypto creator Guido van Rossum enjoys the comedy group’s performances as the language develops.

References The currents and terms of this comedy group have been used in writing the Python cryptographer.

The latest version is released for December 2019. In previous versions 3.5 .py, .pyi, .pyc, .pyd, .pyo and later .pyw, .pyz was the name of the encryption file in Python.

 

Encryption in Python

 

In computer science, programming is defined as the process of converting a problem-solving formula or computational algorithm into an executable program (software). A programming language is actually a visual language that contains words. The letters taken from an alphabet have formed these words and languages ​​in a figurative way according to a set of rules.

Computer languages

A set of rules that produces a variety of outputs. Computer languages ​​are used to implement and execute algorithms. So whatever it is, we are faced with instructions.

We want to know what these guidelines are and, more importantly, how they can be interpreted. It depends on the intelligence of the programmer.

Cryptography combines letters and words in human language and literary poetry with the programmer and the code they pick and the collections they make.

machine learning

Perhaps the best way to explain machine learning is to use a simple example. Suppose you want to write a program that automatically or automatically detects something in a photo. You want to write a program that recognizes an object in a photo. Machine learning usually goes from the pattern of inputs it receives to an algorithm for detection and execution.

That means you can give 1000 A photos and 1000 B photos to a machine learning algorithm. In this way it recognizes the difference between A and B well. Now if you give him a new image A or B he will be able to identify them well. Encryption in Python and its draft library, the code and algorithms at your disposal, are used to solve these seemingly simple problems to launch large projects that can be designed through encryption in Python.

Object orientation and its reflection in Python cryptography

Well, then we got the point that cryptography in Python is high level and interpretive. Another term used to describe cryptography in Python is object-oriented. Object-oriented, known by the acronym OCP, is actually a programming paradigm. As high level and interpretations were considered a paradigm.

Paradigm

Here is how to categorize programming languages ​​based on their features. Objectists work on the basis of objects. The object can be data or codes.

In this category of programs, data and codes are grouped together as much as possible in a format called object and form a unit (object) that is relative to the encapsulation environment (Encapsulation). Encapsulation allows objects to work together without knowing how they work together.

This is how cryptography works in Python. The object-oriented programming technique is far more efficient and sophisticated than the function-based programming style.

Reflection

Cryptography has a capability that acts as a process. A process for testing, recognizing the type or properties of an object during execution, as well as modifying the structure and behavior of the object itself. This means that cryptography in Python is a reflection.

The reason for the popularity of Python encoder

Cryptography in Python is free, and more importantly, cryptography in Python has a library of standard and pre-written interpretations for its users that are available to everyone on an up-to-date basis. We can donate standard interpretations to the Python Library Library. This is useful for other developers. It will also help you spend time and money.

Python Encryption Library

In fact, many of the routes to be taken are available by default in the Python cryptographic library. Cryptography in Python looks amazing. The keywords of this language are minimal and are very large compared to the libraries available to the user. Cryptography in Python is especially popular with those who are new to programming.

 

 

Going back to the top, it is emphasized: “There is no right or wrong answer” means that Python encoder is not necessarily a good language to start with. If the field you are studying does not read in this language, or you are not personally interested in this language, you should try other languages ​​to get started.

Encryption in Python is high level

Cryptography in Python is a level that is called a high level based on its abstract value and compared to another level in an analogy. The same language is low level compared to human language. However, with this low level, it can produce programs that human language is not capable of. So the debate is over the use of a language, otherwise high-level language is not superior to low-level.

 

 

The farther a language is from the “machine language”, the higher the level. High-level language needs an interpreter and translator. There is also another concept called compile. Compile converts one computer language to another.

 

Compilers must be able to read valid source program instructions and create a match in the target program. But a translator translates one language into several languages. To translate, we need another program to read and run these.

Other languages ​​such as Perl, Ruby, and MATLAB are examples of these programs that are interpretive-translational.

Cryptography in Python is one of those high-level programming languages ​​that pursues specific applications. Cryptography in Python, although high-level, is just to start with the legibility of written code and draft code. But in order to be able to create an up-to-date application with encryption in Python, you need knowledge and experience.

Application of Python encoder and labor market

Applications of Python encryption in scripting (for use on servers), building web applications, data analysis, computer games, and artificial intelligence are some of the applications of Python encryption. Given that Iran is developing, cryptography can be a very good job market for those interested in this field.

There are many reputable software companies that use Python. Of course, this does not mean that it was all written with the same cryptography, but it was used. Some of them:

 

 

The largest share of domains in the use of Python cryptography, academia, electronics and governments have the largest share

How to write a program

To start encryption in Python, first install Python on your operating system version. Usually, you will find step-by-step tutorials in this field by searching on Google, and the Python website has provided it to the user for free. But before you install, know that on some versions this program is installed by default, such as Mac and Linux.

 

For the Windows operating system, click the Start button and type Cmd to open the command prompt. Type python in the same window. If you have a version of Python installed as shown, you will see a similar message.

Before you start learning cryptography in Python, you may want to know which integrated software development (IDE) environment and text editors to choose from to make Python editing easier, and search between introductory books or sample reviews. Provides code that may work for your Python encryption project.

 

 

Everything is available on the Python website to learn cryptography in Python. You can even find instructional videos with subtitles that can be used for the encryption experience in Python.

PyCham

In addition, encryption in Python is interpretive, and you must select the IDE program. There are many diverse development environments (IDEs). The first limiting factor is the choice of programming language. Here, cryptography in Python is our preferred language, so we have to choose our development and editing environment accordingly. The most famous of these is PyCham.

Do not confuse yourself to begin with and let your brain gradually recognize the differences. Cryptography in Python is vast and you have to go step by step. Python Encryption is also known for its extensive free services.

 

 

After downloading and installing the Windows version, go to the command prompt and type python. If you start, you will receive a message according to the photo. One of the simplest commands in Python is the print command. In front of the arrows we type:

The first line (circle) is the command we give. The program runs and our command is printed.

But this performance is in vain. So we go to the development environment. Visual Studio is a text editor that can run Python code. Finally get to know PyCham better.

Free educational space

The good thing about cryptography in Python is that its training space is free. Many sources can be found in English and Persian. One of these resources is Mohammad Ardokhani 19-hour training that you can follow for free and with fluent and simple language up to an advanced level.

Also course 57 !!! The watch can be downloaded from Jadi Mirmirani, whose home school website has this training in its courses. You can get acquainted with this programming language in a practical and applied way. There is a very, very extensive article about Python cryptography training that you can access with a few clicks.

 

 

Books have also taught Python cryptographers step by step. In fact, you will not find any problems in this regard, and it is important to follow yourself in a purposeful way to make cryptography in Python your skill.

If you want to become a professional in Python encryption, it is better to improve your programming skills and general knowledge. Having the skills in the following chapters is one of the pillars of success in this field:

Must know about:

  1. Python encoder and version differences
  2. Web frameworks
  3. Object-relational mappers
  4. Understand multi-process architecture
  5. Restful APIs
  6. High communication ability
  7. Have high design ability.

It is better to know about:

How long does it take to learn Python Encryption?

The time it takes to learn cryptography in Python depends on many circumstances. Whether your first programming experience was the same cryptography in Python or a programming history in other cryptographies such as Java. But let’s draw a time-table:
