Unit 5 Assignment Security and File Processing

The Python programming language has a simple syntax that is popular among programming learners as well as experts (Adawadkar, 2017). It is also a high-level language, making it easy for humans to understand as compared to machine and assembly languages which are low-level programming languages. Python has an extensible interpreter and a vast library, making it efficient. The language can be used with other applications by embedding it.

Highlight any aspects of security that are unique to the Python programming language.

Python programming is recommended for cybersecurity (Wang et al., 2020). It offers web security for web browsers. Because of its highly effective data security features, Python is used in computer vision, big data, robotics, automation testing, and machine learning (Wang et al., 2020). Python also offers high memory safety. This is implemented through MesaPy. The Python programming language also has a simple syntax that makes documenting code easy and fast.

Identify several methods for securing data in Python software.

To ensure that Python programming is kept safe, MesaPy should be used (Wang et al., 2020). MesaPy is a Python interpreter that is memory-safe. This memory-safe interpreter reinforces security in PyPy, where the interpreter was developed using the C and C++ programming languages. Data encryption packages can also be used to secure data in Python. This ensures that a hacker or a malicious person does not have access to the data. Some of the encryption packages in Python include cryptography, hashlib, and simple-cript (Sharma, 2020). An encryption key and decryption key are known to both the sender and receiver. The data encryption packages facilitate the importation and execution of encryption functions such as fernet and hash.

Address the role of data encryption across the Internet.

Data encryption and decryption are done under cryptography (Gençoğlu, 2019). Encryption facilitates the encoding of a message from plain text to unreadable format. The encrypted message is then transmitted from the sender to the receiver. Upon reaching the sender, the message is decoded and returned into plaintext for the receiver to read. A sender encrypts plaintext with an encryption key that requires the receiver to have a decryption key (Gençoğlu, 2019). The encrypting and decrypting exercise is necessary to ensure that only authorized parties can read a transmitted message. The Internet has a large web of computers where hackers might pose as legal persons with the intent to intercept or eavesdrop on a message in transit.  Therefore, data encryption keeps hackers and all other cybercriminals at bay.

Identify any packages built for Python that facilitate data encryption.

Cryptography is one of the packages used in Python for data encryption and decryption (Sharma, 2020). To use cryptography in Python, the Fernet function is imported. An encryption key is generated and loaded before data is encrypted. During data decryption, the key that was used to encrypt data would be used. Simple-crypt is another package that is used in Python to encrypt data (Sharma, 2020). The decrypt and encrypt functions are used under the simple-crypt package. These functions are used to decrypt and encrypt data in Python. Hashlib is the third Python library used in encrypting data (Sharma, 2020). The hash function accepts input in the form of variable length and provides an output of fixed length. This ensures data integrity and safety.
