Course outline
Overview
This module will briefly describe encryption which the learners should know before diving into encryption.
Prerequisites for Encryption
This module will focus on explaining the major prerequisites for encryption, such as cyber security, the need for cyber security, and cyber attacks.
What is Cryptography?
Cryptography is the study of techniques for secure communication between sender and receiver. Cryptography is also known as Cryptology.
What is Encryption?
Encryption is the process of securing digital data using mathematical techniques with the help of a key used to encrypt and decrypt the data. It basically converts plaintext into Ciphertext. Encryption protects private information and sensitive data between the client and the server.
Cryptography Vs Encryption
This course focuses on describing the significant differences between cryptography and encryption. The significant difference between Encryption and Cryptography is that encryption is the technique of securing sensitive data from hackers. In contrast, Cryptography studies techniques for securing sensitive data from hackers.
How does Encryption work?
The learner will understand the entire encryption process in this module.
What is Decryption?
Decryption is the method of converting cipher text into plain text. The reverse process of encryption is carried out using decryption keys.
Encryption Vs Decryption
This module focuses on describing the significant differences between encryption and decryption.
Types of Encryption
This module describes the types of encryption, such as symmetric and asymmetric encryption.
Symmetric Encryption is a type of encryption that uses the same secret key for encryption and decryption. It is further classified into block cipher and stream cipher.
Asymmetric Encryption is a type of encryption that uses a public key and a private key for decryption.
Encryption Algorithms and Protocols
This module will focus on explaining in detail encryption algorithms and protocols. A few popular encryption algorithms discussed in this section are Triple-DES Algorithm, RSA Algorithm, AES Algorithm, Blowfish Algorithm and Twofish Algorithm. This module discusses a few popular encryption protocols discussed in this section TLS/SSL, IPsec, SSH, and PGP.
What is Brute force attack?
A brute force attack is made to damage an organisation’s reputation or steals confidential information. A brute force attack is a trial and error procedure used by hackers to crack passwords and encryption keys to gain unauthorised access.

Encryption Basics Course
Encryption is a method of protecting data and communication from unauthorized access and manipulation. It is a crucial aspect of modern cybersecurity and has become essential in today's digital age. In this article, we will discuss the importance of encryption, its benefits, and its various uses.
Encryption is essential for safeguarding sensitive information such as financial details, personal information, and trade secrets. In today's digital world, there are numerous ways in which data can be intercepted and stolen by hackers or malicious entities. Encryption provides a secure method of communication by converting the data into an unreadable format, making it virtually impossible for unauthorized persons to access it. It is a vital tool for protecting personal privacy and keeping sensitive information confidential.
Encryption has numerous benefits that make it an essential tool in cybersecurity. One of the main benefits is that it provides secure communication channels, which is vital for businesses and organizations. Encryption can also help reduce the risk of cyber attacks by making it difficult for hackers to intercept data. Additionally, encryption can help prevent data breaches, which can be costly for businesses and can harm their reputation. Lastly, encryption provides data integrity, which ensures that the data has not been tampered with during transmission.
Encryption has many uses, ranging from protecting personal communication to securing data in businesses and organizations. It is commonly used to secure online transactions, such as online banking and shopping, by encrypting the data transmitted between the user and the server. Encryption is also used to secure email communication, ensuring that only the intended recipient can access the message. Additionally, encryption is used to secure wireless networks, cloud storage, and mobile devices.
In conclusion, encryption is an essential tool for ensuring the security of data and communication. It is a vital aspect of modern cybersecurity and is used in numerous ways to protect sensitive information. Encryption provides many benefits, including secure communication, reduced risk of cyber attacks, prevention of data breaches, and data integrity. As the digital world continues to evolve, encryption will remain a crucial tool for safeguarding information and ensuring personal privacy.
