You use symmetric encryption if you encrypt and decrypt data using the same key. Converting ciphertext back to plaintext is possible only if you have the right key with you. Converting data into unreadable text is called encryption, and reversing it back to plaintext is decryption.Ĭryptographic algorithms use a key to convert plaintext to ciphertext. To make information a secret, we use a cipher and an algorithm that turns plaintext into ciphertext. The three main components of a cryptosystem include plaintext, ciphertext, and algorithm. Hence only the sender and the receiver of that data can understand its content. It converts the data into a secret by converting plaintext into unreadable text and vice versa.

Cryptography is a study of techniques on how to keep the data secure. A Text editor such as Visual Studio Code.Ĭryptography is crucial for software development.Table of contentsĪ comprehensive understanding of cryptography and node.js is required before reading this article. Also, it will summarize cryptography in node.js. This article will help you learn how to use the Node.js crypto module to encrypt and decrypt data in your applications. Node.js has a built-in library called crypto for data encryption and decryption.Įncryption and decryption aim to enhance safety. Thus as a node.js developer, you should understand how to encrypt and decrypt data to secure data processed by your system.
When handling, moving, and storing data, you must do it safely and securely.
In the software development industry, developers use cryptography and encryption techniques to protect sensitive data from malicious parties.Ĭryptography is used to secure data stored in a database or transferred over a software development industry network. The more the data is accessed, the higher the threat to data security.
Web applications have access to large amounts of data that belongs to people, organizations, and governments.
