Great Node.js Encryption Libraries

Free Poster A2 Mockup Design PSD

Node.js A Javascript runtime built on Chrome’s V8 engine and backed by JS Foundation. It can run on both the server and the client. Node can be used to build scalable, high-performance, low latency web applications such as chat, Restful API, and web servers. For example, Node can make applications that have to deal with a lot of long-running connections more efficient.


One of the major concerns with using Node.js is security. Since Node.js is a server-side environment, vulnerabilities can compromise data on the server and even on other servers linked to the one running Node.js. Luckily, there are encryption libraries to mitigate security risks. A Node.js encryption library is a package of cryptographic techniques to encrypt and decrypt data. Node.js encryption libraries are useful for a variety of different purposes. Some common purposes include securing data in transit and storing data.

There are many Node.js encryption libraries, but here are the top Players in the market.

PKI.js

PKIjs is a pure JavaScript library implementing a number of formats and protocols that are used in conventional cryptography. It includes the formats that are used in PKI applications, such as RSA signatures and RSA encryption. It also has implementations for ASN.1, SHA, DSA, and X.509 digital certificates and can be used to create and verify RSA-PSS, ECDSA, and ECDH signatures.

io-ts

IO-TS has been created to be a runtime type system for IO decoding/encoding. IO decoding/encoding is the inherent opposite of processing and many IOT devices need a balance between the two. IO-TS is a secure, convenient and primitive technology for communication.

Xml Crypto

Xml Crypto is a library offering you the ability to sign, decrypt, and encrypt documents in the XML format in Node.js. The library can produce RSA signatures and RSA signatures compatible with DSA. With Xml Crypto you can operate on both large and small documents and progressiveness ensures you can process long and complicated documents without clogging up your resources. This library makes it easier to use XML with Node.js.

Iconv-Lite

Iconv-Lite is a library that is small but impactful. The library allows input from a string to be converted from one encoding to another which can be done quickly. This can be done in browser as well as in Node using as single line of code.

Jwt Decode

If you would like to decode the information stored in a JWT token, then JWT Decode will be the perfect tool for you. This stands for JSON Web Token, which is a coded object that represents a set of data. The JWT is a little like an envelope for holding all your sensitive data in a readable way in the form of credentials as the payload of the token.
