Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Overview of Node-safez

Node-safez is a security middleware for Node.js applications, providing automatic encryption and decryption of data in transit. Designed to work seamlessly with HTTP requests and responses, it ensures that sensitive data is protected from unauthorized access and interception by utilizing advanced encryption techniques.

This middleware integrates directly into Node.js servers, offering developers a simple yet powerful tool to enhance their application's security. By encrypting data before it is sent and decrypting incoming data, Node-safez maintains the confidentiality and integrity of data throughout its lifecycle.

Node-safez is configurable to meet diverse application security needs, providing flexibility in encryption standards and protocols to suit different levels of security requirements.

  • Employs industry-standard encryption algorithms to secure data during transmission.
  • Helps protect against data breaches and cyber threats, enhancing overall application security.

Implementation of Node-safez into Node.js applications is straightforward, promoting a secure development ecosystem without introducing complexity.

Installation

Add Node-safez to your Node.js project with the following command:


npm install node-safez or yarn add node-safez

Setup and Configuration

Integrate Node-safez into your application and configure it for your server's needs:


const { safezInterceptor } = require("@safez/node-safez");

Usage

After integration, Node-safez automatically encrypts and decrypts the data for all incoming and outgoing server requests.

Customizing Encryption per Request

Adapt encryption settings for individual requests by modifying request headers or server configurations:


app.use(safezInterceptor({ safezSaavi: "dummysecretkeyab" }));   

The optional values inside safezInterceptor are crypto type, configurable values are 'full', 'field', 'none'. When safezEnable is true, default value is full. When configured the safez, all your payload will be encrypted

Handling Errors

Effective error handling is crucial for maintaining the security and reliability of applications using Node-safez. Ensure that encrypted data errors are properly managed and decrypted for accurate troubleshooting and response.

Best Practices for Secure Error Handling

  • Encryption Secret Management: Keep your encryption secrets secure and inaccessible to unauthorized parties. Utilize environment variables or secure secret management solutions to store these keys.
  • Selective Encryption: Use encryption strategically to balance security needs with performance. Node-safez allows for selective encryption, enabling developers to choose which data requires encryption based on sensitivity.

Troubleshooting Common Encryption Issues

  • Syncing Encryption Keys: Ensure that encryption keys are consistent across all components of your application to avoid decryption failures.
  • Middleware Configuration: Verify that Node-safez is correctly initialized and configured before processing any requests to prevent bypassing encryption mechanisms.

Frequently Asked Questions (FAQ)

Address common queries about Node-safez to provide clearer understanding and guidance for integration and use.

  • Is Node-safez compatible with all Node.js applications?

    Yes, Node-safez is designed to be flexible and can be integrated into any Node.js application that handles HTTP requests and responses, enhancing data security regardless of the application's architecture or framework.

  • How can I exclude certain data or endpoints from encryption?

    Node-safez allows for customizable encryption policies. By configuring the middleware or modifying request handlers, you can specify which data or endpoints should bypass encryption, providing control over the encryption process.
