How can I do Base64 encoding in Node.js?

🚀 Base64 Encoding in Node.js 🚀

Are you struggling with Base64 encoding in Node.js? Don't worry, we've got you covered! In this guide, we'll walk you through the common issues faced by developers when dealing with Base64 encoding in Node.js and provide easy solutions to help you get the job done. Let's dive in! 💪

The Problem: Limited Output Options for cipher.final()

You might have come across the situation where you need to perform some cryptographic operations using the crypto module in Node.js. While the crypto module provides a wide range of encryption and decryption functionalities, you might find that the cipher.final() method only supports outputting hexadecimal, binary, or ASCII data. 😩

The Solution: Converting Hexadecimal to Base64

If you're looking to Base64 encode your encrypted hexadecimal output, we can easily achieve this by converting the hexadecimal data to Base64 format. Here's a step-by-step solution for you: 😎

1. After performing the encryption, use the update() method with the 'hex' encoding option to get the encrypted data in hexadecimal format.

var cipher = crypto.createCipheriv('des-ede3-cbc', encryption_key, iv);
var ciph = cipher.update(plaintext, 'utf8', 'hex');

1. Next, use the final() method with the 'hex' encoding option to get the final block of hexadecimal data.

ciph += cipher.final('hex');

1. Now, we can convert the hexadecimal data to Base64 format using the Buffer class in Node.js.

ciph = Buffer.from(ciph, 'hex').toString('base64');

1. Congratulations! You have successfully Base64 encoded your encrypted output in Node.js. 🎉

Decoding Base64: Choosing the Right Format

After encoding your data in Base64, you might wonder which format to use for decryption - hexadecimal or Base64? 🤔

The answer is simple! Since we have already converted the encrypted data to Base64 format, we need to use Base64 decoding during decryption. So, no worries! You can safely use Base64 for decryption. 👍
