Error Message “Error:0308010c:digital Envelope Routines::unsupported

When working with JavaScript, you may come across the error message “error:0308010C:digital envelope routines::unsupported”. This error typically occurs when trying to use certain cryptographic functions that are not supported by the version of OpenSSL being used.

There are a few potential solutions to this error:

1. Update OpenSSL

The first solution is to update OpenSSL to a version that supports the cryptographic functions you are trying to use. This can be done by following the official OpenSSL documentation for your specific operating system.

Here is an example of how to update OpenSSL on a Linux system using the apt package manager:

sudo apt update
sudo apt upgrade openssl

2. Use a Different Cryptographic Library

If updating OpenSSL is not an option or does not resolve the issue, you can try using a different cryptographic library that supports the functions you need. One popular alternative is the Node.js built-in crypto module.

Here is an example of how to use the crypto module to encrypt and decrypt data:

const crypto = require('crypto');

const algorithm = 'aes-256-cbc';
const key = crypto.randomBytes(32);
const iv = crypto.randomBytes(16);

const cipher = crypto.createCipheriv(algorithm, key, iv);
let encrypted = cipher.update('Hello, World!', 'utf8', 'hex');
encrypted += cipher.final('hex');

const decipher = crypto.createDecipheriv(algorithm, key, iv);
let decrypted = decipher.update(encrypted, 'hex', 'utf8');
decrypted += decipher.final('utf8');

console.log('Encrypted:', encrypted);
console.log('Decrypted:', decrypted);

3. Check for Compatibility Issues

If neither updating OpenSSL nor using a different cryptographic library solves the issue, it’s possible that the specific cryptographic functions you are trying to use are not supported by the JavaScript runtime environment you are using.

In this case, you should check the documentation and compatibility of the functions you are using to ensure they are supported by your runtime environment.

By following these solutions, you should be able to resolve the “error:0308010C:digital envelope routines::unsupported” error and continue working with JavaScript cryptographic functions.
