I have to set the environment variables(NODE_OPTIONS=--openssl-legacy-provider)

Because Noejs v17 use OpenSSL v3.0 and it remove a lot of algorithm cause my program can't run correctly.

Thank you.

This looks like a bug. Could you provide a sample program so I can reproduce it?

Best regards,

Roger

to nw.js

The example is as follows

<!DOCTYPE html>
<html>
<head>
<title>Example</title>
</head>
<body>
<script>
var cryptoNodejs = require('crypto');

var desKey = "A4ykcKJz";
var desIV = "zYt6D5TU";
var encryptedMessage = "PL9ulr7SG8s=";

var decipher = cryptoNodejs.createDecipheriv("des", desKey, desIV);
decipher.setAutoPadding(true);

var decryptedMessage = decipher.update(encryptedMessage, 'base64', 'utf8');
decryptedMessage += decipher.final('utf8');

document.write('Decrypted message is ', decryptedMessage);
</script>
</body>
</html>

In 0.58.0, the window will show "Decrypted message is Hello", but 0.59.0 will show as follows error message in console:

Uncaught Error: error:0308010C:digital envelope routines::unsupported
at Decipheriv.createCipherBase (node:internal/crypto/cipher:116:19)
at Decipheriv.createCipherWithIV (node:internal/crypto/cipher:135:3)
at new Decipheriv (node:internal/crypto/cipher:289:3)
at Object.createDecipheriv (node:crypto:146:10)
at chrome-extension://nacjpihodniapipnjlbloghmhecglemm/index.htm:14:29

Because OpenSSL v3.0 remove the des algorithm, the nodejs can set the environment variables(NODE_OPTIONS=--openssl-legacy-provider) to downward compatible.

So my question is how to set the environment variables of nodejs in nwjs?

Thanks.
