enhancement - encrypt entire contents of json file about secure-config-tool HOT 1 CLOSED

Hi!

Encrypting the entire file (meaning ALL of its contents, keys & values) is not the original intention of my package @tsmx/secure-config and this supporting tool as it has some major drawbacks:

• the result would not be a valid JSON anymore
• the result would be completely unreadable for humans, which makes the handling extremely difficult

Since the additional gain of security is very small I defintively do not recommend to encrypt the entire file.

But: Nevertheless you can achieve your goal very easy with the provided library @tsmx/string-crypto which I also use in this project.

Encrypt an entire JSON file

const sc = require('@tsmx/string-crypto');
const fs = require('fs');
const jsonFile = require('test.json');
let encryptedJson = sc.encrypt(JSON.stringify(jsonFile));
fs.writeFileSync('test.json.enc', encryptedJson);

Decrypt the JSON back

const sc = require('@tsmx/string-crypto');
const fs = require('fs');
let decryptedJsonFile = JSON.parse(sc.decrypt(fs.readFileSync('test.json.enc').toString()));

Note: @tsmx/string-crypto by default uses the environment variable ENCRYPTION_KEY. If you need to use an environment variable with another name, simply pass the key directly...

sc.encrypt(text, { key: process.env['YOUR_VAR_NAME'] });
sc.decrypt(text, { key: process.env['YOUR_VAR_NAME'] });

Hope that helps!

Kind regards
