I believe on line 5 the intended code is var crypted = cipher.update(data, 'utf-8', 'hex');. text is not defined in the scope of the encrypt function.
Thanks!!!
Thanks !! This code is very good and very easy to use Thank you BOSS
Thank you! The W3C example is either outdated or deprecated. I appreciate the example.
Bear in mind that this example does not define an Initialization Vector (IV) which can lead to security issues.
Have a look on Node Crypto method description
"encrypt": function ('password'){
var key = "123|a123123123123123@&";
var cipher = crypto.createCipher('aes-256-cbc', key);
var crypted = cipher.update(data, 'utf-8', 'hex');
crypted += cipher.final('hex');
return crypted;
},
"decrypt":function('password') {
var key = "123|a123123123123123@&";
var decipher = crypto.createDecipher('aes-256-cbc', key);
var decrypted = decipher.update(data, 'hex', 'utf-8');
decrypted += decipher.final('utf-8');
return decrypted;
}
#All: You can use this code after a bit changes.
Thank you, this code is easy to understand and use.
Great it helps me a lot thank you bro
Why theres not IV defined? Am I missing something ?
@XaooB
Use function createCipheriv and createDecipheriv to encypt and decrypt file with random IV if needed.
if you take an encrypted value using this method, and start the script anew, providing that value, it won't decrypt it correctly. How can you take an encrypted value and then decrypt it by starting the script anew?
@nazariyv first, there was a copy/paste error in Line #5 which I just fixed.
Second, what do you mean it doesn't work correctly after starting it again? Assuming you specify the exact same key and the right encrypted output it should decrypt it without a problem.
Thank you!
