Decryption is functioning using php/openssl, and I can successfully retrieve my plain data. Here is the specific call that is defined:
<?php
function decryptString($data, $key)
{
return base64_decode(openssl_decrypt(base64_decode($data), "AES-256-CBC", $key, true, "h7oehNIHWGNIHxyN"));
}
function encryptString($data, $key)
{
return base64_encode(openssl_encrypt(base64_encode($data), "AES-256-CBC", $key, true, "h7oehNIHWGNIHxyN"));
}
echo 'encrypted: ' . encryptString('my sample text', '7f7720b911c2ecbb22637ed7adef41e82d44b6a0') . "\n";
echo 'decrypted: ' . decryptString('rFWejB1Pj6W3Gh1bheFqDZPMO9POKbhGPOP6eAH9BSk=', '7f7720b911c2ecbb22637ed7adef41e82d44b6a0') . "\n";
The output obtained from this code snippet is as follows:
encrypted: rFWejB1Pj6W3Gh1bheFqDZPMO9POKbhGPOP6eAH9BSk=
decrypted: my sample text
I attempted to replicate this function using cryptojs, but encountered errors such as "Malformed UTF-8 data" and other ambiguous issues. Here is the closest implementation I have achieved so far (currently facing a "Malformed UTF-8 data" error):
function decryptData(encrypted, pass) {
// encrypted is a base64 encoded string
let data = Buffer.from(encrypted, "base64").toString(); // Attempted this approach [ let data = crypto.enc.Base64.parse(encrypted); ]
let key = crypto.enc.Utf8.parse(pass);
let decrypted = crypto.AES.decrypt(data, key,
{
iv: crypto.enc.Hex.parse('h7oehNIHWGNIHxyN'), // Tried passing it as a simple string like this [ iv: 'h7oehNIHWGNIHxyN', ]
mode: crypto.mode.CBC,
padding: crypto.pad.NoPadding // Also tried with [ crypto.pad.Pkcs7 ]
}
);
let result = decrypted.toString(crypto.enc.Utf8); // Attempted this as well [ let result = decrypted.toString(crypto.enc.Base64) ]
}
Here is the error message that I am encountering:
/home/vagrant/PhpstormProjects/untitled3/node_modules/crypto-js/core.js:513
throw new Error('Malformed UTF-8 data');

Despite trying various suggestions, I remain perplexed and unable to resolve the issue. Any assistance or guidance would be greatly appreciated.
Relevant questions that I have explored without success:
- CryptoJS AES Unable to decrypt
- Encrypt with PHP, Decrypt with Javascript (cryptojs)
- AES decryption in crypto-js returns empty string
Update 1: I have provided a sample plaintext message, a complete php encryption/decription example, and the latest version of my code for reference.
