Describe the bug

It seems that aes-256-cbc implementation is broken.

Output (Node.js v18.20.3):

Link to the blitz that caused the error

https://stackblitz.com/edit/bug-stackblitz-nodejs-aes-encrypt-decrypt-8spnpy?file=index.mjs

Steps to reproduce

Open the StackBlitz terminal, and run the following command:

node index.mjs 12345678901234567890123456789012

Verify that the result matches the desired outcome from any third party AES, or run the docker container with node.js of the same version.
You can verify the results in CyberChef

Expected behavior

node index.mjs 12345678901234567890123456789012
