I am trying to decrypt a private key in a js step, then convert it to DER format and base64 encode it for use in a later Python step. I’m getting an error that suggests that it may be unsupported? This is the error I got: Failed to decrypt private key: error:1E08010C:DECODER routines::unsupported.

I have these imports:

import crypto from "crypto";
import { readFileSync } from "fs";
import { KeyObject, createPrivateKey } from "crypto";

and the error is coming from this function:

      const privateKeyObject = createPrivateKey({
        key: private_key_pem,
        format: "pem",
        passphrase: passphrase,
      });

Anyone know any work-arounds that don’t involve providing the key decrypted?

Hey , maybe your can try replacing raw \n character with the newline character

private_key = private_key.split(String.raw`\n`).join('\n'),

Thanks, Leo. I need to make progress with the workflows themselves, so I will come back to the private key later. I’m just using a secret to store the password.
