Reading message and decrypting with stream giving JavaScript heap out of memory

[GJakobi]

So I'm dealing with some large files (2GB) and I want to read the message and decrypt using Streams. I've seen some example codes but it's still giving out of memory error. Here is my current code:

Am I missing something?

Node: v20.10.0
openpgp: ^5.11.1

  async decryptFile() {
      const privateArmoredKey = fs.readFileSync('./private.pgp').toString();
  
      const privateKey = await openpgp.readPrivateKey({
        armoredKey: privateArmoredKey,
      });
  
      const filePath = './big_file.asc';
      const encrypted = fs.createReadStream(filePath);
  
      const message = await openpgp.readMessage({
        armoredMessage: encrypted,
        config: {
          allowUnauthenticatedStream: true,
        },
      });
  
      const { data } = await openpgp.decrypt({
        message,
        decryptionKeys: privateKey,
        config: {
          allowUnauthenticatedStream: true,
        },
        format: 'binary',
      });
  
      const writeStream = fs.createWriteStream(
        './big_file.txt.tar.gz',
      );
  
      data.pipe(writeStream);
    }

Hi, can you provide lib version and Node version?

Node: v20.10.0
openpgp: ^5.11.1

You are reading the file incorrectly: since it's armored data, you need to pass { encoding: 'utf8' } to createReadStream

Thank you so much!
