Java，移除PDF密码并返回字节数组

import org.apache.pdfbox.pdmodel.PDDocument;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;

public class PDFPasswordRemover {
    public static byte[] removePassword(File pdfFile, String password) throws IOException {
        try (PDDocument document = PDDocument.load(pdfFile, password)) {
            if (document.isEncrypted()) {
                document.setAllSecurityToBeRemoved(true);
            }
            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
            document.save(outputStream);
            return outputStream.toByteArray();
        }
    }

    public static void main(String[] args) {
        File pdfFile = new File("path/to/pdf/file.pdf");
        String password = "password";

        try {
            byte[] pdfBytes = removePassword(pdfFile, password);
            // 处理返回的字节数组
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
