How to hide file names with password inside zip password protected archive using zip4j
问题
Sure, here is the translated code segment:
我想要用带密码保护的压缩档案来压缩文件。我有以下实现：
public class ZipArchiverAdapter implements ZipArchiverPort {
private static final Logger log = LoggerFactory.getLogger(ZipArchiverAdapter.class);
@Override
public void compressFilesWithPassword(List<String> fileToZipPaths, String password) throws IOException {
String sourcePath = System.getProperty("java.io.tmpdir") + "supportPackage";
String destPath = sourcePath + ".zip";
System.out.println("Destination " + destPath);
ZipFile zipFile = new ZipFile(destPath, password.toCharArray());
for (String f : fileToZipPaths) {
zipFile.addFile(new File(f), getParameters());
}
}
private ZipParameters getParameters() {
ZipParameters zipParameters = new ZipParameters();
zipParameters.setCompressionMethod(CompressionMethod.DEFLATE);
zipParameters.setCompressionLevel(CompressionLevel.ULTRA);
zipParameters.setEncryptionMethod(EncryptionMethod.AES);
zipParameters.setAesKeyStrength(AesKeyStrength.KEY_STRENGTH_256);
zipParameters.setEncryptFiles(true);
zipParameters.setIncludeRootFolder(true);
return zipParameters;
}
}
Please let me know if you need further assistance.

I wanna zip files with password protected archive. I have such imp:
public class ZipArchiverAdapter implements ZipArchiverPort {
private static final Logger log = LoggerFactory.getLogger(ZipArchiverAdapter.class);
@Override
public void compressFilesWithPassword(List<String> fileToZipPaths, String password) throws IOException {
String sourcePath = System.getProperty("java.io.tmpdir") + "supportPackage";
String destPath = sourcePath + ".zip";
System.out.println("Destination " + destPath);
ZipFile zipFile = new ZipFile(destPath, password.toCharArray());
for(String f: fileToZipPaths) {
zipFile.addFile(new File(f), getParameters());
}
}
private ZipParameters getParameters() {
ZipParameters zipParameters = new ZipParameters();
zipParameters.setCompressionMethod(CompressionMethod.DEFLATE);
zipParameters.setCompressionLevel(CompressionLevel.ULTRA);
zipParameters.setEncryptionMethod(EncryptionMethod.AES);
zipParameters.setAesKeyStrength(AesKeyStrength.KEY_STRENGTH_256);
zipParameters.setEncryptFiles(true);
zipParameters.setIncludeRootFolder(true);
return zipParameters;
}
}
And this code works. Archive is zipped with password.
The only problem with it is that anyone without knowing a password can open resulting zip file and see what files are inside. When You clicks on file it will require password from You.
But I wanna have files inside zip hidden with password. This can be achieved using any zip program.
I just don't know how to do this with zip4j. I've check docs:

but not find an answer.
Please help

由于专利问题，Zip4j不支持对文件列表进行加密。
参见：http://www.lingala.net/zip4j/forum/index.php?topic=104.0
更新：
如链接中所述，zip规范不包括对文件列表的加密。为了隐藏文件名，您可以创建一个包含您的文件的zip文件，然后再次对其进行压缩。因此，如果您打开zip2.zip，您只会看到"zip1.zip"，而不会看到原始文件名。
