Hi, Can someone please tell me the status of Zip64 support in commons:compress? I read that it was supposed to go into 1.1, but I don't know how to tell. Thanks - Chris - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org

compress - 3 questions about encryption
Hi,
I hope someone can advise me.
I am developing Java code to handle archives using commons compress and am
currently focusing on ZIP files. I understand that ZIPs can be encrypted in
two ways:
(a) the contained entries can be plain text or encrypted
(b) the whole ZIP itself can be encrypted
QUESTION 1: Is this correct?
If so, I need to be able to detect both. So far I only know how to handle (a),
by using this method:
public boolean checkZipEntryIsEncrypted(ZipArchiveEntry entry) {
boolean encrypted = false;
// Check if zip file is encrypted
if (zfile != null) {
if (! zfile.canReadEntryData(entry)) {
encrypted = true;
}
}
return encrypted;
}
QUESTION 2: is this the right way to detect encrypted entries?
QUESTION 3: what is the right way to detect that the ZIP itself is encrypted?
Thanks,
- Chris
