Protecting zip files

First, I wish all at the 'CNET' a very happy and prosperous New Year 2005.
Now my question is that how much security can one expect out of a password protected zip archive?
Isn't their any tool that can crack password of an encrypted zip file?
And again, what should be the minimal number of characters to be used to protect a zip file to the utmost extent?

Almost none. Here's why...

Look at

You can unlock it if you want. Still PDG (pretty darn good) for most things.

You didn't tell how secure must this be?

How to protect?

Thanks Mr. Bob.
Contrary to your opinion I thought that adding a password would give an adequate protection to a file, at least from the hands of a trespasser or hackers.
However, if the passwords can be recovered so easyly, how one should protect his/her files? I am talking about maximum protection for an average user.

Not my opinion here.

In reply to: How to protect?

I offered the noted link as proof how weak this password is. Also I noted that even as weak as it is, it is sufficiently strong enough for casual users.

However, if I can email, ftp said file off your machine then I can work on it elsewhere. You have to pick your level of security to see where you want to be.

The best security is to not let strangers on your machine. Hackers of any good skill level will walk right past a zip password.

Why let them on your machine?

What about sending an email-attachment?

In reply to: Not my opinion here.

Well, I understand your words. But it's not the question of letting others using ones computer. People often attach encrypted zip files with their emails but it is often said that emails are not so secured!

Such is very true.

It's why such software a PGP evolved. Look up PGP on

You may or may not remember that encryption laws were and are still a hot topic...

Will search about PGP

Thank you Bob. I'll search about PGP later. Meanwhie, can you tell me something about '160 bit Sha 1 key' encryption? I use 'ultimate zip'(it comes free) and it says it uses the above encryption method.

Not good enough.

Well.....parting now....

In reply to: Not good enough.

Thanks a lot.
I feel too insecure to continue (joking)!
So, I'm parting....Thank you once again.
