Re: best pgp software question
I think this thread got off from the original topic, as practically speaking
gnupg or PGP will do what the poster wants. I most cases, if people
intercepting data see that it is encrypted and they have strong reason to find
out what the content of the data is, there are usually cheaper and easier ways
to go about getting it than trying to decrypt it.
I asked one of my professors who is an expert mathematician and cryptologist,
about this issue once, and he said that most of the ways organizations like the
NSA get to your data is through implementation flaws (OS, encrypting program,
key-loggers, encoding methods) not through algorithm flaws. He also said he
thought it VERY unlikely the NSA could, in a reasonable time frame,
"brute-force" a 256-bit symmetric key like AES.
If we assume the computer system itself, encryption implementation, and encoding
methods are secure (the biggest pitfall), and we assume there are no known ways
better than brute-force to crack a symmetric cipher like AES, a 256 bit key
would mean, on average, a search through 2^255 key permutations. While no one
(outside the government) knows the NSA's capabilities, assume they can try
1,000,000,000,000,000 (one quadrillion) keys a second, the average time needed
to find the key would be 1.83*e^54 years. The universe is estimated to be about
20 billion years old. I've heard based on our understanding of particle
physics, there is not enough energy in the known universe to run these kind of
calculations.
So if done absolutely right, the encryption itself is solid. It's everything
around it that usually breaks down.

Sure, if they were after you, that's true. I don't have anything
illegal to hide. Some people, like me, believe law-abiding citizens
have the right to some privacy. Even if it's nothing special, I want
the right to keep it private from anyone. The NSA wants to see
everything, not matter what it is. They want to destroy privacy.

Even in George Orwell's 1984, there seemed to be places to hide from

Suppose you do this: erase a hard drive, install the OS, then install
PGP, that guards against spyware.

Source code isn't a guarantee that a program has no back doors, nor is it
the only way to find them if they exist. It's certainly helpful, but I'd
sooner trust a closed source application using standard algorithms offered
by a reputable author than an open source implementation of an untested
algorithm devised by some guy who calls himself "Mr. Krypto". ;)
If you fear back doors, you need to fear them in all applications. Even
more pressing is the issue of simple mistakes. They're both threats to
your security that have from time to time "magically appeared" in crypto
software of both open and closed source varieties. If your data relies on
a dire need for absolute cryptographic security, you're completely out of
luck. What you need to be considering is a strong dose of physical
security, maybe with a crypto chaser.
[color=blue][color=green]

> Ok. So why don't you feel fear?[/color]
Two reasons:
1. My data isn't so important that I have to worry about the NSA or the
FBI dorking around with it. The threats I see on the horizon are
incompetent wannabes like the guy who tries to steal my laptop and finds
out all my vital information is in an encrypted container. I'm confident
my passwords and scanned images of official documents are safe from that
sort of attack.
2. I'm fully aware of the risks and benefits of encryption, and have a lot
of trouble feeling fear for anything I understand. Fear is generally
something you feel either because you see an imminent threat, which I
don't, or a result of facing the unknown.
If I WAS afraid in any way that I might fall victim to some sort of back
door, then I would certainly take additional steps to make sure my data
was removed from any possibility of compromise. Like a secret panel in
the back of a closet with an electrified door leading to a hardened bunker
guarded by packs of rabid Rottweilers. Something like that. ;-)

Usually. If you don't place too much faith in it, it's fine. It's
something to consider when choosing security applications, especially so
when examining what algorithms are used. All other things being equal it's
more prudent to choose open source crypto over closed source, but it's not
the sole deciding factor. If you place too much faith in open source, you
run the risk of making a bad decision because of that ill placed faith.

Then you'll be more than protected if you simply stick with any time
tested crypto application offered by a reputable company. Closed source or
otherwise. You're hiding stuff from associates and the occasional crook,
not the super secret crypto cracking division of some joint NSA/FBI task
force on Jennifer's evil data. :)
The majority of the more widely respected crypto programs happen to be
open source, and for good reasons, but at our mere mortal levels it's more
of a matter of personal comfort than any real threat of compromise.

Ahhh but therein lies the rub. They were unaware of YOURS until you went
and spilled the beans here in Usenetland. Now your cave is useless, and
you've learned the most valuable crypto lesson you ever will. Unless
there's some fatal flaw in your crypto, which nothing can guarantee
doesn't exist, it's you the user who is by FAR the weakest link. Crypto of
the modestly good sort used effectively is a LOT more secure than the
worlds best crypto used sloppily.

If all you want is to create an area is secure, where you can place
your documents and feel reasonably sure (given a strong password) that
they are safe from the eyes of others, then yes it is.
I'm just going to give you Truecrypt's advantages. Do some homework on
the PGP.
The advantages, to me, are Truecrypt's simplicity of operation and the
methods they used to craft the security.
They are using LRW mode for disk encryption'
[url]http://www.truecrypt.org/user-guide/?s=modes-of-operation[/url]
Truecrypt provides source code so it can be scrutinized and
re-compiled by all.
They provide for plausible deniability by construction of their disk
volumes which are not distinguishable from random data.
You can easily change your password if you want and not lose any of
the data.
It works under Windows and Linux.
It is free of charge and the people that write it are very serious
about what they are doing.
[snip known history][color=blue]

>In your opinion, should passwords be longer than 16 characters?
>[/color]
What you are looking for is entropy, which is a 5 dollar word for
randomness.
If you are going to use every available character from 00-FF Hex in
completely random fashion then 16 characters is really good.
That would give you close to 128-bit entropy.
But you wont be doing that, so you'll need a way to stretch out your
passphrase into something that contains enough entropy, but that you
can enter on a keyboard and remember.

You can start with the link above if you really want to know about

No, It isn't.

No, that is the way we move away from freedom. Privacy and anonymity
are the roots of all freedom.
While they systematically remove the checks and balances and ignore laws
as not relevant to them, they chant "If you have nothing to hide you
have nothing to fear" and "only criminals have something to hide". It's
the mantra of the day.
I reply to that: "If _you_ have nothing to hide then you should have
nothing to fear from proper judicial oversight". Yet, they keep working
to remove it. Well, it's not me that is hiding here and if their words
of "only criminals have something to hide" have any truth, why are they
hiding from proper oversight?

Security-wise, it's probably equivalent to PGP. I prefer it because
it's independent of PGP. I once used PGP Disk and when I updated my
version of PGP, my PGP disk was no longer accessible. I had to
uninstall PGP and re-install the older PGP to recover the data.
Since then, PGP has improved the effects of updating, but it still
left a bad taste in my mouth...

Obviously the longer the better. That's why they're now called
"passphrases" instead of "passwords". Truecrypt also has option of a
"key file" where you can point it to a file on your disk and it will
use the contents of that file to generate the crypto key. The file
better not change, though.

Let's hope that some catastrophe, natural or manmade, will clean out the
excess and get the world population down to something reasonable. One
billion sounds like a nice round number, giving the world plenty of people
to keep the high-tech stuff going, while giving everyone lots of room.
No one will give a damn then about IDs and what's going on in the Middle
East, or the rest of the insane stuff we live with today.
I say the sooner the better.

I prefer it to PGP because it has more options (algos). It doesn't require
installation* and has nice little features such as key files and hidden
volumes. It is also a very stable application. It has never failed me.

Depends on what its for. I tend to never use less than 15 characters for
passwords unless the system doesn't support passwords of that length.
Normally I have 8-10 words as my passphrase so around 50 characters total.
For a Windows password there are a lot of advantages to using >14
characters, one of the biggest being that it stops the LM hash being stored.

for more information.
For PGP I never use a password, only a passphrase.
* Administrator access is needed to the system to run in "traveller" (not
installed) mode. If you install TrueCrypt it is then possible for a non
admin (power user) to use TrueCrypt however I could be wrong on this, its
been a while since I checked.

My news server has not retained prior posts in this thread, but this
appears to be in relation to TrueCrypt. Based on this assumption, I can't
resist stating that PGP's Virtual Disk now defaults to using 256 bit AES
for the symmetric algorithm. Recent versions also have options of 128 bit
CAST and 256 bit Twofish. Personally, I just can't think of a reason why
including additional algorithms serves any real purpose in increasing
security. I don't recall the details now, and whether this was related to
either TrueCrypt or an ancestor of it, but I have seen at least one other
such product that included multiple symmetric options, with some being very
secure, and with at least one such option being quite weak.

Hi Tom. Yes the post was regarding TrueCrypt.
I guess it is more for performance than for security (although TrueCrypt
also allows for two and three level encryption with different algorithms
such as AES-Twofish-Serpent, I do not know mathmatically what extra
protection this gives you thought.
The biggest reason I prefer TrueCrypt over PGPdisk is portability (no
install need, no license problems) and its features such as hidden volumes
and being able to use a raw device (such as an external HDD).
While PGPdisk is very nice, the fact it is only available as part of the PGP
suite makes it difficult to use on a mobile device unless you purchase
multiple licenses. A stand alone version of PGPdisk for $50 or so would be
great IMHO.

At present, I mainly use GnuPG to sign files, so I have a way of
checking later to see if the file was modified since it was signed. I
will also be using GnuPG in tandem with Gizmo and Zfone for VOIP in the
near future. For encrypting individual files or collections of files,
however, I strongly recommend you consider using truecrypt. All of the
softwares I have named here are $-free, open-source projects that
support both Linux and WindowsXP. (I don't have WindowsXP on my
computer.) I also think it is smart to use an on-screen keyboard any
time you have to type in a GnuPG or a truecrypt password.

Oops. I misspoke. Zfone does *not* require GnuPG or anything like it:
Zfone uses a new VoIP encryption protocol called ZRTP to secure Internet
telephone calls. The protocol provides a high level of security because
it doesn't rely on public key infrastructure (PKI), key certification,
trust models or certificate authorities. *** ZRTP does the key
agreement process on a peer-to-peer basis, using a new key for each
telephone call.***
[from [url]http://www.voip-news-net.com/2006/05/zfone_for_windo.html][/url]
And Gizmo has nothing to do with encryption, it's just handles the VOIP.
