Author Topic: Use public key cryptography. (Read 2118 times)

OK
High time JTFers started safeguarding their privacy and anonymity.
You have the right to lock your doors, you have the right to remain silent in police interviews, though G-d forbid anyone should go through that. Extend the same protection to your digital world.

A public key in case you don't know is a system where data is encrypted by what is called a public key but can only be decrypted by a npn-symmetrical corresponding private key. The public key can be made general knowledge - hence the term.
We use public key cryptography quite often without realising it. When you see the little padlock sign on https on sites like ebay, the channel has been secured by that sites public key, thats how they exchange data.
You can extend the benefits to email.
It would mean that once you encrypted data with the recipients public key, then only that recipient will be able to decrypt the data...
ever.
Would save me messing about with PMs and password swapping when I needed to send sensitive data.
Now there are two freeware bits of software that can facilitate this which I have been kind enough to provide links for. BCarchive for data and BCtextencoder.
They're easy to use and the BCtextencoder doesn't even need installing.
I have a public key so I can send messages to myself at the moment, which is useless. I've no one to play with. I need someone to play with. Do not begrudge the couple of minutes it will take to generate your keypair, the payoff will be tremendous.

OK, read the help file, make sure your key is at least 2048 bits, give your private key a strong password, at least twenty characters and put a number or symbol in somewhere where you can remember it.

If you forget the pass or lose the private key, then no one is decrypting data adressed to you...ever.

You can publish and send the public key anywhere you want, tho I recommend limiting distribution, so people know its from you and you do not send the private key (duh)

That is actually an expiring one I need to make a non expiring one.

You are talking about email ?

muman613 · « **Reply #2 on:** October 08, 2012, 03:59:45 PM »

For home use there is PGP (A commercial product I believe) or the open source version GPG {Gnu Privacy Guard}

Quote

The GNU Privacy Guard

GnuPG is the GNU project's complete and free implementation of the OpenPGP standard as defined by RFC4880 . GnuPG allows to encrypt and sign your data and communication, features a versatile key management system as well as access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. A wealth of frontend applications and libraries are available. Version 2 of GnuPG also provides support for S/MIME.

These Public Key encryption/decryption system is very secure {by industry standards} but it is believed that the supercomputers used by the government may be able to crack the keys. These keys can be used to sign and encrypt email communications, often integrated into the mail system through MIME. http://en.wikipedia.org/wiki/MIME...

Of course the encoder/decoder can be used to encrypt local files also. When dealing with a message from one GPG user to another the public keys are shared, so the message can be encrypted so only the intended recipient can decode it.

http://www.gnupg.org/

http://en.wikipedia.org/wiki/GNU_Privacy_Guard

I use this encryption on files which I want to keep private {such as my work source code}.

muman613 · « **Reply #3 on:** October 08, 2012, 04:03:32 PM »

I guess BritishSword is talking about alternative software to the PGP/GPG toolchain.

I find the existing tools adequate enough to do all my encryption. GPG is free and there are many tools which work with it.

I personally had to use pgp for a client once for email communication. He was extremely paranoid about corporate espionage, snooping, etc.

Zelhar · « **Reply #6 on:** October 08, 2012, 05:16:54 PM »

The problem is I can't force people to encrypt emails they send me, and I can't expect them to go through the trouble of decrypting the mails I send them. Except for this two little problems which render encrypted communication all but useless, gpg is awesome.

Muman, I don't know much about computers so I could be wrong, but wouldn't sharing your public key on the internet be a security issue?

The public key is used to encrypt data you want to send to muman, and it is meant to be distributed to everyone. The only way to decrypt the message is with the PRIVATE key which is secrete.

No, thats the beauty of PGP... the public key is supposed to be public... it can ONLY be used to scramble.. not to unscrable...

Only the private key is for unscrambling....

Its quite an ingenious concept and without it... secure communication would be much more difficult.

Public keys cannot be used to decrypt my encrypted files... Only files which I encrypt to be read by another users public key can be decrypted by the recipient..

Security quality

To the best of publicly available information, there is no known method which will allow a person or group to break PGP encryption by cryptographic or computational means. Indeed, in 1996, cryptographer Bruce Schneier characterized an early version as being "the closest you're likely to get to military-grade encryption."[1] Early versions of PGP have been found to have theoretical vulnerabilities and so current versions are recommended. In addition to protecting data in transit over a network, PGP encryption can also be used to protect data in long-term data storage such as disk files. These long-term storage options are also known as data at rest, i.e. data stored, not in transit.

The cryptographic security of PGP encryption depends on the assumption that the algorithms used are unbreakable by direct cryptanalysis with current equipment and techniques. For instance, in the original version, the RSA algorithm was used to encrypt session keys; RSA's security depends upon the one-way function nature of mathematical integer factoring.[2] Likewise, the symmetric key algorithm used in PGP version 2 was IDEA, which might, at some future time, be found to have a previously unsuspected cryptanalytic flaw. Specific instances of current PGP, or IDEA, insecurities—if they exist—are not publicly known. As current versions of PGP have added additional encryption algorithms, the degree of their cryptographic vulnerability varies with the algorithm used. In practice, each of the algorithms in current use is not publicly known to have cryptanalytic weaknesses.

New versions of PGP are released periodically and vulnerabilities are fixed by developers as they come to light. Any agency wanting to read PGP messages would probably use easier means than standard cryptanalysis, e.g. rubber-hose cryptanalysis or black-bag cryptanalysis i.e. installing some form of trojan horse or keystroke logging software/hardware on the target computer to capture encrypted keyrings and their passwords. The FBI has already used this attack against PGP[3][4] in its investigations. However, any such vulnerabilities apply not just to PGP, but to all encryption software.

In 2003, an incident involving seized Psion PDAs belonging to members of the Red Brigade indicated that neither the Italian police nor the FBI were able to decrypt PGP-encrypted files stored on them.[5]

A more recent incident in December 2006 (see United States v. Boucher) involving US customs agents and a seized laptop PC which allegedly contained child pornography indicates that US Government agencies find it "nearly impossible" to access PGP-encrypted files. Additionally, a judge ruling on the same case in November 2007 has stated that forcing the suspect to reveal his PGP passphrase would violate his Fifth Amendment rights i.e. a suspect's constitutional right not to incriminate himself.[6][7] The Fifth Amendment issue has been opened again as the case was appealed and the federal judge again ordered the defendant to provide the key.[8]

Evidence suggests that as of 2007, British police investigators are unable to break PGP,[9] so instead have resorted to using RIPA legislation to demand the passwords/keys. In November 2009 a British citizen was convicted under RIPA legislation and jailed for 9 months for refusing to provide police investigators with encryption keys to PGP-encrypted files.[10]

BCtext encoder is compatible with PGP public keys.
So thats fine if you already use gpg/pgp software no need to download what I put there.

The problem is I can't force people to encrypt emails they send me, and I can't expect them to go through the trouble of decrypting the mails I send them. Except for this two little problems which render encrypted communication all but useless, gpg is awesome.

Ahhh problem in chair not in computer.
Don't worry zelhar I'm a crypto fanatic you send me as many crypted things as you like I will go to the trouble of decrypting them. It will only take 2 seconds... I mean what trouble?

I'm not sure how you guys managed to post the text block of your public keys, I had to link to mine in certificate format, how did you do that?

-------
I also wasn't talking about just email. If something went wrong with the PM system for some reason we could post messages on the public board and still have them only be read by the intended recipient. How cool is that?

Also JTF is virtually hack proof - thanks shlomo.
But in the million to one chance that my account is compromised I could ensure that private messages stay private.

If you use linux you can export the key and save it in a text format. Either using command line or with a gui program like kgpg (KDE) or gnupg (gnome). The keys are by default given name like "my key.asc" but they are actually plain text files. Encrypted files are usually given a name like "name.ext.asc".
