      In Canada it can get jiggy with other encryption technology as long as it isn't >5years senior (and was able to last year as well). It'll have to wait until 16 to consent for any age and 18 if it is interested in encryption with influential power over them. I'm not sure if there are laws about related algorithms. In my neck of the woods we don't code that way.

I was in a long distance relationship in college at the time, and my girlfriend had a mac (I had a PC). PGPfone was the only VOIP solution in 1999 that allowed us to voice chat for free (remember, this is before unlimited minute cell phones). Absolutely amazing as a voice chat program, let alone all its privacy features.

        ZFone [zfoneproject.com] (Windows, Linux, MacOSX) uses ZRTP and can work with any SIP-based software (because it intercepts and encrypts the stream).

      I think you're confusing a few things.

      Web of Trust (WoT) is a PKI model. Certificate Authorities (CA) is a competing PKI model, and the one apparently you prefer. Have you taken a look at the CA list of trust in your browser lately? I for one prefer WoT, although more work on the part of the user to maintain, the trust model is based on me, not "Staat de Nederlanden" or any other company I've never heard of. Not to mention the stolen Microsoft certificates of a few years ago. There is nothing to stop us from moving to a WoT model for our browser PKI, just as there is nothing stopping us from using the CA model for email, it's just how it's been implemented for us thus far, and which we choose to use.

      MIME vs Inline are competing ways of using PKI in email, it appears you prefer MIME which does appear to be the merging standard.
      • Nope, I'm not confused. You're pedantic.

        It doesn't matter what you prefer. It will WoT will NEVER catch on. S/MIME will catch on as more organizations adopt it internally. Soon people will want to do at home what they do at work, and companies like Thawte will let them do so. Once gmail or hotmail start allowing "verified" (signed) mail to premium users, the rest will be history.

      And it has not killed the PGP market or even gotten major traction. What percentage of your legitimate incoming email is S/MIME signed? Even from your bank?

      Also, bear in mind that CA-based PKI is a strict subset of web of trust.

      The lesson is that crypto goes nowhere in the market unless it's as transparent as TLS.

It needs to be as easy as hitting send on an email, automatically sign it, and if the recipient is known to have a key then encrypt it to them.

    Jeez, will this fairy tail never end? Phil NEVER released PGP. Crap, I was there and I remember it. Phil had to be browbeaten and bribed to give up the software (for which he had already been paid to develop).

    There were two people who were hauled up in front of the Federal Grand Jury. Phil was one. Kelly Goen was the other. It was Kelly who paid Phil, who researched the law (so that the release could be done legally) and who had been pushing for developing public key cryptography for years before he ever met Phil. And it was Kelly who had the guts to do the actual release. Phil thought he was completely safe at the time (and legally speaking he probably was, not that innocence has ever stopped the Feds before).

    If you want to search, you might be able to find the original Jim Warren articles in Microtimes around, who Kelly kept in touch with during the actual release. Jim thought Kelly was paranoid as hell until the FBI showed up on his door, and he wrote at least one article about it.

    For your amusement, Kelly went around the San Francisco Bay area with an old acoustic coupler modem to various pay phones and would upload it onto a different server. Then he'd call Jim to tell him where it was at, in case something happened to him. He was under the impression that the single best thing the NSA could do was to knock him off before he put it on those servers. Looking back at it now, he was quite right.

    And no, this isn't being posted by Kelly. Just someone else who was there at the time.

    So please, get your facts straight and give Kelly some credit while he's still alive. Thanks.
  • and still almost nobody uses it. There's a real trade off between security and convince. How many people do you think would use SSL if they had to download a separate program beyond the web browser and setup certificates to support it? Probably about 10% of the general internet population, and those would be the ones who realized their credit card numbers weren't be passed encrypted. General rule of thumb.. If it's not (relatively) easy for the end user it will never become popular.

      I used it 63,000+ times last month alone (automated of course). While PGP may not be very popular for the individual user, it is commonly used in the corporate world.

  • a good thing Larry David was busy on other projects (and isn't a famous cryptographer on the side) otherwise the project may have been dubbed PPPPPPPGP, with the first couple of Ps in italics, probably. [youtube.com]

  • I remember watching an English documentary about 5 or so years ago on the history of encryption and cyphers. One thing I remember was how the RSA public and private key encryption wasn't invented by PGP even though they were awarded a patent , it was invented by an english researcher while working for one of the many U.K government secret service shadow projects at the time. The UK security services have been using RSA encryption for many years before PGP ever figured it out but wouldn't admit to this fact

      you are confusing the peope behind RSA (Ron Rivest, Adi Shamir, and Leonard Adleman) with PGP. Phil Z did not invent any algorithms (well, except for Bass-O-Matic). He just was the first to make an implementation that became publicly available.
    • RSA has(had) the patent on RSA public key encryption. PGP was just the first to popularize it, and make it easy for people to use it. And, in fact, not having the patent (on both RSA PK and also IDEA symmetric) is what caused PGP to later switch to ElGamal and 3DES, so that those are now part of the OpenPGP standard whereas RSA and IDEA are deprecated and fading into disuse, despite the fact that the RSA patent finally expired.

    • by jlockard (140979)
      Nope, RSA Security was awarded the patent. PGP implemented RSA in their code (as well as Diffie-Hellman (DH), but had no hand in developing the encryption. Also the UK security services used something similar to RSA, basically the same idea, different implementation, but could probably have been covered under the same patent language.
  • PGP suffers because of remarkably poor nomenclature. The terms "public key" and "key pair" lend less than zero towards understanding the simple concept of how these objects are involved with encrypting and decrypting messages.

    I've supported applications that use PGP for almost 9 years, and the number of times I must explain and re-explain how PGP keys work is just sad. In fact, there is one PGP administrator who methodically signs and distributes, every month, his company's latest public key *and* key pai
    • When signing, in fact, the exact opposite happens.

      Public and private isn't too bad, it's just that no one ever, EVER bothers to learn them. I mean, come on, if people can learn words like "clutch", "gearshift", "ignition", and so on, why can't they understand that the PUBLIC key is what you send to everyone, and the PRIVATE key is what you don't even share with your lover?
      • oh, share it with your lover. just don't WRITE it on her. people may see what's written on your hand and throw off your whole privacy scheme.

      "Why, oh why, didn't Phil just call them "encoders" and "decoders?"

      Would that be because the "encoder" used for encryption is the "decoder" used for signing?
  • Maybe it should be noted in this context that GnuPG 2 has been released [gnupg.org] recently. No longer a monolithic application, it includes tools for key and passphrase caching, smart card support, configuration, certificate revocation list and LDAP support and more. Thanks to Werner Koch et al for keeping developing this valuable tool.
  • ...would be to say "My e-mail server, my key server". Use SSL certs or whatever to verify that you're talking to a legitimate server, and a way to connect securely to request a key is a must. I presume it's quite feasible to verify that you're talking to a legitimiate @domain.com server when trying to get the public key for a @domain.com address. So if I have a yahoo.com address, you can ask SMTP server "PUBK name@yahoo.com" and get either "no keys, sorry" or "uploaded key follows". Your email client should

    In the early 90s i spent (way too much of) my energy in the marijuana movement. Not wholly surprisingly, i got a little paranoid about marajuana-movement organizations' mailing lists being confiscated in various busts around the country.

    So i relentlessly harangued a national organization to distribute a windows/DOS/Mac PGP release to all of their chapters.

    I felt pretty good about it until i got a call from someone in another state:

            "duuuude. i forgot my passphrase..."

    How did you do that?

              "we were rilly baked ..."

    i've always wondered how much damage i did to the marijuana movement by handing a bunch of stoners a tool that required memorizing a passphrase...

    my bad!

      In the 70s, I smoked a lot of dope. Because it was fun.

      Please just accept that, like me, you did it because it was a great way of getting wasted with a few friends for a few hours - just stop with the "political justifications", okay?

    Everyone here is talking about PGP encrypted mail.

    I know there's problems with security legislation in the USA, and it's patented/restricted somehow. I would use gnupg for email if I had anyone to use it with. I only come across it in signed software.

    Do you think signed/encrypted mail has a part to play in the new email? Email as we have it is WANK, with all the spam and shit. Something needs to be done. Perhaps a system could really on signing email with a unique key from a sender. Then there's an delocali
