  1. Re:I don't use it for the encryption on Do Slashdotters Encrypt Their Email? · · Score: 1

    if you sign and encrypt emails, you don't have to verify the keys, that's done automatically:

    John Smith wants to send Jane Doe an email, so he looks up her public key at an online key repositoy.

    He uses her public key to encrypt the email and his private key to sign it.

    She receives the email and decrypts it with her private key, validating his signature using John's public key she looked up in the key repository. If her public key (used by John to encrypt the email) had been spoofed in the repository, she wouldn't be able to decrypt the email with her private key.

    You're almost right, but you're wrong about the lack of need for verification. The fact that she can decrypt the email which was encrypted with her public key obtained from a keyserver simply means she is in possession of the corresponding private key, not that she really is [the right] "Jane Doe" ... you might be beginning a correspondence with a spook. To verify that she is the person she is supposed to be (and not some Black Ops team MITM'ing her), the public keys must be verified, either by exchanging them in person in the first place, or by reading out key fingerprints over the phone if you would recognise her voice.

    If John and Jane both get each other's public keys from a repository, and fail to verify them, then both keys may be bogus keys uploaded by MITM Bad Guys. This was well described by Phil Zimmerman in the original PGP 2.x User Manual

    This is the other part of the PGP web-of-trust concept that most geeks I know don't quite get. When I countersign your key, I'm signing it to say that you really are the person you say you are (or rather "this key really does belong to the person it claims to belong to"), and NOT you are a person who can be trusted. So I must NOT countersign your key unless/until I'm really sure it's your key - which needs the key verification step to have been performed.

    Unfortunately, most IT people I know who've ever been persuaded to try PGP just merrily get busy countersigning all the public keys they acquire, whether or not they've verified them. It doesn't help that some PGP email client software insists that you only use 3rd party public keys you're certain of, and won't let you pick an unverified key - so users will often just sign the 3rd party key to say they're certain of it so they can click 'Send' on the email.

    Relatedly, I often suspect my colleagues don't even read the question you get asked when signing a key, which says "How strongly do you believe this person knows how to use PGP properly ?"

    It is actually quite tricky to use PGP carefully enough to gain the full web-of-trust benefit - although I agree you can do what many folks do, and just ignore all that key-signing stuff, and wing it :)

    Sigh ...

  2. Re:Perfect american corporate business practice on Cnet Apologizes For Nmap Adware Mess · · Score: 1

    I tend to look at your statement as part of a big problem with Americans. You can rationalize any number of clearly unethical or immoral situations by either stating, "...it's not illegal..." or "...XXXXXX does the same thing

    It's not specifically Americans - it's capitalism (or "unhealthy love of money"). The problem with Americans (generalising like mad here of course) is that they sure do like the ostensible benefits of capitalism, and often fail to see the consequent drawbacks, but the same problem affects (infects) many other western countries these days.

    I remember years ago watching an interview with the chairman of Rio Tinto Zinc (RTZ), in which he was being given a hard time about how RTZ was digging up aboriginal sacred burial grounds to look for uranium. His reply, with an apparently straight face, was "What we are doing is not illegal, and as chairman my responsibility is to my shareholders to deliver the maximum profit possible".

    He simply couldn't see the immorality (or at least amorality) of the company's actions - or if he could then he simply didn't care, so long as the profit was good

    Capitalism doesn't do morality - it just does money. Transcending this is an evolutionary step that must be made if humanity is to have any future.

  7. Re:I didn't know it was shareware. on Trumpet Winsock Creator Made Little Money · · Score: 1

    As I recall, early versions of Trumpet Winsock (2.x ?) were a bit scrappy in look'n'feel and offered just a SLIP connection over a serial port, while later versions (3.x ?) were considerably smartened up and widened the protocol choice to include a rather nice implementation of PPP. The arrival of this PPP improved the ballgame no end. I think it even had a useful tracing facility.

    To complement this Trumpet also sported a capable dialer with a scripting "language", and a few sample scripts for different scenarios. Usually, you scraped online using a cobbled version of one of the samples, and then if you hunted around online you could find more comprehensive pre-written scripts tailored for the various well-known ISPs.

    To my shame I confess I never registered any version of Trumpet, though I subsequently did register a few other shareware items ... WinPost PostIt notes, Bloat filesystem manager, Novagraph Chartist, and WinQVT VT220 emulator - all Win3.1 apps .... ah, happy days :-)

This is really important for security-related software distribution sites where it's necessary to be absolutely sure where your downloads are coming from.

    The site does however have some problems with organisation of content - e.g. it'd be nice if they followed some more de-facto site-structure conventions like having a "Downloads" link to a page which provides the source tarballs, and states explicitly that there are no binaries available ... and maybe even provides links to the more common Linux distro repositories where binaries may be found, even places where (gasp) Windows binaries can be found .... like http://www.stunnel.org/download/binaries.html (the place I always used to go to get my Windows OpenSSL binaries, but which seems a little unmaintained these days) .... or http://www.slproweb.com/products/Win32OpenSSL.html (which is a lot more up to date, and professionally organised).

    There is an openssl.org page with info about Win32 binaries :
    http://www.openssl.org/related/binaries.html
    (which links to the www.slproweb.com site) but it's not easy to find (IMHO).

    And then there's the awful documentation, as many others have mentioned. I'd offer to help out with that if I was half-way crypto-competent enough to do so.

    Hahahahahahahahahahaaaaaaa .... "advanced technology" ?

    We were doing this in 1980 with the ICL VME mainframe operating system using their proprietary comms protocol "ICLC03", which prioritised traffic according to which of 6 different categories the relevant device was defined to be in. That's how we could support a cluster of 16 dumb terminals and half a dozen printers down one 9.6Kbps line without all the terminals stopping dead every time somebody printed something.

    I hardly think the technique can be described as "advanced" ... "common sense" maybe. I've always wondered why TCP-IP doesn't include such a feature.
