Ciphire, A Transparent, Easy PGP Alternative

mixter writes "Hi. I'd like to point your attention to Ciphire, a fully free and soon-to-be-audited-OpenSource 'Global PKI' project I've been working on for the last three years. As the first three or four thousand geeks started using Ciphire and seem happy, with some tech articles written, I guess the /. community might find this interesting, too. Ciphire hopes to have solved the problems that prevented PGP from a broader deployment, with even higher security standards - as already confirmed by crypto experts Housley & Ferguson. More useful information, e.g. in Wired or in the Nerd^H^H^H^Hexperts FAQ."

      Its actually pretty simple. I figured it out just reading the "automatically" but I'll break it down for you. Directly from their website:

      "The Ciphire Mail client resides on the user's computer between the email client and the email server, intercepting, encrypting, decrypting, signing, and authenticating email communication. During normal operation, all operations are performed in the background, making it very easy to use even for non-technical users."

      I shouldn't have to explain it any further than that here on Slashdot. Thats in the first paragraph of the Technical Explanation of how it works. Later on it lists:

      "The Ciphire Mail client consists of three parts: the core client, a graphical configuration interface, and mail connector modules (redirector). Supported email protocols include SMTP, POP3, and IMAP4. The STARTTLS and direct SSL/TLS variants of these protocols are supported as well."

      For anyone that didn't get the gist - it basically redirects your mail to its own "server process" sitting on your computer then sends it out to the normal SMTP server. This is using the same technology that the current Mail virus scanners use (Think Symantec), not new technology, just used in a different way.

      On the reverse end, the "server" checks the mail and hands it to the email client making everything secure in between.

      Pretty simple way of getting Jane and Jon Doe with OE to use it if you ask me. Granted, it needs to be installed by Admin on proper machines, but that shouldn't be too much of an issue for any company that would like to secure their email - especially if you explain and show your network admins that email is USUALLY a plain text security nightmare.

Apparently email client plugin interfaces are nonstandard, change with each release, and all too often buggy. The default advice to people running PGP with their mail client evolved into "use the Encrypt Current Window function", which sacrificed integration between key selection and email addressing.

      If I understood what the developers said, they wanted to do PGP Universal because they couldn't stand the plugin hassles. PGP Universal and Ciphire may signal a trend toward putting the crypto downstream of the email program.

  20. Centralized directories are bad ! by louarnkoz · · Score: 5, Insightful
    If you look at the little pictues "how it works" on the ciphire site, it appears that before sending a mail to Bob, Alice retrieves Bob's certificate from the ciphire central server. Really? And that is private e-mail? They must be kidding!

    What do you think will happen if someone, say in the name of the war on drugs, wants to interfere? Presto, they can convince the central server to yank Bob's key from the directory and replace it by one of their choosing. Some privacy!

  22. Web of trust needs plane tickets by tepples · · Score: 2, Insightful

    just buy a certificate to make Ciphire work.

    The OpenPGP equivalent to a certificate is called a "plane ticket" whose price is called "airfare." Without a plane ticket, you often can't get your public key signed by people in the strongly connected web of trust. Without a signed public key, you can't build the web of trust, and without the web of trust, you can't verify a public key, which is the whole point of certificates.

  23. Ciphire compared to PGP and S/MIME by davids-world.com · · Score: 2, Informative
    I've posted a high-level overview and commentary a couple of days ago.

    The verdict: Ciphire is a good idea in general and a fine solution for internal security in companies (across different sites), but difficult to justify as a standard due to its closed nature.

  24. Re:S/MIME, anyone? by davids-world.com · · Score: 2, Interesting

    For S/MIME, you'll need to retrieve the recipients public key (i.e. certificate) first, which you usually to by receiving a signed e-mail from that person. From then on, everything is easy and, honestly, more conventient than using a GPG plugin with your mail client, because mail clients support S/MIME natively.

    Generating and installing your own certificate is, well, not complicated, but too much hassle for a naive user. You have to find the right function on thawte's website, enter all sorts of personal data, add and confirm your e-mail addresses, request a key and pick the right certificate type, and so on.

    And in my experience, this is somewhat difficult to do on Windows for non-techie users. It's easier on the Mac, as usual. So that's where Ciphire is so much easier.

    Yeah, maybe someone should come up with a webmail client that seamlessly incorporates SSL and PGP crypto--oh, wait, it's been done.

  26. Careful: not very secure, not very trustworthy by mikep.maine · · Score: 2, Insightful
    I have serious reservations about Ciphire. Seems more marketing than real science. I'll bet anyone of drinking age a beer that this doesn't becomes open source in 2005.

    What concerns me are comments like the following: "Each Ciphire certificate is reduced to a hash, an abbreviated mathematical identifier. Since the relationship between the hash and the certificate is reciprocal, the original hash would not match a certificate in which there was even the slightest change."

    Not so fast: (a) certificates already have a signed hash; (b) it is common practice to state which hashing algorithm is used (SHA, MD5, ...?). I hope its not homegrown hash; and (c) by definition, hash values have collision where more than one certificate can map to the same hash value.

    Just cause its an open-source wannabe doesn't mean its good for you. Let's hope for the best.

  27. Support for triple-DES should be added! by Eric+Smith · · Score: 2, Insightful

    Some experts think that since DES has withstood so many years of scrutiny, and there still no atack significantly better than brute force, that triple-DES may be a better choice than AES, Twofish, and Serpent, none of which have yet been subject to a comparable amount of cryptanalysis. Yet triple-DES isn't in the list on the ciphers page. Why not?
