alternate dos pgp client?
The latest release of Mixmaster claims to be an "OpenPGP enhancement release". I looked at the source more closely, and it seems to contain an entire pgp implementation. I had previously thought it made external calls to either pgp or gnupg. This got me thinking - has anyone tried hacking mixmaster to be a pgp client? I have compiled it under DOS before, so I know that is possible. Does anyone know if mixmaster can use 'non-legacy' RSA keys? Is there any pgp functionality that it lacks? I am looking for a pgp implementation that will run on DOS, but will also be compatible with modern key types.

It is possible to build a simple PGP client with the source you have -- the file pgptest.c offers that, but it's really only for debugging purposes. Run "make mpgp" in the Src directory to try it. A better interface to the standalone PGP functions shouldn't be hard to write. We can look into that if there is demand for it. Note that Mixmaster has no concept of the web of trust, and doesn't do keychain management. It assumes that if you are placing a key on your keyring, you've determined it is valid. That said, Mixmaster does offer all the basic OpenPGP messaging capabilities, except for verification of clear-signed messages. (This wasn't needed for any of the features Mixmaster provides, so it wasn't added.) We'll be adding this capability soon, however. (The author of the QuickSilver Windows remailer client app has requested it. QuickSilver provides PGP capabilities through the Mixmaster .dll, sans clearsig verification.) Mixmaster does support RSA v4 keys, though it doesn't have Twofish support since it links against OpenSSL for its crypto, and OpenSSL doesn't have Twofish support. If you have OpenSSL 0.9.7, Mixmaster will support AES. (Also, Mixmaster now supports use of the Modification Code Detection packet in OpenPGP messages, which is used to prevent the attack Schneier, et al. recently wrote about.) As far as DOS goes -- I honestly haven't tried compiling for DOS. It "should" work. Please let me know if you run into any problems. (And, as always, we're in need of developers and testers. If you're interested in working on this project, please join the development mailing list. See mixmaster.sf.net for more info.) --Len.
From what I've seen mix3 (pgptest app) is the closest to providing a command line. There was also Tom Zerucha's reference openPGP code, which is command line but it's alpha level code I think and no longer
I put together a list of openpgp related software at: http://www.cypherspace.org/openpgp/ this includes library only code, and add on software. Not sure about your questions about key versions, but I forwarded it to Ulf Moeller and Len Sassaman (current maintainer of mix3). maintained.
