Re: [Enigmail] Using Enigmail for mailing lists
-BEGIN PGP SIGNED MESSAGE- Hash: RIPEMD160 Hi Boris, me and some friends of mine want to exchange encrypted emails on our mailing list. Does enigmail support encryption for multiple recepients? How would you encrypt information on a mailing list? I know of three ways to achieve this: either request anyone joining to provide his/her key to the list master who in turn merges all received keys in some keyring that is redistributed to all members - or by using one shared key. In general, both only work with smaller groups. In the first case, all members need to regularly redownload the current list-public-keyring and adopt their per-receipint rules. In the latter case, you need to trust each member to redistribute the key (and not being haked). In your case it seems to be a smaller group. *If* all members have the ability to define rules such as Enigmail can, there is a third way: you import the pub keys of all members and define a per-receipient rule Encrypt all messages to list-address to the following keys: member1, member2, That works well at least for our internal Enigmail team list address ;-) Olav - -- The Enigmail Project - OpenPGP Email Security For Mozilla Applications -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.22 (MingW32) Comment: Dies ist eine elektronische Signatur - http://www.enigmail.net/ iQGcBAEBAwAGBQJTJcl3AAoJEKGX32tq4e9WrY0L/i5nEUGh/CTlgPP0ZB04Oq+a qKQV09P+ZyNO3kTEdhxk+RIj3shuX4oCunrCQR24kC2U2KDs3TGGhJ+86WU8R5D+ Fcw9/1jbLuCQMwD4aXRceo7wd7gwPMtX4B5scSpfYjZGgT/s71cCPeGQCyLyrdBD eoexvIJQvW5iLDpaoIBFrZJhv9xAMq+Kg2qGD/yt3aUcj+drVpN3ySpJcLE5J4iA uA5Zb3Q2clmgRTHiXlKRrvKFyMrUZCRZo4CH+fXr6oPTtgy/Sbq8GPcyujrvF86e UybC0GWLoWBDW5O5jFxve0Fxiqp2iiodpm9lcrt94kJHB6r70sgX+todJsF169yp nreZVTHIU5Qw3RW71l/l0ooHd3T8eL6oeCT5J5HVU8ZNnPGRsC4rYP3dOaqiZvxN X+Cc5NIXXTeB2VD0j+nXjYCpyYpMCO+N7sMHmbjgDVx4qaGPyaCKFTUk34AlsXWu WbXD8+suOxF/NJmZcp+7enbUvw6umZpjheq7SdkY6A== =Lwpa -END PGP SIGNATURE- ___ enigmail-users mailing list enigmail-users@enigmail.net https://admin.hostpoint.ch/mailman/listinfo/enigmail-users_enigmail.net

Re: [Enigmail] What about PGP/Header support?
Oh, I most definitely can send an encrypted message to anyone. The recipient will not be able to decrypt it since I don't have his public key so I'll have to use some random other key, but I can send him an encrypted message. Anyway, these things confirm my point: the way the PGP signature is transfered is only relevant for signed but unencrypted mails as you may as well send these mails to people that do know know, understand or use PGP. And those people may get confused by the way that the signature is transfered: either inline or as an attachment. Embedding this in the header solves this issue. Of course, it will require further specification in an RFC and it will require more broad support than from just one client (although I personally don't know anyone that does use PGP and does not use Enigmail to do so but that's just my personal circle, of course). But it has to start somewhere, right?
