I think this feature would be possible and I think Jeremy mentioned it in a hangout [1]. The link is just a hint, since I didn't watch the whole stuff :) [1] https://www.youtube.com/watch?feature=player_detailpage&v=2UHjmJ1n5Xc#t=3076 > 2) Encrypted tiddlers could be decrypted with a "masterpassword" too.. > (here introducing the idea of having two layers of passwords...) > I think, with the existing mechanism this isn't possible, to handle in a convenient way. The mechanism, that is used to decrypt/encrypt single tiddlers uses a symetric key [2] IMO you need to use public and private keys, to support this request [3], which is a copletely different system. At the moment every tiddler has a "uniqe" encryption, and who ever knows the password is able to open it. So security is bound to the password [2]. Public key encryption / decryption is bound to the owner of the public/private keys. ... So it is possible to encrypt a message for several recipients [3]. With this mechanism it is possible to have a "master" key (kind of a backdoor) that opens everything. The problem here is, that it needs quite a learning curve to handle such a system and imo the biggest one is the key handling and the UI. ...
