Good writeup. Since I can already see not everyone here actually read the article, here are some highlights. > Law enforcement has always been able to request information from us through the Telecommunications Act with a lawful warrant. Because we have the ability to decrypt all data, there is no need to make changes that circumvent encryption. ... While FastMail is not directly affected, we don’t support this legisl…

Thanks - that's pretty much exactly it. If someone needs end-to-end encryption, it's only safe from intermediate third parties if they aren't trusting software which is updated by those third parties.

So we use effective methods to protect the privacy of our users while performing our civic duty of assisting law enforcement when bad actors use or abuse our platform, and we never pretend to use the bulk of our customers as human shields to protect bad actors trying to hide among them.

Earlier quoted context omitted.

I didn't think Canada was doing much better than us (Australia) with these kind of crazy, over-reaching laws. You'd probably have to find somewhere in Europe.

Switzerland might be better as not part of five eyes.

Switzerland probably is too expensive.

So the article's tl;dr is basically: "We're advocating for privacy, but we aren't going to try to offer you any. We never did, and we certainly won't now that this law passed. You're on your own."

Is this supposed to be a PR-positive announcement from FastMail, because I can't quite tell?!

Im hoping to resolve this using a "searchable encryption" scheme leveraging homomorphic encryption and elliptic curve based el-gamal. This would allow law enforcement to search for key words on encrypted data sets. This prevents leakage for both parties.

THe use case for emails is a tad clunky as the bag of words would require precomputing, however, it is privacy preserving for both parties.

If you feel this is something interesting that you would like to contribute to please msg me. I have working code in javascript (so it may soon be a plugin) and the architecture is decentralized but requires a a single message interaction between the actor querying and the data source.

Their "Actions we are taking" section is almost entirely composed of a political lobbying strategy. Given the outcome of the vote, 44 votes for and only 12 against, their plan doesn't exude much confidence. I would have expected plans to move data and key technologists out of Australia at the very least.

The company I work for uses Fastmail but our CEO has already decided to switch mail providers sometime in 2019. I don't know what other service they'll choose.

I got the exact same feeling from reading this.

It almost feels like it’s written for the Aussie Police and not really for the users.

1. Once a user identifies messages containing the search term, what are they supposed to do then? The message should still be un-decryptable to them.

2. Can't a user search all common words against a message and then rearrange those found to roughly match the message length. There are only so many ways the words "noon begins the tomorrow revolution at" can be arranged and make sense.

We never offered, and never claimed to offer, a safe haven for people who have broken the law in both Australia and their own country to hide from the police. We don't place ourselves above law enforcement.

We don't have data trading agreements with anybody, and we don't sell or provide backdoor channels - we only provide data in response to lawful warrants.

That's the right amount of privacy and the right tradeoff with usability for just about everyone. Certainly storing your emails super encrypted in a concrete bunker on an island somewhere is theoretically safer along one axis - I wrote a whole series about Confidentiality, Availability and Integrity just over 4 years ago on this very topic: https://fastmail.blog/2014/12/02/security-confidentiality-in...

And the specific one on confidentiality here: https://fastmail.blog/2014/12/15/security-confidentiality/ (excuse the line wrapping, we moved to a new blog platform a while back and some of the older posts didn't import perfectly, but I don't want to look suspicious by editing it today!)

Not at all.

If you want to use PGP for encrypted email, and they supported it e.g. in their webmail - that would open them up to being a valid 'target' for the new bill, to provide access to your encrypted messages.

If they're just a conduit for your PGP (or even S/MIME) encrypted messages, the government can compel them all they like - there's literally nothing they can do to decrypt those messages.

Note: I am not a customer, or involved in FastMail at all (I am Australian though). This is just one of the facets of encrypted email IMO - if it's decrypt able somewhere between your laptop/phone/etc and the other persons laptop/phone/etc, it's not end-to-end encrypted, is it?
