Thanks! I didn't, but maybe I should have. I thought the API of scrypt.js would work well and don't think I came across anything better. I also figure scrypt is plainly better than PBKDF2; being designed from ground up for key lengthening and offering memory hardness. I figure bitcoin ASICs might be repurpose-able to attack PBKDF2; though I'm not sure if that's a threat, and I imagine it mostly somewhat applies to scrypt anyway because of litecoin and friends. If I were more worried I would have researched the default parameters more, I think this is 128- vs 256-bit territory.

On the topic of toy web crypto projects, here's mine: https://emojicrypt.com/

It offers scrypt + aes-gcm, encoded into 256 emoji; all the crypto is in https://github.com/aurorabbit/libemojicrypt/blob/master/prot... (I could have went without a subrepo, but in theory it makes non-web integration or alternate interfaces simple.)

It's based off of ricmoo's scrypt.js, pfrazee's base-emoji, and WebCrypto.

Output contains a header (with N/r parameters), salt, IV, and HMAC. Room for a dozen more protocol versions as well.

It's abandoned, looking for a loving home! Work for some new (and some unimplemented) features is laid out here: https://github.com/aurorabbit/emojicrypt.com/issues

I began work on a project for exactly this 2 months ago.

https://aurorabbit.github.io/emojicrypt.com/

It encrypts messages with a passphrase using scrypt, AES-GCM, and sha256 for an HMAC.

Each v1 protocol message includes a salt/iv, scrypt N&r, HMAC, and whether or not to lower-case the password. All messages encrypted with the proof-of-concept will be decrypt-able by all future clients, as there's room for 13 more protocol versions.

The code is in complete disarray, and I wouldn't want anyone to sift through it in it's current state[1], but the proof-of-concept is finished, and life came up, so it's been sitting since.

I have a list of features[2] I want to add in the issues tracker :)

[1] if you do want to sift through it don't miss https://github.com/aurorabbit/libemojicrypt. I separated the repos without following through on that reorganization.

I've used WebDAV successfully for a client's network storage system.

I use Apache2 + SQLite for the authentication, here is an example configuration: https://gist.github.com/aurorabbit/36c509ddeeba2b97c3019534f...

I use buildroot for creating a minimal linux install.

emojicrypt.com – encrypt messages into emoji using scrypt and aes-gcm!

https://aurorabbit.github.io/emojicrypt.com/

Unfortunately hackernews doesn't seem to support emoji properly, so I've put my message here:

https://gist.github.com/aurorabbit/fdab58373cb7a57bfc621c2f4...

The passphrase is the Ask HN submission id :)

Woah, that would mean e-Residency in Estonia would be enough for GDPR protections, right?

Note that becoming one involves going to your embassy in person.
