Project state

Project is in working condition.

There are still a few things to add, and docs need updating.

The v1 protocol is likely finalized: the 2 byte header defines scrypt N and r parameters, salt and HMAC lengths, ascii-only encoding, and lower-case-only passwords.

Documentation is needed for that.

Compiling yourself

This repository tries to modify third party code as little as possible, and will provide ways for you to generate it yourself.

# NOTE: the --recursive is important
git clone --recursive https://github.com/aurorabbit/emojicrypt.com.git
cd emojicrypt

# checkout specific git commits
git --git-dir .git/modules/scrypt-js checkout 6254d45eb7edd38413c2672e14b42a1a1ad22781 # v2.0.3
git --git-dir .git/modules/base-emoji checkout 76ed24270be28a1ab9473a22cd43d2253cd4a06e # lastest

# generate js/emoji256.{js,json}
node gen-emoji256.js

# patch base-emoji to use the different emoji format
patch -o js/pfrazee-base-emoji.js base-emoji/index.js base-emoji.patch

Planned

This is written on a piece of paper, I may port it soon or just complete it.
