Discord message encryption plugin that enables client side end-to-end encryption for your messages and files with automatic key exchange, works without BetterDiscord.
For Chrome (and similar)
download the extension from Chrome Webstore
Or download the dev extension and unpack it. Click on Menu > More tools > Extensions, enable Developer mode, click on Load unpacked and select the folder where you've unpacked the downloaded file.
If you have Discord installed, download the installer. Click the link and press Ctrl+S to save it as file. Launch Powershell as administrator, enter this command: Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass and enter the path to the file to execute it (i.e. cd C:\Users\You\Downloads\ShulkerRoadCrypt.ps1).
For mobile try Yandex Browser. The browser is Chromium based and supports extensions.
For Android install Discord APK and be sure to watch the tutorial.
Alternatively install it as userscript (with Tampermonkey) or include the js file somehow else.

Open the menu by right clicking on the lock icon.
Select the key you want to use in the drop down menu on top, next to the lock icon.
Toggle encryption by clicking the lock icon or use the prefix :ENC: or ENC at the start of your message to force encryption. To send non encrypted messages in a channel where encryption is turned on, use the prefix NOENC.
Download an encrypted image by middle clicking on the image.
Switch devices by exporting and importing your database. If you would like to use the plugin on multiple devices choose a main one, export the database (right click on lock icon > Export Database), right click on the lock icon (in on the secondary device) > New Database > Secondary). Repeat this after adding new keys in your primary device.
ECDH P-521 is used for the key exchange and AES256-CBC for the messages offering the equivalent security of 256-bits
Here you can find the original DiscordCrypt (discontinued).

The database password is optional but the database isn't! The database stores your keys and channel settings.
It is recommended to have only one database, multiple databases will mess things up. In order to manage this, you should keep backups by exporting your database regularly (right click on lock icon > Export Database).
If you would like to use the plugin on multiple devices choose a main one, export the database from that and click on secondary when importing. Repeat this after adding new keys.
If you import the database as secondary you can still export it and import it as primary database again. The difference is that a device with a secondary database will ignore key exchanges done on this device, which means you have to update your secondary devices with the new database.
You can paste these into the Ctrl+Shift+I console (Sadly with last chrome update it became maybe deprecated)
SdcClearChannels(filterFunc)
deleteBefore = (now = new Date()).setMonth(now.getMonth() - 6);
SdcClearChannels((channel) => (
//Number(channel.lastseen) ms precision unix timestamp
//String(channel.descriptor) descriptor from the channel manager
//Boolean(channel.encrypted) is the encryption toggled on
channel.lastseen < deleteBefore && //not seen in 6 months
/^DM with \d{17,20}$/.test(channel.descriptor) //name resolution failed
//'true' return value deletes the record
));SdcClearKeys(filterFunc)
deleteBefore = (now = new Date()).setMonth(now.getMonth() - 6);
SdcClearKeys((key) => (
//Number(key.lastseen) ms precision unix timestamp
//String(key.descriptor) descriptor from the key manager
//Boolean(key.hidden) is the key hidden
//String(key.type) one of ['GROUP', 'CONVERSATION'/*DM*/, 'PERSONAL']
//Number(key.registered) when the key was added to the database
key.lastseen < deleteBefore && //not seen in 6 months
/^(?:DM key with \d{17,20}|\d{17,20}'s personal key)$/.test(key.descriptor)
//name resolution failed if the id is used as name
//'true' return value deletes the record
));Keys are used to encrypt messages. Additional to that there is database key for encrypting the plugin's local database.
You can select which key to use for the channel at the top, besides the lock icon.
- Personal key: every user has a personal key (that is different for other users). It is used to encrypt messages in channels where are no other options available. It is shared with everyone you key-exchange with, so the security of it varies depending on the number of people you share it with.
- Group key: You can create a group key if you are in a group channel. Right click on the lock icon > Create Group Key. It is advised to change the name of the key right away to spot if someone accidentally generated a different key for your channel. You can do this in the Key Manager. After generating the group key, you can use it in other channels as well. If you set a group key in the Key Manager as hidden it will no longer show up in the drop down and it won't be automatically shared with your friends. If you really want to know if the other is using the same key as you, compare the first few characters (up to 16) of the encrypted message.
- DM key: These keys are generated by a Diffie-Hellman key exchange between two users, it provides a secure connection over an unsafe medium.
If the plugin comes across a message with a key that you don't have it will attempt to get that key by a key exchange with the sender of the message. You need to be able to DM the other user for the key exchange.
If a group key isn't set as hidden it will be shared automatically with a discord friend if they ask for it. (key exchange)
In order to share a key you need to establish a secure connection with an initial key exchange, it is usually automatic or can be started manually by right clicking on the lock icon > Start Key Exchange in the DM channel.
You can manually share keys by using the Share Keys menu option. During a key share, the sharing party will suggest you channels to use so it's advised to not set anything for the channel (or toggle encryption) before you have received the key for it.
Key rotation periodically generates a new key and switches to it in all channels that use the rotated key. Use SdcSetKeyRotation(7) in the console command to start a key rotation on the key of the current channel.
In the example above , the key changes every 7 days. By default this is aligned to arbitrary points so if you use the same command on your other primary devices (within a day, it will do the same). If the key is set to hidden, the new key will be hidden too.
Trusted Keys can be enabled in the Key Visualizer (in DM), this feature can be used to do automatic key exchange for hidden keys and/or rotated keys.
Keys shared with trusted keys can swap keys for channels automatically, which is useful for rotated keys.
You can click on an already enlarged image to further enlarge it, you can also drag the enlarged image if it doesn't fit the screen. Use the arrow keys to navigate like a gallery when zoomed in. You can use emojis (static and animated) in encrypted messages.
Encrypted messages above 1600 characters will be compressed, but this feature might have incompatibilities with future versions. This also means that the not encrypted messages can be 2000 character long if they are mostly made of normal characters. For large audio and video files, you can use Mega, it automatically embeds.
The encryption is completely secure unless someone at Discord replaces your messages right when you secure your DMs. To make sure you have the right keys, you can use the Key Visualizer and compare your result with the other party.
Getting notifications on custom phrases
This feature should be a good compensation for no searches and role mentions. (You use the console to tell you what can ping you or not).
Use the SdcSetPingOn(regexStr) console command to set the match string or regular expressions (regex) for extra pings.
For example SdcSetPingOn('An0') will only ping if the message contains that exact word, SdcSetPingOn(/\bAn[0o]\b/i) will match every form of it
Regex explanation:
/An0/only matches this exact expression/An[0o]/will matchAn0andAno/An[0o]/iwill be case insensitive, so it matchesanoandANOand everything in between`\bmeans word border, which means "start or end of word", so/\bano\b/won't find a match in the word 'another' (only works if you use letters, numbers or '_')/(?:An0|SimpleDiscordCrypt|SDC)/will match any of the three smaller regexes between the(?:)Please note that characters like.\\+?*()[]$^etc. have a specific function in regex and should be escaped with\.
Sample regex for role mentions:
/<@&(?:473998238156849152|474006463749160992)>/
You can get the role ids with \@Role in the chat
To uninstall, just delete it from %localappdata% and make new shortcuts.
