DiscordCrypt - Encrypt Your Discord Messages and Files
DiscordCrypt, built by SimpleCrypto, allows you to encrypt your messages and files in Discord. It works from both the browser and on your computer, without BetterDiscord, and can be used in any channel, including Discord voice channels, guilds, and more. With the built-in server-side encryption and random keys, the data is only visible to the recipient(s). You can encrypt multiple messages at once with the same key.
In DiscordCrypt, you can use the built-in server-side encryption to encrypt all your files while setting a different key for each file. You can also set the time the files are encrypted and how they are unlocked.
Encryption is handled automatically by SimpleDiscordCrypt, so you don't need to do anything.
