deadrop is an e2e encrypted secret sharing extension that leverages the Web Crypto API to share secrets directly between teammates and collaborators.
How it Works
Using public key infrastructure patterns, deadrop uses AES (with GCM) and Elliptic Curve (ECDH) cryptographic methods to generate keys and obfuscate payloads, then SHA-256 is used after handoff for verifying data integrity. All key and payload communications remain solely between the two peers ("dropper" and "grabber") over a direct WebRTC connection.
Usage
Dropping a Secret
Open the deadrop panel from the activity bar
Select Drop mode
Paste or type your secret
Hit Drop then you'll get a drop ID to share with the recipient
Grabbing a Secret
Open the deadrop panel from the activity bar
Select Grab mode
Enter the drop ID shared with you
Hit Grab then the secret will be decrypted and displayed directly in the panel
Note: Anonymous drops are subject to a pretty low daily limit. Sign up for a free account to get a higher limit.
