Signing a message

To sign an arbitrary message,

1. Go to https://creatorsgarten.org/dashboard/sign
2. Type in the message to sign, for example, "hello world".
3. Click Sign message and you will get a signature.

Example signature looks like this:

grtn_v1_b94d27b9934d3e08a52e52d7_644c35a6802c02345887f156_6616f6372507e7e12f17c2b7_1af9dcc56879174816dbb6e9

Asking people to sign a message

You can construct a URL with ?signMessage query param, e.g.

https://creatorsgarten.org/dashboard/sign?signMessage=hello+world

When a person visit this link, this will make them sign the message "hello world". If they want to use the signature, they can copy the signature.

Verifying a signature

Make a GET request to https://creatorsgarten.org/dashboard/sign/verify, passing ?signature query param, e.g.

https://creatorsgarten.org/dashboard/sign/verify?signature=grtn_v1_b94d27b9934d3e08a52e52d7_644c35a6802c02345887f156_6616f6372507e7e12f17c2b7_1af9dcc56879174816dbb6e9

If a signature is valid, you get an object back, like this:

{
  "verified": true,
  "messageHash": "b94d27b9934d3e08a52e52d7",
  "userId": "644c35a6802c02345887f156",
  "timestamp": "2024-04-10T20:27:35.000Z",
  "nonce": "6616f6372507e7e12f17c2b7"
}

Field	Description

messageHash	SHA-256 hash of the message, truncated to 24 characters
userId	User ID of the person who signed the message (you can find your user ID in /dashboard)
