Profile Operations

A Profile is just a specially registered Public Key. Register this endpoint by posting to the service key with the desired profile-public-key. If you register with some Profile data, that will be saved. Register your public key and perhaps provide some information. Other users can then publish to your inbox.

curl \
    -X POST \
    --header 'authorization: OpenTHC $PROFILE_AUTH_BOX' \
    --header 'content-type: application/json' \
    --data '$PROFILE_JSON' \
    https://openthc.pub//$PROFILE_PK

A profile is simply a public-key that is registered in the system. Send a POST/PUT to your public-key with your profile information encrypted to the service public-key

curl https://openthc.pub//$PK \
  -X POST \
  --header 'content-type: application/octet-stream' \
  --data '$JSON_BOX'

Update A Profile

Create the input.txt file as encrypted data using your profile-secret-key and the service-public-key. The contents of input.txt should be one large binary string.

sodium-encrypt $SECRET $PUBLIC $SOURCE > input.txt
curl -X POST https://openthc.pub//$PROFILE_PK --data @input.txt

Send a Message to a Profile

Just POST a message to a public key. The message may or may not be encrypted. The body is saved AS-IS and the indicated content-type is (mostly) trusted. These end-points are write-once. Only the public-key owner may fetch these documents.

Encrypt the data then POST from your PUBLIC_KEY to their PUBLIC_KEY/ The input data can be either a) text/plain or b) application/json or c) application/x-www-form-urlencoded.

The profile-public-key, if registered on this endpoint, will have the message stored in their incoming queue.
