End-to-End Encryption: AES-GCM encryption is used to encrypt your data before sending it to the server

API

Store a secret

PLEASE NEVER EVER UPLOAD UNENCRYPTED SECRETS.

This endpoint is only meant to store already encrypted secrets. The encrypted secrets are stored in plain text.

$ curl -XPOST -s https://envshare.dev/api/v1/secret -d "already-encrypted-secret"

You can add optional headers to configure the ttl and number of reads.

$ curl -XPOST -s https://envshare.dev/api/v1/secret -d "already-encrypted-secret" -H "envshare-ttl: 3600" -H "envshare-reads: 10"

Omitting the envshare-ttl header will set a default of 30 days. Disable the ttl by setting it to 0. (envshare-ttl: 0)
Omitting the envshare-reads header will simply disable it and allow reading for an unlimited number of times.

This endpoint returns a JSON response with the secret id:

{
  "data": {
    "id": "HdPbXgpvUvNk43oxSdK97u",
    "ttl": 86400,
    "reads": 2,
    "expiresAt": "2023-01-19T20:47:28.383Z",
    "url": "http://envshare.dev/api/v1/secret/HdPbXgpvUvNk43oxSdK97u"
  }
}

Retrieve a secret

You need an id to retrieve a secret. The id is returned when you store a secret.

$ curl -s https://envshare.dev/api/v1/secret/HdPbXgpvUvNk43oxSdK97u

{
  "data": {
    "secret": "Hello",
    "remainingReads": 1
  }
}
