The sriString Datatype​

It MUST conform to the definition in Verifiable Credentials Data Model v2.0 Section B.3.1. For permitted hashes, they MUST conform to hash algorithms.

Example 1:

sha256-GtNUUolQVlwIkQU9JknWkwkhfdiVmHr/BOnLFFHC5jI=

Example 2:

sha256-I4OoejARWbxpTQ1HEccoxIaOIMUjEIgxEfJXJDAjwoI=
sha384-dN4FeVmV5DQb/C8iAY+sBUjLjFfB+knXZJ3RT2GyJg8Tco4SPQYwxNpe2M50b9ON

The image Datatype​

The value of the image data type is a JSON-LD Node Object and contains the following properties:

  • id: REQUIRED. The URL of the image.
  • digestSRI: RECOMMENDED. A hash value to ensure the integrity of the image. It MUST be of the sriString datatype.

Example:

{
  "id": "https://example.com/image.png",
  "digestSRI": "sha256-OYP9B9EPFBi1vs0dUqOhSbHmtP+ZSTsUv2/OjSzWK0w="
}

Verifying image Datatype​

A verifier can verify properties of the image datatype by following these steps (OPTIONAL):

  1. Get the image by sending a GET request to the URL of the id property.

  2. Verify the image obtained in 1. against the digestSRI property by the method as specified in SRI section 3.3.5.
