getUriForAuthorization

getUriForAuthorization(registryUri, delegateAddress, creatorAddress): Promise<RegistryAuthorizationUri>

Generates a URI for authorization based on the provided registry URI, delegate address, and creator address.

This function computes a unique authorization URI by creating a digest from the registry identifier, the delegate’s address, and the creator’s address.

Parameters

• registryUri: `registry:cord:${string}`

The URI of the registry for which authorization is requested.

• delegateAddress: string

The address of the delegate for whom the authorization URI is generated.

• creatorAddress: string

The address of the creator of the registry, used for authentication.

Returns

Promise<RegistryAuthorizationUri>

A promise that resolves to the generated authorization URI for the specified registry.

Usage Example:

const registryUri = 'some-registry-uri'; // Example registry URI
const delegateAddress = 'some-delegate-address'; // Delegate address
const creatorAddress = 'some-creator-address'; // Creator address

try {
  const authorizationUri = await getUriForAuthorization(registryUri, delegateAddress, creatorAddress);
  console.log(`Authorization URI: ${authorizationUri}`); // Logs the generated authorization URI
} catch (error) {
  console.error(error);
}

This function first encodes the registry identifier and addresses into byte arrays, then calculates the Blake2 hash digest of the combined data to create a unique authorization URI.
