Method: digest

Returns the checksum ("digest") of an unwrapped Data Encryption Key (DEK).

SHA-256("KACLMigration" + resource_identifier + unwrapped_dek)

HTTP request

POST https://<kacls_url>/digest

Path parameters

None.

Request body

The request body contains data with the following structure:

JSON representation
{ "authorization": string, "reason": string, "wrapped_key": string }

Fields

Fields
`authorization`	`string` A JWT asserting that the user is allowed to unwrap a key for `resource_name`. See authorization tokens.
`reason`	`string (UTF-8)` A passthrough JSON string providing additional context about the operation. The JSON provided should be sanitized before being displayed. Max size: 1 KB.
`wrapped_key`	`string` The base64 binary object returned by `wrap`.

authorization

string

A JWT asserting that the user is allowed to unwrap a key for resource_name. See authorization tokens.

reason

string (UTF-8)

A passthrough JSON string providing additional context about the operation. The JSON provided should be sanitized before being displayed. Max size: 1 KB.

wrapped_key

string

The base64 binary object returned by wrap.

Response body

If successful, this method returns a checksum of the unwrapped DEK with the resource_name and "KaclMigration" prepended to allow validation of correctness.

If the operation fails, a structured error reply should be returned.

JSON representation
{ "checksum": string }

Fields

Fields
`checksum`	`string` SHA-256 of the unwrapped DEK with the Resource ID and "KaclMigration" prepended. This string should be a 43-character base64 string.
