accessKey property
AccessKey (pk-) is the publishable identifier and lookup index; AccessSecret (sk-) is the confidential secret. AccessSecret IS NOT PERSISTED for a key minted at or after the digest change: it carries the secret out to its holder once, in the mint response, and the row keeps only AccessSecretDigest. It stays on the struct because that one-time reveal is the whole point of minting, and it stays in the schema because rows written before the change still hold a plaintext secret that the resolver drains on first use.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? accessKey;
