Constructor Detail

KmsDiscoveryKeyring

public KmsDiscoveryKeyring(KmsDiscoveryKeyring.Builder builder)

This keyring will decrypt the object without specifying the KMS key in its configuration. This is similar to the Encryption SDK's Discovery Keyring. NOTE: There is no Discovery Filter, as kms+context mode used in v2/v3 does not persist the KMS key ID to the object metadata, so it is not possible to safely filter on this attribute.

Parameters:
