com.bld.crypto.hmac.serializer.EncryptHmacSerializer<T>
Type Parameters:
T - the type of the value to sign
All Implemented Interfaces:
com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable, com.fasterxml.jackson.databind.jsonschema.SchemaAware, com.fasterxml.jackson.databind.ser.ContextualSerializer, Serializable
public class EncryptHmacSerializer<T> extends EncryptCertificateSerializer<T> implements com.fasterxml.jackson.databind.ser.ContextualSerializer
Jackson ContextualSerializer that signs a field value before writing it to the JSON output stream using HMAC.

The plain-text value is wrapped in a JSON envelope {"key":"&lt;annotationValue&gt;","value":"&lt;plainText&gt;"} and then signed. The envelope is verified during deserialisation to prevent cross-field substitution.
