java.lang.Object | +--bees.core.security.Signature
Signature is a thin veneer over the standard java.security.Signature class that uses bees.core.security classes.
Note: In order to prevent downloaded code from producing signatures for arbitrary data, the flow identifier is always added to the signature.
