All Implemented Interfaces:

public class PublicKeyEncryptionService
extends AbstractEncryptionService

This Encryption-Service uses a public key for an asymmetric encryption algorithm in order to encrypt any ciphers being generated before them ciphers are passed to the Encryption-Server which persists them cipher versions with the cipher UID and the encrypted cipher. A decryption server may retrieve the cipher versions with the cipher UID and the encrypted cipher and pass it to a Decryption-Service which might decrypt the ciphers with an according private key.

                                  GeneralSecurityException

Constructs the service with the required services and configuration.

Parameters:

aNamespace - The name space to which this service belongs

aPublicKeyPath - The path on the file system to the public key to be used for encrypting any ciphers passed to the Encryption-Server for persisting.

aEncryptionServer - The server to which the service is being "connected"

Throws:

edu.vt.middleware.crypt.CryptException - in case a crypt exception occurred when instantiating the public key

IOException - in case reading the file public key caused IO problems

GeneralSecurityException - in case a security poroblem was encountered.
