Class PublicKeyEncryptionServiceImpl

  • All Implemented Interfaces:
    java.util.Iterator<CipherVersion>, CipherVersionGenerator<CipherVersion>, EncryptionService, org.refcodes.generator.Generator<CipherVersion>

    public class PublicKeyEncryptionServiceImpl
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.
