All Implemented Interfaces

Serializable, javax.ejb.EnterpriseBean, javax.ejb.SessionBean

public class DecryptorImpl
extends SessionImpl

The DecryptorImpl is the implementation used by the Decryptor service.
It uses RSA standard private key encryption for the implementation. The server should be in a consistent state before decryption services can be provided. If decryption services are requested of the Decryptor before the server is appropriately initialized, it throws an InconsistentStateException.

decrypt

public String decrypt(String dataToDecrypt)
               throws InconsistentStateException

Takes a byte string of data to decrypt and returns a string of plain text.
The decryption process involves getting an instance of the KeyFactory and retrieving the private key from it. The encrypted data, which is really a base-64 encoded string, is then decoded to convert it to the byte sequence that the Encryptor returned as a result of the encryption process. This byte sequence is then passed on the decryption routine to get back the original text. A SystemException is thrown if the string being decrypted was encrypted using a public key that is not part of the key pair that the private key is a part of.

Parameters

dataToDecrypt - The encrypted string that needs to be decrypted.

Returns

s string of decrypted data.

Throws

InconsistentStateException - if the server is not initialized with decryption password.
