All Implemented Interfaces:

Runnable, Future<Void>, RunnableFuture<Void>, Plugin, TextEncrypter

public class RsaCipher
extends AbstractPluginAdapter
implements TextEncrypter

Encrypter backed by RSA, making it possible to decrypt the result string. This implementation needs public key resource to encrypt, either the PUBLIC_KEY or one that is custom defined looked for on the classpath. The public/private keypair can be easily generated with RsaKeyGenerator.generateKeyPair(boolean, int, java.io.File, java.io.File).

Field Detail

PUBLIC_KEY

public static final String PUBLIC_KEY

Public key resource name and path this cipher needs for encryption. This file should be on root classpath of the packaged jar.

Constant Field Values

Constructor Detail

RsaCipher

public RsaCipher()
          throws IOException

Constructs instance backed by PUBLIC_KEY. Exception is thrown if that file is not found.

Throws:

IOException - if public key file is not on classpath

RsaCipher

public RsaCipher(String publicKeyResourcePath)
          throws IOException

Constructs an instance backed by user defined resource representing a valid public key. Unlike the default constructor which looks for specific resource at the specific location, this resource can be anywhere in the classpath hierarchy.

Parameters:

publicKeyResourcePath -

Throws:

IOException

Method Detail

encrypt

public String encrypt(String text)

Description copied from interface: TextEncrypter

Encrypts single string of text with the implementation specific algorithm. This could be a non-decryptable digest, decryptable string given a right cipher, or even unmodified string depending on the algorithm used.

Specified by:

encrypt in interface TextEncrypter

Parameters:

text - value to be encrypted

Returns:

encrypted value

decrypt

public String decrypt(String cipherText,
             PrivateKey privateKey)

decrypt

public String decrypt(String cipherText,
             String privateKeyResourcePath)
               throws IOException

Throws:

IOException
