Class JavaCrypt

java.lang.Object

org.apache.fulcrum.crypto.provider.JavaCrypt

All Implemented Interfaces:

CryptoAlgorithm

public class JavaCrypt
extends Object
implements CryptoAlgorithm

Implements the normal java.security.MessageDigest stream cipers. Base64 strings returned by this provider are correctly padded to multiples of four bytes. If you run into interoperability problems with other languages, especially perl and the Digest::MD5 module, note that the md5_base64 function from this package incorrectly drops the pad bytes. Use the MIME::Base64 package instead. If you upgrade from Turbine 2.1 and suddently your old stored passwords no longer work, please take a look at the OldJavaCrypt provider for bug-to-bug compatibility. This provider can be used as the default crypto algorithm provider.

Method Detail

setCipher

public void setCipher(String cipher)

Setting the actual cipher requested. If not called, then the default cipher (SHA) is used. This will never throw an error even if there is no provider for this cipher. The error will be thrown by encrypt() (Fixme?)

Specified by:

setCipher in interface CryptoAlgorithm

Parameters:

cipher - The cipher to use.

See Also:

CryptoAlgorithm.setCipher(java.lang.String)

setSeed

public void setSeed(String seed)

This class never uses a seed, so this is just a dummy.

Specified by:

setSeed in interface CryptoAlgorithm

Parameters:

seed - Seed (ignored)

See Also:

CryptoAlgorithm.setSeed(java.lang.String)

encrypt

public String encrypt(String value)
               throws Exception

Encrypt the supplied string with the requested cipher

Specified by:

encrypt in interface CryptoAlgorithm

Parameters:

value - The value to be encrypted

Returns:

The encrypted value

Throws:

Exception - An Exception of the underlying implementation.
