Class OldJavaCrypt

java.lang.Object
  org.apache.turbine.services.crypto.provider.OldJavaCrypt

All Implemented Interfaces:

CryptoAlgorithm

public class OldJavaCrypt

extends java.lang.Object

implements CryptoAlgorithm

This is the Message Digest Implementation of Turbine 2.1. It does not pad the Base64 encryption of the Message Digests correctly but truncates after 20 chars. This leads to interoperability problems if you want to use e.g. database columns between two languages. If you upgrade an application from Turbine 2.1 and have already used the Security Service with encrypted passwords and no way to rebuild your databases, use this provider. It is bug-compatible. DO NOT USE THIS PROVIDER FOR ANY NEW APPLICATION! Nevertheless it can be used as the default crypto algorithm .

Method Detail

setCipher

public void setCipher(java.lang.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.

setSeed

public void setSeed(java.lang.String seed)

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

Specified by:

setSeed in interface CryptoAlgorithm

Parameters:

seed - Seed (ignored)

encrypt

public java.lang.String encrypt(java.lang.String value)
                         throws java.lang.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:

java.lang.Exception - An Exception of the underlying implementation.
