Class Obfuscator

java.lang.Object

org.rhq.core.util.obfuscation.Obfuscator

public final class Obfuscator
extends Object

This class makes available methods for obfuscating a string in the very same way as the org.jboss.resource.security.SecureIdentityLoginModule in JBossAS 4.2.3.

This is to ensure backwards compatibility in case we switch containers that would start obfuscating the password in a different way and also to make those methods available to other code. The original methods in the SecureIdentityLoginModule are marked private.

Method Detail

encode

public static String encode(String secret)
                     throws NoSuchPaddingException,
                            NoSuchAlgorithmException,
                            InvalidKeyException,
                            BadPaddingException,
                            IllegalBlockSizeException

Encodes the secret string so that the value is not immediately readable by a "casual viewer".

Parameters:

secret - the string to encode

Returns:

encoded string

Throws:

NoSuchPaddingException

NoSuchAlgorithmException

InvalidKeyException

BadPaddingException

IllegalBlockSizeException

decode

public static String decode(String secret)
                     throws NoSuchPaddingException,
                            NoSuchAlgorithmException,
                            InvalidKeyException,
                            BadPaddingException,
                            IllegalBlockSizeException

Decodes the string obfuscated using the encode(String) method back to the original value.

This method differs from its original org.jboss.resource.security.SecureIdentityLoginModule#decode private method in that it returns a String whereas the original method returns a char[].

Parameters:

secret - the encoded (obfuscated) string

Returns:

the decoded string

Throws:

NoSuchPaddingException

NoSuchAlgorithmException

InvalidKeyException

BadPaddingException

IllegalBlockSizeException

generateString

public static String generateString(Random random,
                    String validCharacters,
                    int length)

Adapted from http://stackoverflow.com/questions/2863852/how-to-generate-a-random-string-in-java.

The default set of validCharacters: 1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

Parameters:

random -

validCharacters -

length -

Returns:
