question: public static char [ ] deObfuscate ( String ePassword ) { if ( ePassword == null ) return null ; byte [ ] bytes = null ; try { bytes = SimpleBase64Encoder . decode ( ePassword . substring ( xorTag . length ( ) ) ) ; } catch ( Exception e ) { return null ; } for ( int i = 0 ; i < bytes . length ; i ++ ) { bytes [ i ] = ( byte ) ( ( bytes [ i ] ^ key [ i % key . length ] ) & 0x00ff ) ; } return toChar ( bytes ) ; }
target:  The inverse operation of obfuscate: returns a cleartext password that was previously obfuscated using the XOR scrambler.
