question: strengthen a key which might be too short by extending with a salt text concode_field_sep int MAX_KEY_LENGTH concode_elem_sep char[] hexChars concode_field_sep String encrypt concode_elem_sep String decrypt
target: String function ( String arg0 , String arg1 ) { if ( arg0 . length ( ) > BlowFish . MAX_KEY_LENGTH ) return arg0 ; arg0 = arg0 + arg1 ; return arg0 . substring ( 0 , BlowFish . MAX_KEY_LENGTH ) ; }
