title: security find-generic-password command for safari returning some garbage value
body: <p>I want to find the Safari Extensions List password from the keychain. I am doing it through NSTask now, As soon as we launch the task, it is printing some password. But When I store the password in some NSString using,
  NSString * password = [[NSString alloc] initWithData:dataRead encoding:NSASCIIStringEncoding];
  it is returning some other value. Is there any other way to read the output of NSTask/NSPipe?</p>
