> Also be careful around compilers and interpreters. No mainstream language specifies how to make constant time code, so your tools could insert secret dependent branches where the source code had none. High level languages in particular tend to have variable time arithmetic. In practice, low level languages like C are fairly reasonable, but I've seen exceptions. This is by definition not simple if the very tools you're using can cause what you think is correct to be wrong and dangerous!
