The point I was trying to make is that 1 month key rollovers
far exceed best pactice for 1024 bit key sizes. Where best
practice is looking at military requirements. If you look
in your brower you will probably see 1024 bit certificates
with lifetimes of 20 years which is commercial requirements.
Rolling a 1024 bit key every 5-10 years should be fine but
you are likely to forget how to do it properyly.
There isn't one answer that will fits the actual usage
I don't roll by keys monthly. I'll do it annually, and
even then it will be overkill for what it is protecting,
but I'm also unlikely to forget how to it.
