Hi Rich,

We speak of reaching data limits, and the process of changing the key has many 
names, e.g. key rotation, key renewal, key refreshing, key updating.

Any of those ring a bell?

Cheers

Kenny

Subject: [TLS] What's it called

I’m blanking on a term and web searches turn up too much useless info.

What is it called when we have to start using a new symmetric key because we’ve 
encrypted too much data with the old one?  Key exhaustion fits, but probably 
isn’t it.
