On: Bruce Schneier has changed his PGP key to 4096 bit...

[a--b]

I've been using 16,384 for my SSH key sizes for the past year and am considering using 32,768 a soon as my two year rotation period is up - would there be any problems with my key sizes?

[Qantourisc → a--b]

Long key generation, longer login time, possible lack of a proper entropy in the key, if the entropy source is not good.

[a--b → Qantourisc]

I'm okay with waiting, but the lack of entropy worries me a tad. Would that be super common with keys of that length? Thanks for the reply!
