So I've been doing some reading and looking at my overall setup and I'd like to shift to a more secure email system than the one I'm currently using. In addition, I want to generate a new keypair of 4096 length instead of 2048.
The trick comes in doing this without alarming the jumpier members of our community who could see this as me being subverted by LE. Any advise on how to do this in the least painful way possible is deeply appreciated. TIA
It's impossible to increase the length of an existing key; sending a transitional statement may be your best bet, since you could sign the statement containing the new key with your old key.
