Say I have a page on my website which lists public keys to be used in case people would either allow me access to a server, or send me encrypted information.
Is there any benefit to me providing different types of keys for users to use, or multiple keys of the same type but different sizes?
For example, a page on my website that looks like this (with links to the full keys, not just the fingerprints):
RSA v2 (2048 bits):
RSA v2 (4096 bits):
