2048 bits of RSA key is the same amount of security as 112 bits of symmentric key, though.

- xyzzyz 8y agoYes, that’s my point — you need to use 2048 bits for key to get 128 bits of security, so there is no way to fit the public key in the IPv6 address.
- grkvlt 8y agoCan't you do something with a key-stretching system [0] maybe, to turn 112 bits of IPV6 into 2048 bits of RSA input, though, since you definitely have the right amount of entropy? 0. https://en.wikipedia.org/wiki/Key_stretching https://en.wikipedia.org/wiki/Key_stretching
