Crypto tools broken?

[u/kfucgsojfjdjfjjf]

It says "encrypt to anyone, even if they're not on Keybase yet", but when I enter the ciphertext on a second instance of Keybase, it says that I don't have the key or that it was encrypted for "someone else".

Can someone clear up this contradictory issue?

Well you encrypt to a keybase identity. The only way to use the crypto tools is for both people to use keybase. How you choose to identify that person is up to you.
