As an alternative narrative — text:// uses saltpack + keys.pub to provide signing & encryption. Entirely bypassing the present PKI infrastructure altogether.  [1][2][3]

Claiming a host boils down to publishing one's handle over dns:

# dig +short _text._tcp.txt.textprotocol.org txt
"textprotocol@github" 

[1] https://saltpack.org
[2] https://keys.pub
