ProtonMail adds support for Web Key Directory (WKD), DANE, and MTA-STS:
– WKD is also available for external keys now
– DANE is also available for custom domains
– Besides, they added HTTP headers (Expect-CT, Public-Key-Pins-Report-Only), DNS CAA, and monitoring (e.g., TLSRPT)
– There will be an independent security audit of all Proton apps
@infosechandbook woho! Been looking forward to this for... maybe three years?
Now how do I implement that key server on my domain then?
