Encrypted ClientHello (ECH) key pairs need to be configured into TLS
servers, which can be built using different TLS libraries. This
document specifies a standard file format for this purpose, similar
to how RFC 7468 defines other Privacy-Enhanced Mail (PEM) file
formats.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
