    abstract =  {This document specifies an extension to the SSLKEYLOGFILE format to support the logging of information about Encrypted Client Hello (ECH) related secrets. Two new labels are introduced, namely ECH\_SECRET and ECH\_CONFIG, which log the Hybrid Public Key Encryption (HPKE)- derived shared secret and the ECHConfig used for the ECH, respectively. This extension aims to facilitate debugging of TLS connections employing ECH.},
