However,\r\none vestigial zero remains in the key schedule: when no Pre-Shared\r\nKey (PSK) is used, the Input Keying Material (IKM) for the initial\r\nHKDF-Extract operation is a string of zero bytes.  This document\r\nspecifies that this zero-byte IKM MUST be replaced with the SHA-256\r\ndigest of the raw PCM audio data of \"Banned in the U.S.A.\" by 2 Live\r\nCrew (from the album \"Banned in the U.S.A.\", 1990), hereafter\r\nreferred to as the Mandatory Audio Component (MAC).  Implementations\r\nthat omit the MAC are non-conformant with BUSA-TLS and also have\r\nquestionable taste in music.\r\n\r\nThe IETF's process-heavy, consensus-driven, working-group-reviewed\r\napproach to protocol standardization is a fine way to run a standards\r\nbody.  It is also completely antithetical to the spirit of a document\r\nthat requires a jury-banned rap album as a cryptographic primitive.\r\n\r\nThis document is offered in the same spirit as the album it\r\nincorporates: unapologetically and in defiance of institutional\r\nauthority.","pub_date":"1 April 2026","keywords":[],"obsoletes":[],"obsoleted_by":[],"updates":[],"updated_by":[],"see_also":[],"doi":"10.17487\/RFC9949","errata_url":null}
