The result of the SHA384 digest algorithm * MUST NOT be truncated, and the entire 48-octet digest is published in * the ZONEMD record. * * SHA512 ([RFC6234]), with Hash Algorithm value 2, is also defined for * ZONEMD records and SHOULD be supported by implementations. When * SHA512 is used, the size of the Digest field is 64 octets. The * result of the SHA512 digest algorithm MUST NOT be truncated, and the * entire 64-octet digest is published in the ZONEMD record. * * Hash Algorithm values 240-254 are allocated for Private Use. * * The "ZONEMD Hash Algorithms" registry is further described in * Section 5. * * 2.2.4. The Digest Field * * The Digest field is a variable-length sequence of octets containing * the output of the hash algorithm. The length of the Digest field is * determined by deducting the fixed size of the Serial, Scheme, and * Hash Algorithm fields from the RDATA size in the ZONEMD RR header. * * The Digest field MUST NOT be shorter than 12 octets. Digests for the * SHA384 and SHA512 hash algorithms specified herein are never * truncated. Digests for future hash algorithms MAY be truncated but * MUST NOT be truncated to a length that results in less than 96 bits * (12 octets) of equivalent strength. * * Section 3 describes how to calculate the digest for a zone. * Section 4 describes how to use the digest to verify the contents of a * zone. * */ ISC_RUN_TEST_IMPL(zonemd) { text_ok_t text_ok[] = { TEXT_INVALID(""), /* No digest scheme or digest type*/ TEXT_INVALID("0"), /* No digest type */ TEXT_INVALID("0 0"), /* No digest */ TEXT_INVALID("0 0 0"), /* No digest */ TEXT_INVALID("99999999 0 0"), /* No digest */ TEXT_INVALID("2019020700 0 0"), /* Digest too short */ TEXT_INVALID("2019020700 1 1 DEADBEEF"), /* Digest too short */ TEXT_INVALID("2019020700 1 2 DEADBEEF"), /* Digest too short */ TEXT_INVALID("2019020700 1 3 DEADBEEFDEADBEEFDEADBE"), /* Digest type unknown */ TEXT_VALID("2019020700 1 3 DEADBEEFDEADBEEFDEADBEEF"), /* Digest type max */ TEXT_VALID("2019020700 1 255 DEADBEEFDEADBEEFDEADBEEF"), /* Digest type too big */ TEXT_INVALID("2019020700 0 256 DEADBEEFDEADBEEFDEADBEEF"), /* Scheme max */ TEXT_VALID("2019020700 255 3 DEADBEEFDEADBEEFDEADBEEF"), /* Scheme too big */ TEXT_INVALID("2019020700 256 3 DEADBEEFDEADBEEFDEADBEEF"), /* SHA384 */ TEXT_VALID("2019020700 1 1 " "7162D2BB75C047A53DE98767C9192BEB" "14DB01E7E2267135DAF0230A 19BA4A31" "6AF6BF64AA5C7BAE24B2992850300509"), /* SHA512 */ TEXT_VALID("2019020700 1 2 " "08CFA1115C7B948C4163A901270395EA" "226A930CD2CBCF2FA9A5E6EB 85F37C8A" "4E114D884E66F176EAB121CB02DB7D65" "2E0CC4827E7A3204 F166B47E5613FD27"), /* SHA384 too short and with private scheme */ TEXT_INVALID("2021042801 0 1 " "7162D2BB75C047A53DE98767C9192BEB" "6AF6BF64AA5C7BAE24B2992850300509"), /* SHA512 too short and with private scheme */ TEXT_INVALID("2021042802 5 2 " "A897B40072ECAE9E4CA3F1F227DE8F5E" "480CDEBB16DFC64C1C349A7B5F6C71AB" "E8A88B76EF0BA1604EC25752E946BF98"), TEXT_SENTINEL() };
