Ukubuka konke okubonakalayo okuningiliziwe komsebenzi we-HAVAL-160/5 cryptographic hash, okubonisa ukucubungula komlayezo kusengaphambili, ama-transformation passes amahlanu, imisebenzi eyindilinga, kanye ne-digest yokugcina ye-160-bit.

Izinguqulo ezitholakalayo zalesi sithombe
Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.
Usayizi ojwayelekile (1,536 x 1,024)
Usayizi omkhulu (3,072 x 2,048)

Incazelo yesithombe
Isithombe siyi-infographic ebanzi, enesinqumo esiphezulu yedijithali ekhombisa ukuhamba komsebenzi kwangaphakathi kwe-algorithm ye-HAVAL-160/5 cryptographic hash. Esikhungweni esiphezulu, isihloko esiqinile sensimbi sifunda "HAVAL-160/5 HASH ALGORITHM" esinombhalo ongezansi othi "160-BIT HASH • 5 PASSES • 80 ROUNDS." Uhlelo lombala oluphelele lushintsha lusuka koluhlaza okwesibhakabhaka okupholile ngakwesobunxele luye kumibala efudumele ye-amber ne-orange ngakwesokudla, okufanekisela ukugeleza kwedatha kusuka kokufaka kuya kokukhipha kokugcina, ngesizinda esicashile sezinombolo ezimbili kanye nemikhondo efana neyesekethe.
Ngakwesobunxele impela, ingxenye ebhalwe ukuthi "INPUT MESSAGE" ikhombisa umugqa wamaseli emiyalezo angunxande. Ngezansi kwayo, ibhokisi elinesihloko esithi "PADDING & LENGTH APPENDING" libonisa isinyathelo sokucubungula kusengaphambili. Umcibisholo uholela phansi kuphaneli enkulu enohlaka oluhlaza ebhalwe ukuthi "512-BIT DATA BLOCK," ehlukaniswe ngokuthi "BLOCK 1," "BLOCK 2," kanye nokuthi "BLOCK N," okubonisa indlela umlayezo ohlanganisiwe ohlukaniswe ngayo ukuze ucutshungulwe.
Ngaphezu kwalokho, ibhokisi elibhalwe ukuthi "INITIAL HASH VALUE" liqukethe amarejista amancane amahlanu abhalwe ukuthi A, B, C, D, kanye no-E, amele amagama asebenzayo. Lawa angena emgudwini ophakathi, lapho amathebhu anemibala emihlanu abhalwe ukuthi "PASS 1," "PASS 2," "PASS 3," "PASS 4," kanye no-"PASS 5" ahlelwe ngokuvundlile, kugcizelelwa isakhiwo se-HAVAL sokudlulisa okuningi.
Phakathi nomdwebo, iphaneli evelele enesihloko esithi "BITWISE OPERATIONS" ibala imisebenzi eyisisekelo enengqondo esetshenziswa yi-algorithm: AND, OR, XOR, SHIFT, kanye no-NOT, ngayinye imelelwe ngezithonjana ezinesitayela. Ngaphansi kwayo, elinye iphaneli elibhalwe ukuthi "SUBSTITUTION TABLES" libonisa amabhokisi abizwa ngokuthi S1, S2, S3, S3 (akopishwe ngendlela yesitayela), kanye no-S4, eqokomisa ukuguqulwa okungekhona okuqondile okusetshenziswa ngesikhathi somjikelezo ngamunye.
Ngaphansi kwalokhu, indawo ethi "ROUND FUNCTIONS" ikhombisa ukugeleza kweziguquguquko ngemicibisholo nama-operation node. Amabhulokhi abhalwe u-A no-C adla into ejikelezayo ebhalwe ukuthi "ROT," bese efakwa ku-node yokususa noma yokuxuba bese eqhubekela ku-E, kanye nebhulokhi eqhubekayo eyengeziwe ebhalwe ukuthi u-K efakwe endleleni. Emaphakathi aphansi, ibheji elimnyama elifundeka ngokuthi "80 ROUNDS" lifingqa inani eliphelele lokuphindaphinda okwenziwe kuwo wonke ama-pass amahlanu.
Ngakwesokudla, isigaba esinesihloko esithi "FINAL OUTPUT" siqukethe ibhokisi elibhalwe ukuthi "HAVAL-160/5" elikhomba ku-"160-BIT HASH VALUE." Isampula ye-hexadecimal digest eqala ngo-"50 AF D1 7C 12 93 E5…" iboniswa ukuze ibonise ifomethi yemiphumela. Ngezansi, imigoqo emihlanu evundlile ebhalwe ukuthi H0, H1, H2, H3, kanye ne-H4 ibekwe ndawonye, ngayinye inombala ohlukile we-gradient ofudumele, emele amagama amahlanu angu-32-bit ahlanganisa ndawonye akha i-hash yokugcina engu-160-bit.
Sekukonke, i-infographic ihlanganisa ukuthayipha okuhlanzekile, izigaba ezinemibala, imicibisholo, namaphaneli e-modular ukuqondisa umbukeli isinyathelo ngesinyathelo ngenqubo ye-HAVAL-160/5 hashing, kusukela kumlayezo wokufaka ongavuthiwe kuya ekucutshungulweni kwangaphambilini, ukuguqulwa kwama-multi-pass, imisebenzi enengqondo, futhi ekugcineni kuya ekugayweni kwe-cryptographic okuhlanganisiwe.
