V novej verzii sa tie\u017e uskuto\u010dnil prechod na pou\u017e\u00edvanie k\u013e\u00fa\u010dov ed25519 ako predvolen\u00fdch namiesto RSA. Podpora star\u00fdch RSA k\u013e\u00fa\u010dov bola zachovan\u00e1, ale nov\u00e9 k\u013e\u00fa\u010de sa teraz bud\u00fa generova\u0165 pomocou algoritmu ed25519.

Okrem zmeny typu k\u013e\u00fa\u010dov predvolene v IPFS 0.7 bola pridan\u00e1 mo\u017enos\u0165 rot\u00e1cie identifika\u010dn\u00fdch k\u013e\u00fa\u010dov.

Pripom\u00edname, \u017ee v IPFS je odkaz na pr\u00edstup k s\u00faboru priamo spojen\u00fd s jeho obsahom a obsahuje kryptografick\u00fd hash obsahu. Adresu s\u00faboru nie je mo\u017en\u00e9 n\u00e1hodne premenova\u0165, m\u00f4\u017ee sa zmeni\u0165 len po zmene obsahu. Rovnako nie je mo\u017en\u00e9 upravi\u0165 s\u00fabor bez zmeny adresy (star\u0161ia verzia zostane na p\u00f4vodnej adrese, zatia\u013e \u010do nov\u00e1 bude dostupn\u00e1 na inej adrese, preto\u017ee sa zmen\u00ed hash obsahu s\u00faboru). Vzh\u013eadom na to, \u017ee identifik\u00e1tor s\u00faboru sa men\u00ed pri ka\u017edej zmene, aby sa ka\u017ed\u00fdm razom nemuseli posiela\u0165 nov\u00e9 odkazy, poskytuj\u00fa sa slu\u017eby na priradenie trval\u00fdch adries, ktor\u00e9 zoh\u013ead\u0148uj\u00fa r\u00f4zne verzie s\u00faboru (IPNS<\/a><\/noindex>), alebo na priradenie pseudonymu podobne ako v tradi\u010dn\u00fdch FS a DNS (MFS<\/a><\/noindex> (Mutable File System) a DNSLink<\/a><\/noindex>). <\/p>\n

Podobne ako v BitTorrent, \u00fadaje sa priamo ukladaj\u00fa na syst\u00e9moch \u00fa\u010dastn\u00edkov, ktor\u00ed si vymie\u0148aj\u00fa inform\u00e1cie v re\u017eime P2P, bez viazania na centralizovan\u00e9 uzly. Ak je potrebn\u00e9 z\u00edska\u0165 s\u00fabor s konkr\u00e9tnym obsahom, syst\u00e9m n\u00e1jde \u00fa\u010dastn\u00edkov, ktor\u00ed maj\u00fa dan\u00fd s\u00fabor a poskytne ho z ich syst\u00e9mov po \u010dastiach v nieko\u013ek\u00fdch pr\u00fadoch. Po stiahnut\u00ed s\u00faboru do svojho syst\u00e9mu sa \u00fa\u010dastn\u00edk automaticky st\u00e1va jedn\u00fdm z bodov jeho distrib\u00facie. Na ur\u010denie \u00fa\u010dastn\u00edkov siete, na uzloch ktor\u00fdch je pr\u00edtomn\u00fd zauj\u00edmav\u00fd obsah, sa pou\u017e\u00edva<\/a><\/noindex> distribuovan\u00e1 hashov\u00e1 tabu\u013eka (DHT<\/a><\/noindex>). Pre pr\u00edstup k glob\u00e1lnej FS m\u00f4\u017ee IPFS pou\u017e\u00edva\u0165 protokol HTTP alebo by\u0165 namontovan\u00fd ako virtu\u00e1lna FS \/ipfs pomocou modulu FUSE. <\/p>\n
