Z\u00e1kladn\u00ed, ale bezpe\u010dn\u00e9 heslo, lze slo\u017eit pom\u011brn\u011b snadno jako motiva\u010dn\u00ed v\u011btu typu: \u201eDnes je venku kr\u00e1sn\u011b.\u201c. (I kdy\u017e pr\u0161\u00ed, chce se mi dodat.)<\/p>\n

V j\u00e1dru t\u00e9to v\u011bty je mnoho obdob a variac\u00ed, se kter\u00fdmi se setk\u00e1v\u00e1me v\u00a0p\u0159ekladatelsk\u00e9m sv\u011bt\u011b i v CAT syst\u00e9mech<\/a> a sah\u00e1m si k nim pro vysv\u011btlen\u00ed terminologie, pam\u011bt\u00ed, separ\u00e1tor\u016f i principu po\u010d\u00edt\u00e1n\u00ed shody segment\u016f.<\/p>\n

Toti\u017e pokud pou\u017eijeme b\u011b\u017enou v\u011btu popisnou: \u201eDnes je kr\u00e1sn\u011b.\u201c a v\u011btu tonalitou sp\u00ed\u0161e zvolac\u00ed: \u201eDnes je kr\u00e1sn\u011b!\u201c, tak tyto dv\u011b v\u011bty nejsou pro CAT syst\u00e9my stejn\u00e9. R\u016fznost separ\u00e1tor\u016f, v tomto p\u0159\u00edpad\u011b rozd\u00edl te\u010dky a vyk\u0159i\u010dn\u00edku, je v\u00fdznamn\u00e1 kategorie mo\u017en\u00fdch chyb. Obsah sd\u011blen\u00ed v\u011bty je v\u0161ak stejn\u00fd.<\/p>\n

Kdy\u017e pou\u017eijeme v\u011bty \u201eDnes je kr\u00e1sn\u011b.\u201c a \u201eDnes bylo kr\u00e1sn\u011b.\u201c, je zm\u011bna cel\u00e1 jedna t\u0159etina obsahu sd\u011blen\u00ed. Zm\u011bna tam je, i kdyby slova \u201eDnes\u201c a \u201ekr\u00e1sn\u011b\u201c byla terminologick\u00e1, shoda v\u011bt bude vykazovat v\u00fdznamn\u00fd pokles a\u017e na m\u00edru pouh\u00e9 podobnosti.<\/p>\n

Dal\u0161\u00edm mo\u017en\u00fdm rozvojem v\u011bty je p\u0159idat do v\u011bty m\u00edsto. Tedy p\u0159\u00edkladem porovn\u00e1n\u00ed dvou v\u011bt vyjad\u0159uj\u00edc\u00edch v\u00fdznamn\u00fd vzdech: \u201eDnes je venku kr\u00e1sn\u011b!\u201c a \u201eDnes je tam stra\u0161n\u011b.\u201c.<\/p>\n

Co to m\u00e1 spole\u010dn\u00e9ho s tvorbou u\u017eivatelsk\u00fdch hesel?<\/h4>\n

Princip je obdobn\u00fd. Pokud pou\u017e\u00edv\u00e1te heslo \u201eH0nz@\u201c a \u0159\u00edk\u00e1te si, jak jste na syst\u00e9m vyzr\u00e1li… ehm.

Mus\u00edte j\u00edt v\u00edce do detailu, nap\u0159\u00edklad je sofistikovan\u011bj\u0161\u00ed jako heslo pou\u017e\u00edt v\u011btu v\u00a0podob\u011b popisn\u00e9ho d\u011bje.<\/p>\n

Pokud pou\u017e\u00edv\u00e1te vygenerovan\u00e1 hesla, taky spr\u00e1vn\u011b, jsou velmi bezpe\u010dn\u00e1.

Zkuste sv\u00e9 jednodu\u0161\u0161\u00ed heslo upravit razantn\u00ed prom\u011bnou, pou\u017eijte v\u011btu popisnou a pozm\u011b\u0148te n\u011bkter\u00e9 znaky<\/strong>. Pro p\u0159\u00edklad pou\u017eijeme zase v\u011btu \u201eDnes je venku kr\u00e1sn\u011b!\u201c.<\/p>\n

Heslo typu \u201ednesjevenkukrasne!\u201c u\u017e je mnohem lep\u0161\u00ed. Varianta zm\u011bny je nap\u0159\u00edklad: \u201eDnesJeVenkuKrasne,\u201c tedy prvn\u00ed p\u00edsmena velk\u00e1, anebo m\u016f\u017eeme odli\u0161it jednotliv\u00e9 souhl\u00e1sky a\u00a0samohl\u00e1sky: \u201eDNeSJeVeNKuKRaSNe!\u201c. Na za\u010d\u00e1tek u\u017e je takov\u00e9 heslo lep\u0161\u00ed, dokonce obsahuje speci\u00e1ln\u00ed znak \u201e!\u201c, kter\u00fd se cen\u00ed, ale machr\u016fm chyb\u00ed nav\u00edc i \u010d\u00edsla (ne nadarmo se dnes u v\u011bt\u0161iny platforem takov\u00e1 kombinace znak\u016f po u\u017eivateli p\u0159\u00edmo vy\u017eaduje).<\/p>\n

O t\u0159\u00eddu bezpe\u010dn\u011bji funguje heslo typu: \u201eDN3SJ3V3NKuKR@SN3!\u201c toto heslo u\u017e spl\u0148uje vysok\u00e9 po\u017eadavky.

Prakticky opravdu slo\u017eit\u00e9 heslo na prolomen\u00ed, a to u\u017e mus\u00ed b\u00fdt o prolomen\u00ed va\u0161eho \u00fa\u010dtu z\u00e1jem kv\u016fli pot\u0159ebn\u00e9mu v\u00fdpo\u010detn\u00edmu v\u00fdkonu, by tak mohlo vypadat takto: \u201eDN3SJeV3NKuKR@SNe!\u201c.<\/p>\n
