I offentliggjorte<\/a><\/noindex> i frie tilg\u00e6ngelige dumps af historiske snapshots med BSD 3 kode, findes der ogs\u00e5 en fil \/etc\/passwd<\/a><\/noindex> med hashene af Unix-grundl\u00e6ggernes adgangskoder. Da adgangskoderne er hashvet ved hj\u00e6lp af DES-metoden, som for moderne computere ikke udg\u00f8r et problem at kn\u00e6kke, har entusiaster fors\u00f8gt<\/a><\/noindex> at genoprette adgangskoderne, der blev brugt af Unix-grundl\u00e6ggerne.<\/p>\n

Adgangskoderne for n\u00e6sten alle Unix-grundl\u00e6ggere blev kn\u00e6kket<\/a><\/noindex> n\u00e6sten med det samme. For eksempel var Brian Kernighans adgangskode en let indtastelig kombination «\/. ,\/.,,», Dennis Ritchies adgangskode var «dmac», Kirk McKusicks — «foobar», og Steven Borns — «bourne». <\/p>\n

Undtagelsen var Ken Thompsons adgangskode. I 2014, efter flere dages beregninger, forblev adgangskoden ukn\u00e6kket. For nogle dage siden blev der foretaget<\/a><\/noindex> endnu et fors\u00f8g, og efter mere end 4 dages afpr\u00f8vning ved hj\u00e6lp af hashcat p\u00e5 et system med et AMD Radeon Vega64 grafikkort lykkedes det at finde adgangskoden (ydelsen til pr\u00f8vning var 930 millioner hashes per sekund). Adgangskoden viste sig at v\u00e6re «p\/q2-q4!». Skakelskere fastslog, at dette var begyndelsen p\u00e5 en r\u00e6kke skak\u00e5bninger<\/a><\/noindex> i i beskrivende notation.<\/a><\/noindex>Ken Thompson har bekr\u00e6ftet<\/a><\/noindex> denne antagelse.<\/p>\n
