Soo Saaraha Passphrase-ka Diceware oo Bilaash ah

Samee passphrases xasuusan iyo entropy sare leh adiga oo isku darsaya ereyo random ah. Tirada ereyada, kala-soocidda, iyo xarfaha waaweyn la habayn karo — wuxuu isticmaalaa random-nimo cryptographically secure ah.

Maxay tahay diceware? Weedhaha erayo random ah ee la xasuusan karo waxay leeyihiin entropy weyn waxayna ka fudud yihiin in la xasuusto marka la barbardhigo xaraf aan macno lahayn. Weedh 5-eray ah waxay leedahay entropy ka badan password 10-xaraf ah oo random ah oo isku dhafan xarfo iyo calaamado. Random-nimada oo dhan waxay ka timaaddaa crypto.getRandomValues() ee biraawsarkaaga. Erayo, weedho, ama xog kale lama diri karo meel.

Sida Ay U Shaqeyso

Sameynta erey-fure wuxuu gebi ahaanba ka socdaa biraawsarkaaga isagoo isticmaalaya crypto.getRandomValues ee API-ga Web Crypto — isla isha random-ka cryptographic-ka ah ee maamulayaasha password-ka iyo TLS-ku isticmaalaan. Liiska 1,296-ereyga EFF ee gaaban waxaa lagu daray gudaha bogga si toos ah, sidaa darteed codsi shabakadeed lama sameeyo intii wax la sameynayay.

1
Doorashada ereyada oo eex-la'aan ah
Booska erey kasta, crypto.getRandomValues wuxuu buuxiyaa buffer Uint32 lambar random ah oo hardware-ku taageero. Sampling diidan ayaa tuura qiyamka gooyi lahaa qaybinta, natiijadana waxay tilmaan ka noqotaa liiska 1,296-ereyga EFF ee gaaban — taasoo siinaysa sax ahaan 10.34 bits oo entropy ah erey kasta iyada oo aan eex modulo ah jirin.
2
Waxyaabo dheeraad ah oo ikhtiyaarka ah
Haddii aad shiddo beddelka lambarka, integer random ah oo 0–99 ah ayaa lagu doortaa isla hab-eex-la'aan ah waxaana lagu daraa sida chip gooni ah, oo ku daraya ilaa 6.6 bits. Weynaynta xaraf-koowaad ereyga kastaa waa go'an, entropy midna kuma darto, taasoo qalabku si cad u xusayo.
3
Muuqaal entropy iyo waqti-jab toos ah
Entropy waxaa loo xisaabiyaa erayadaCount × log2(1296), qalabkuna wuxuu u beddelaa lambarkaas waqti qiyaas ah oo jab isagoo isticmaalaya saddex nooc weerar oo la dooran karo: 10 isku day/ilbiriqsi (online xaddidan), 10 bilyan/ilbiriqsi (GPU offline), iyo 100 trilyan/ilbiriqsi (cluster weyn). Xisaabtu way cusboonaysiisaa isla markaad beddesho tirada ereyada ama ikhtiyaarrada.
4
Erey-dib-u-samayn kasta oo koobi ah
Gujinta erey kasta wuxuu ku beddelaa kaliya ereygaas mid cusub oo dhawaan la sameeyay — isla entropy, waxtar leh haddii aad rabto inaad ka bedesho hal erey oo aan macquul ahayn iyada oo aan la dib-u-sameyn erey-furaha oo dhan. Xariga ugu dambeeya waxaa lagu dhisaa kala-soocaha aad dooratay waxaana loo qoraa clipboard-ka via Clipboard API-ga caadiga ah.

Erey-furaha waxaa loo sameeyaa gudaha biraawsarkaaga isagoo isticmaalaya xogta ereyada ee si gudaha ah lagu daray — waxba server looma diro wakhti kasta.
