Kuhusu Kitengeneza PIN
Kitengeneza PIN nasibu: chagua urefu na idadi, na uepuke marudio na mfuatano ili PIN iwe vigumu kukisia.
Sehemu ya kitengo cha “Usalama na usimbaji” cha SmartCalcy. Kinaendeshwa kwenye kivinjari chako bila akaunti, kinatumia sarafu na vipimo vyako (vibadilishe juu ya ukurasa), na kinatoa makadirio kwa taarifa tu, kwa hiyo angalia mwongozo rasmi kabla ya kutegemea matokeo.
Jinsi ya kutumia Kitengeneza PIN
Kinachohesabu na wakati wa kukitumia
Kinazalisha misimbo nasibu ya PIN ya tarakimu 3 hadi 12, kwa chaguo la kuepuka mifumo rahisi kama 1234, 1111 au 2580. Kinatumia kizalishaji salama cha nasibu cha kivinjari chako na hakuna kinachotumwa popote.
Jinsi ya kukitumia, hatua kwa hatua
- Chagua urefu kwa tarakimu.
- Chagua idadi ya PIN unazotaka.
- Acha “Epuka marudio na mfuatano” ikiwa imewashwa kwa PIN zenye nguvu zaidi.
- Bonyeza “Tengeneza tena” ikiwa unataka seti nyingine, kisha nakili.
Maana ya kila ingizo
- Urefu – The Namba ya digits, from 3 hadi 12.
- Ngapi – From 1 hadi 100 PINs.
- Avoid repeats na sequences – Skips PINs such as 0000, 1234, 4321 na repeated pairs.
Jinsi ya kusoma matokeo
- PIN – The kwanza PIN, shown large, na a list ya zote ya them.
- Combinations – How many PINs ya that Urefu are possible.
Fomula
Each digit is a secure random number from 0 to 9. The number of possible PINs is 10^length, so 4 digits give 10,000 and 6 digits give 1,000,000. Weak patterns are rejected and redrawn.
Mfano uliofanyiwa kazi
A 6-digit PIN has 1,000,000 combinations, 100 times more than a 4-digit PIN.
Dhana na mipaka
- Rejecting patterns removes a few of the possible PINs, which does not meaningfully reduce strength.
- PINs are generated huko your browser na are not stored.
Makosa ya kawaida
- Using birthdays or the last digits of a phone number instead of a random PIN.
- Reusing one PIN kwa several cards au accounts.
- Storing a PIN on the card au baada ya your wallet.
Maswali yanayoulizwa mara kwa mara
Je, PIN ya tarakimu 6 ni salama zaidi kuliko ya tarakimu 4?
Ndiyo, ina michanganyiko mara 100 zaidi, ingawa kinachojalisha zaidi ni kikomo cha makisio yasiyo sahihi.
Je, PIN hizi ni nasibu kweli?
Ndiyo. Zinatoka kwenye kizalishaji cha nasibu cha kikriptografia cha kivinjari.
PIN zipi zinatumika zaidi?
1234, 1111, 0000 na miaka ya kuzaliwa. Zana hii huziepuka kwa chaguo-msingi.
Je, PIN inahifadhiwa?
Hapana.
