Kuhusu Kitengeneza UUID
UUID (GUID) nasibu za toleo la 4.
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 UUID
Kinachohesabu na wakati wa kukitumia
Kinazalisha UUID nasibu za toleo la 4 kwa wingi, kwa machaguo ya herufi kubwa au ndogo na mabano.
Jinsi ya kukitumia, hatua kwa hatua
- Chagua ngapi za kuzalisha.
- Chagua muundo.
- Nakili orodha.
Maana ya kila ingizo
- Ngapi – Inaanza at 5.
- Herufi kubwa – Enter your yangu figure.
- Bila vistari – Enter your yangu figure.
Jinsi ya kusoma matokeo
- 5 uuids – The headline answer. In the default example it reads 7746c7a8-885f-48f4-a834-02aa067a9c21.
Fomula
A v4 UUID has 122 random bits in the form 8-4-4-4-12 hex digits, with fixed version and variant bits.
Mfano uliofanyiwa kazi
With the starting entries (How many: 5), the calculator shows 5 uuids of 7746c7a8-885f-48f4-a834-02aa067a9c21.
Dhana na mipaka
- Generated on your device.
- The chance ya a collision ni practically zero.
Makosa ya kawaida
- Using UUIDs as secrets.
- Storing them as text in a large database when a binary type is available.
