Assalomu alekum hammaga!
Bir narsa soramoqchi edim.

1. Spring security boyicha, jwt bn oauth2 alohida narsami? Bazi proyektlarda ikkalasini ham ishlatishgan bazila, oauth2 manimcha swagger uchun.

2. Role, Permission degan narsala bor, bunda user rollari boladi va shu role ga tegishli permissionlar boladi, shunaqa holatda qurgan yahshimi proyektni yoki faqat role ozini ishlatib ketgan yahshiroqmi?

Agar permission ishlatilgan bolsa, frontga user login qilganda userga tegishli bolgan permissionlar listi keladi va shunga tegishli bolgan narsalani front tarafdan chiqarib beriladi, backend tarafda bolsa service larga @PreAuthorize degan anotatsiya bor shunga permission nomini berib ketilsa, shu permission qaysi userda mavjud bolsa keyin shu service ishlaydi aks holda dostup zapreshon deydi, agarda role ozi bn qilingan bolsa, shu holatda qanday yechim qilinadi?


Agarda kimdadur shu security boyicha qilingan proyekt bolsa berolasizlarmi? Manimcha kopchili tayyor ozini proyektidan olib

Assalomu alaykum. Men o'z dasturimda JWT tokendan foydalanayapman. Uning xavfsizligini ta'minlash uchun refresh token ham ishlatilgan. Lekin ba'zi joylardan Access tokenni sessionStoragega saqlayotganda shifrlash mumkin ekanini o'qidim. Tokenni sessionStoragega saqlayotgandan qanday shifrlash kerak? Shu yul xavfsizlik jihatdan yaxshimi?
