certificates and PKI question

-

hi all,

i trying better understand certificates , pki.

i totally understand how certificates work , totally understand how pki works have been doing reading morning certificates , pki think have got myself confused.

ok . . if go internet explorer > internet options > tools > content > certificates see number of tabs - personal - other people - intermediate certificate authorities - trusted root certificate authorities - can see lots of vendors certificates in list under trusted root certificate authorities. if go website such paypal (who secure , use certificate) certificate appear? downloaded computer or not? understand certificate holds public key not understand certificate , comes from?

why internet explorer hold certificates people verisign? thought verisign ca issue certificates people such paypal. don't quite understand why cas have certificates listed within interne explorer.

sorry if explanation isn't clear . . . can me understand above?

thanks

> example if go paypal , explorer bar turns green, can click , view cert explorer bar can see downloaded cert?

in web browser, obviously. downloaded memory , linked context handle current ssl sesstion. not installed anywhere.

> these certs in list?

these trusted root certificates , used establish trust certificates , chains.
