iphone - Can keychains in IOS be compared to DPAPI in Windows? -


on ios, looking api equivalent encrypt/decrpyt dpapi functions available on windows (with cryptprotect_local_machine flag not set).

the objective persist application data locally , making access restricted application only.

i've read keychain functionality seems dictionary has user-level access (unlocked during smartphone logon). application 1 has access information, like, typically, having own keychain.

any advice on this?

an app cannot access app's keychain entries in ios. in principle, it's if each app has own keychain.

in ios, application can access own keychain items, not items created other application.

however, see this post other keychain security concerns.
