Tests to verify importWrappedKey functionality.
- Build ASN.1 DER-encoded wrapped key material `SecureKeyWrapper`.
Import the wrapped key material. Test should create DER-encoded
wrapped key material and import the secure key successfully.
Imported key should be used perform crypto operation successfully.
- Build ASN.1 DER-encoded wrapped key material `SecureKeyWrapper` with
invalid AAD. Try to import the wrapped key material. Test should
create DER-encoded wrapped key material. Test should fail to import
the secure key with error code `VERIFICATION_FAILED`.
- Import wrapped AES key and use it for crypto operations. Test should
import wrapped key and user it for performing crypto operations
successfully.
- Import a key wihtout WRAP_KEY purpose and try to use it as wrapping
key while importing wrapped key. Test should fail to import wrapped
key with an error code `INCOMPATIBLE_PURPOSE`.
- Try to import wrapped key using non-existing wrapping key in Android
keystore. Test should fail to import wrapped key with an error code
`KEY_NOT_FOUND`.
