Keystore 2.0: Revisit Key Parameters
key_parameters.rs provides an internal representation of key parameters
and conversion functions between the internal representation and both
the AIDL KeyMint key parameters and the persistent storage back end.
Previously, we had only the former conversion bootstrapped from a list
description of the key parameters. Now we have only a single list
from which all conversions and the KeyParameterValue enum itself are
bootstrapped.
In addition, the following improvements were made:
* convert_to/from_wire was replaced with the more idiomatic
implementation of From and Into traits.
* A new test is auto generated from the key parameter list verifying
that the associated union field of the keymint KeyParameterValue
matches the encoded tag type of the keymint Tag value.
Test: keystore2_test
