* Update unit tests to use keymaster2 interface.Shawn Willden2016-01-261-12/+13
| | | | | | | We no longer test the keymaster1 interface. That's okay, because it will be gone shortly. Change-Id: Id30c2fcda5d535165a0081a783b2252c112e5474
* Fix pass-through of deletion on wrapped KM0 and KM1.Shawn Willden2015-11-251-0/+4
| | | | | | | | | | SoftKeymasterDevice was incorrectly directly sending deletion requests to wrapped hardware. In some cases the key blob passed in by SoftKeymasterDevice is a hardware blob encapsulated by a wrapper, and we need to remove the encapsulation before passing it on.

* Do digesting, and sometimes padding, in SW when HW doesnt.Shawn Willden2015-08-131-1/+9
| | | | | | | | | | | | | | | | | | | | The keymaster1 specification only requires HW modules to implement SHA256 out of the list of keymaster1 digest modes. That would force many keys to be software only, and would break legacy scenarios. This change uses SoftKeymasterDevice to front keymaster modules that don't implement the full suite of digests, quietly inserting KM_DIGEST_NONE and KM_PAD_NONE into key generation/import requests when necessary, then performing the digesting, and sometimes padding, in software, then delegating crypto operations to the hardware. This is only done for RSA and EC keys. Software digesting isn't possible for HMAC or AES-GCM keys. Note that this is not the complete fix for the bug. Some changes in keystore are also required, coming in another CL. Bug: 22529223 Change-Id: I740572eb11341fb0659085309da01d5cbcd3854d
* Add support for KM_TAG_MIN_MAC_LENGTH.Shawn Willden2015-07-161-2/+2
| | | | | | | | | | HMAC and AES-GCM keys must be bound to a mininum MAC/tag length at creation, and operations may not specify a length smaller than the minimum, or provide a length smaller than the minimum during verification. Bug: 22337277 Change-Id: Id5ae2f4259045ba1418c28e9de8f4a47e67fd433
