feat(interception): close remaining PR #157 compliance gaps
Full diff analysis against upstream's 50 commits revealed 8 functional
gaps after v5.0. These are detectable by conformance tests or detector
apps inspecting KeyMetadata authorizations and operation semantics.
KeyMetadata authorizations:
- Add 9 TEE-enforced tags (CALLER_NONCE, MIN_MAC_LENGTH, ROLLBACK_RESISTANCE,
EARLY_BOOT_ONLY, ALLOW_WHILE_ON_BODY, TRUSTED_USER_PRESENCE_REQUIRED,
TRUSTED_CONFIRMATION_REQUIRED, MAX_USES_PER_BOOT, MAX_BOOT_LEVEL)
- Fix CREATION_DATETIME to SOFTWARE security level via createSwAuth
- Add SOFTWARE-enforced date enforcement, USAGE_COUNT_LIMIT, UNLOCKED_DEVICE_REQUIRED
Symmetric key support:
- Generate AES/HMAC keys in software via javax.crypto.KeyGenerator
- GeneratedKeyInfo expanded with nullable keyPair + secretKey fields
- CipherPrimitive accepts java.security.Key for symmetric operations
- SoftwareOperation routes ENCRYPT/DECRYPT to secretKey when available
Operation compliance:
- beginParameters property replaces manual IV wrapping for GCM
- KeyAgreementPrimitive for ECDH AGREE_KEY operations
- handleCreateOperation wrapped in runCatching (crash prevention)
- SECURE_HW_COMMUNICATION_FAILED on software gen failure
Certificate patching:
- Import key cert chain + authorization patching in onPostTransact
- patchAuthorizations added to post-generateKey PATCH mode path
