Remove ENCRYPT/VERIFY from KeyUsage mapping to match Kotlin behavior.
Document BasicConstraints and SKI suppression via rcgen NoCa default.
Fix rotating log off-by-one that kept one extra backup file. Handle
BMPString (UTF-16BE) and VisibleString in X.500 DN parser.
Builds v3 leaf certificate with attestation extension and KeyUsage,
signs with keybox private key via rcgen 0.13.2. Assembles full chain
(leaf + keybox intermediates + root). Supports EC and RSA keybox
signing keys. Uses rcgen's signed_by() with a synthesized issuer
Certificate, no manual DER fallback needed.
Multi-output logging via tracing: /dev/kmsg for logcat, rotating file
appender (512KB, 3 files), stderr for debug. Diagnostic ZIP dump with
log files and TEE status snapshots. Verbose toggle via JNI flag or
.verbose marker file.
DER encoder for Android KeyMint attestation extension (OID
1.3.6.1.4.1.11129.2.1.17). SecurityLevel and VerifiedBootState as
ENUMERATED, EXPLICIT context-specific tagging with long-form for
tags >= 31, sorted AuthorizationList fields, RootOfTrust with
BOOLEAN TRUE=0xFF, SET OF INTEGER with DER sort, DO_NOT_REPORT
sentinel omission.
EC keygen now returns proper SPKI DER instead of raw point bytes.
RSA keygen uses caller-supplied exponent via new_with_exp() and
validates key size to 2048/3072/4096. Keybox parser extracts leaf
subject DN (not issuer). Added AttestKey=7 to KeyPurpose. Realigned
error variants with spec.
Splits concatenated DER cert chains into individual certificates,
extracts leaf issuer DN and notAfter via x509-cert crate. Handles
multi-byte DER length encoding (0x81-0x84).
Cargo.toml with 16 dependencies per build spec, error types with
From impls for all upstream error types, CertGenParams mapping the
full JNI config contract, EC/RSA key generation via ring and rsa crates.
Compiles clean for aarch64-linux-android via cargo-ndk.
TrickyAddon fetches Pixel bulletin dates for boot/vendor but system=prop
resolves to the real device prop, creating a cross-component date mismatch
on non-Pixel devices. Force all three through the same prop resolution path.
Sliding window limits each UID to 2 hardware generateKey calls per
30s burst window with max 2 concurrent. Overflow falls back to
software cert generation.
importKey post-hook retains patched chains instead of full eviction,
preventing detectors from using generate-then-import to bypass
attestation patching. getKeyEntry serves retained chains for imported
keys that overwrote attested aliases.
Some upstream keybox sources inject HTML comments inside PEM
certificate blocks. BouncyCastle's PEMParser chokes on these
non-base64 lines, silently failing to load the keybox.
Filter lines starting with <!-- in trimLines() before the content
reaches the PEM parser.
When a config file is deleted, the event handler sets file=null but
then force-unwraps it with file!! in the when block, crashing the
FileObserver thread. All subsequent config change notifications are
silently lost.
Replace force-unwrap with safe call, log a warning on deletion.
Fork-based supervisor ensures the interceptor process survives crashes.
pingBinder() liveness check on pre-transact returns DEAD_OBJECT to
callers when interceptor is down, preventing real TEE state from leaking
during the restart window.
action.sh clears persistent key storage via KSU Action button.
uninstall.sh kills daemon processes and removes module artifacts while
preserving target.txt and keybox configuration.
