-# Fuzzer for android.hardware.drm@1.4-service.clearkey
-
-## Plugin Design Considerations
-The fuzzer plugin for android.hardware.drm@1.4-service.clearkey is designed based on the understanding of the
-source code and tries to achieve the following:
-
-##### Maximize code coverage
-The configuration parameters are not hardcoded, but instead selected based on
-incoming data. This ensures more code paths are reached by the fuzzer.
-
-android.hardware.drm@1.4-service.clearkey supports the following parameters:
-1. Security Level (parameter name: `securityLevel`)
-2. Mime Type (parameter name: `mimeType`)
-3. Key Type (parameter name: `keyType`)
-4. Crypto Mode (parameter name: `cryptoMode`)
-
-| Parameter| Valid Values| Configured Value|
-|------------- |-------------| ----- |
-| `securityLevel` | 0.`SecurityLevel::UNKNOWN` 1.`SecurityLevel::SW_SECURE_CRYPTO` 2.`SecurityLevel::SW_SECURE_DECODE` 3.`SecurityLevel::HW_SECURE_CRYPTO`  4.`SecurityLevel::HW_SECURE_DECODE` 5.`SecurityLevel::HW_SECURE_ALL`| Value obtained from FuzzedDataProvider in the range 0 to 5|
-| `mimeType` | 0.`video/mp4` 1.`video/mpeg` 2.`video/x-flv` 3.`video/mj2` 4.`video/3gp2` 5.`video/3gpp` 6.`video/3gpp2` 7.`audio/mp4` 8.`audio/mpeg` 9.`audio/aac` 10.`audio/3gp2` 11.`audio/3gpp` 12.`audio/3gpp2` 13.`audio/webm` 14.`video/webm` 15.`webm` 16.`cenc` 17.`video/unknown` 18.`audio/unknown`| Value obtained from FuzzedDataProvider in the range 0 to 18|
-| `keyType` | 0.`KeyType::OFFLINE` 1.`KeyType::STREAMING` 2.`KeyType::RELEASE` | Value obtained from FuzzedDataProvider in the range 0 to 2|
-| `cryptoMode` | 0.`Mode::UNENCRYPTED` 1.`Mode::AES_CTR` 2.`Mode::AES_CBC_CTS` 3.`Mode::AES_CBC` | Value obtained from FuzzedDataProvider in the range 0 to 3|
-
-This also ensures that the plugin is always deterministic for any given input.
-
-##### Maximize utilization of input data
-The plugin feeds the entire input data to the module.
-This ensures that the plugin tolerates any kind of input (empty, huge,
-malformed, etc) and doesnt `exit()` on any input and thereby increasing the
-chance of identifying vulnerabilities.
-
-## Build
-
-This describes steps to build clearkeyV1.4_fuzzer binary.
-
-### Android
-
-#### Steps to build
-Build the fuzzer
-```
-  $ mm -j$(nproc) clearkeyV1.4_fuzzer
-```
-#### Steps to run
-To run on device
-```
-  $ adb sync data
-  $ adb shell /data/fuzz/${TARGET_ARCH}/clearkeyV1.4_fuzzer/vendor/hw/clearkeyV1.4_fuzzer
-```
