# Keyboard Input Event Logger Summary
|
|
|
|
## Overview
|
|
|
|
This C program captures keyboard input events, resolves device names, and logs these events into a specified SQLite database `tikker.db`. It utilizes a custom library `sormc.h` for database management.
|
|
|
|
## Features
|
|
|
|
- **Key Event Mapping**: Maps keycodes to their respective characters for better representation.
|
|
- **Event Logging**: Logs key events with timestamps efficiently into the database.
|
|
- **User Configuration**: Allows device selection via a command-line option for targeted event capturing.
|
|
- **MIT License**: Allows free use, modification, and distribution of the software.
|
|
|
|
## Bugs and Issues
|
|
|
|
1. **Undefined Functions**: Missing definitions for `rargs_get_option_string`, `sormc`, and `sormq`, leading to potential undefined behavior.
|
|
2. **Device Resolution**: Uses `O_RDONLY` to open devices, which may need root access, potentially causing permission issues.
|
|
3. **Array Boundaries**: Access to `keycode_to_char` without bounds checking could lead to undefined behavior.
|
|
4. **Error Handling**: Lack of checks after using `snprintf`, `open`, and `ioctl`, leading to potential failures and bugs.
|
|
|
|
## Recommendations
|
|
|
|
- **Argument Parsing**: Use robust libraries for better flexibility and error management.
|
|
- **Signal Handling**: Implement graceful termination with proper file descriptor management.
|
|
- **Error Checking**: Add checks post `snprintf`, `open`, and `ioctl` to handle errors effectively.
|
|
- **Optimize Performance**: Reduce redundancy in `printf` statements for better efficiency.
|
|
|
|
## Positive Attributes
|
|
|
|
- Effectively maps keycodes to characters.
|
|
- Provides informative console output for ongoing events.
|
|
- Efficient database logging of key events.
|
|
|
|
## Potential Improvements
|
|
|
|
To enhance its robustness and user-friendliness, the program needs the implementation of missing functions and improved error-handling mechanisms.
|
|
|
|
## Alternative Open Source Tools
|
|
|
|
- **logkeys**: A Linux keylogger similar in function.
|
|
- **Keylogger (Python)**: Uses `pynput` for cross-platform keylogging.
|
|
- **Linux-dirty-injector**: Provides additional functionalities including keylogging.
