# Generator
|
|
|
|
Generates a wav file with keyboard sounds matching the privided input string. Only supports a-z and spaces, and should at least contain 250 characters to gain a statistically significant sample.
|
|
|
|
```python3 ./generator.py <input>```

# Solver
|
|
|
|
Minimalistic solver example that samples the audio stream, and on detecting the start/end of sounds, calculates the average volume of that keystroke and maps it onto an arbitrary mono-alphabetic alphabet. The resulting "substitution cipher" can then be put through a solver to find the original text.
|
|
See `test.sh` for an example.

|
```python3 ./solver.py output.wav``` |
