# wavSteg

A command line interface based program for wav audio Steganography.

it uses an algorithm that I've developed in which there are 2 steps to encoding an wav file.

:mag_right: find closest ascii character in PCM data, and insert value to the corresponding index.

:pushpin: Mark the previous index

### Limitations And Encoding / Decoding times
Since the program stores the data linearly and depends on the previous encoded index, doing so makes it a whole lot more diffcult to
make the program multi-threaded which increases the compute time.
however, since the index is cached the encoding computation isn't relooping the entire PCM data, which makes it easier to compute.

### Installation
1. Install go-lang from offical website

```https://go.dev/doc/install```

2. build program
```go build wavSteg.go```

### Running the Program
1. Place .wav file to encode inside ```input``` folder.
2. Place text file(or any other file that you can read from) inside ```input``` folder.

```
Usage:
-audio string
Audio file name
-decode
Decode flag (default true)
-encode
Encode flag
-message string
Encode message with Command Line Interface message
-tfile string
Encode message with provided text file name

```

encoding example:
```
./wavSteg -audio=input/sample-file-2.wav -tfile=input/toEncode.txt -encode=true
```
```
./wavSteg -audio=input/sample-file-2.wav -message "hello world!" -encode=true
```
decoding example:
```
./wavSteg -audio=enc_file.wav -decode=true
```
Encoded audio and Decoded file will be saved to results directory.
