# Custom IO Callback Example
|
|
|
|
This is an example to demonstrate how the custom IO callbacks can be used to
|
|
facilitate a TLS connection using any medium. Here we chose the medium: "File System".
|
|
|
|
Other transports might be:
|
|
* USB Serial connection
|
|
* Bluetooth
|
|
* RFID
|
|
* Wifi
|
|
* Ethernet
|
|
|
|
These examples use the wolfSSL Custom IO Callbacks to read and write to the file
|
|
system and perform a successful handshake.
|
|
|
|
Building the examples:
|
|
|
|
From the wolfssl directory:
|
|
```
|
|
./configure --enable-debug
|
|
sudo make install
|
|
```
|
|
|
|
**NOTE:** Debug was enabled in case a user wishes to use the verbose flag to see
|
|
what is happening in real time:
|
|
|
|
From the file-server directory:
|
|
```
|
|
make
|
|
```
|
|
|
|
From the file-client directory:
|
|
```
|
|
make
|
|
```
|
|
|
|
Usage examples:
|
|
|
|
From the file-server directory:
|
|
./start-server
|
|
./start-server -v
|
|
./start-server -verbose
|
|
|
|
From the file-client directory:
|
|
./start-client
|
|
./start-client -v
|
|
./start-client -verbose
|
|
|
|
(-v and -verbose accomplish the same thing)
|
|
|
|
## SCRIPTS
|
|
|
|
The scripts provided attempt to make testing easier.
|
|
|
|
* file-server/check.sh
|
|
- starts the server in a background shell and runs the client
|
|
|
|
USAGE:
|
|
./check.sh
|
|
./check.sh -v
|
|
./check.sh -verbose
|
|
|
|
* file-client/clean-io-files.sh
|
|
- If something happens and there is leftover junk in the io files run this
|
|
script to quickly cleanup before next round of testing.
|
|
|
|
USAGE:
|
|
./clean-io-files.sh
|
