This repository contains a very light wrapper around wolfSSL for GO, a server/client example, and some example wolfCrypt applications.
To use the wolfSSL go module, first build and install wolfSSL as shown below.
git clone https://github.com/wolfSSL/wolfssl
./autogen.sh
./configure
make
sudo make install
Then run the command below to build and install the wrapper module.
go get -u github.com/wolfssl/go-wolfssl
If building wolfSSL with a non-empty configure, you'll have to run the ./generateOptions.sh executable to customize go-wolfssl to the same feature set as wolfSSL. This executable will generate an options.go file that will keep go-wolfssl and wolfSSL in sync. generateOptions should be run any time you change your wolfSSL configure options.
Example: To use go-wolfssl without ECC, first build wolfSSL as shown below:
./configure --disable-ecc
make
sudo make install
Then go to the go-wolfssl directory and if the path to your wolfSSL directory is ../wolfssl, just run:
./generateOptions.sh
If you have a different path to your wolfSSL directory, run the executable with the right path:
./generateOptions ../files/wolfSSL
options.go is now generated and go-wolfssl can be run with ECC disabled!
The example .go files are located in the client and server directories.
To build the server, run :
cd examples/server
go build server.go
To build the client, run :
cd examples/client
go build client.go
NOTE: Make sure to run both the server and client from within their directories or change the certificate and key paths in the code so that the files are found.
See examples/README.md for details on building/running the other examples.
NOTE: If you have wolfSSL installed in a non-standard location, edit the CFLAGS and LDFLAGS specifications in the *.go source files to correspond to your custom installation path.
