Golang WebAssembly AES256 + Diffie Hellman

This code is a golang web assembly module which enabled AES256 encryption and Diffie Hellman handshakes.

Functionality

• Diffie Hellman P512 curve Handshakes + Key generation
• AES256 Encryption / Decryption
• WASM status check function
• Error handling
• WASM shutdown function
• WASM Panic test function

Building the WASM

$ GOOS=js GOARCH=wasm go build -o  wae.wasm

Examples

For example you can look at the index.html inside the "example" folder. You can also run the "server.go" file to spawn a temp webserver for testing.

$ cd example
$ go run .

Diffie Hellman Handshakes

This module can be used to handshake with a server or another user in whichever system you are developing.
Each back-and-forth handshake will consist of two "one-time-key" requests each one having their own UUID.

type OTK_REQUEST struct {
	X     *big.Int
	Y     *big.Int
	AUUID string
	BUUID string
}

These UUIDs are used to indentify matching handshake requests.
If you are handshaking with a server you can copy the "OTK_REQUEST" struct or make your own.
