GopenPGP Wrapper Library

Download/Install

Manually git clone the repository into $GOPATH/src/github.com/ProtonMail/go-pm-crypto.

This library is meant to be used together with https://github.com/ProtonMail/crypto.

Using with Go Mobile

Setup Go Mobile and build/bind the source code:

Go Mobile repo: https://github.com/golang/mobile
Go Mobile wiki: https://github.com/golang/go/wiki/Mobile

1. Install Go: brew install go

2. Install Gomobile: go get -u golang.org/x/mobile/cmd/gomobile

3. Install Gobind: go install golang.org/x/mobile/cmd/gobind

4. Install Android SDK and NDK using Android Studio

5. Set env: export ANDROID_HOME="/AndroidSDK" (path to your SDK)

6. Init gomobile: gomobile init -ndk /AndroidSDK/ndk-bundle/ (path to your NDK)

7. Build examples:
   gomobile build -target=android #or ios

   Bind examples:
   gomobile bind -target ios -o frameworks/name.framework
gomobile bind -target android

   The bind will create framework for iOS and jar&aar files for Android (x86_64 and ARM).

Other notes

This project uses glide to setup vendors.

Interfacing between Go and Swift: https://medium.com/@matryer/tutorial-calling-go-code-from-swift-on-ios-and-vice-versa-with-gomobile-7925620c17a4.

If you use build.sh, you may need to modify the paths in it.
