v1.1.0

Description

e4go v1.1.0 brings public key support to e4client, more flexibility and control over the storage of the client data, and some minor bug fixes and performance improvements.
See the upgrade instructions below to migrate from e4go v1.0.x

Improvements

e4go:

• Reworked client storage to allow more storage options than a file (such as memory, browser local storage...). The new storage interface is compatible with the generated bindings, see the updated README for an example implementation of an Android FileStore. (#35)
• Added SetC2Key command support and performance improvement by storing a precomputed shared key instead of recalculating on each calls (#36)

e4client

• Added public key mode support (#24)

Fixes and bugs

e4go

• SetIDKey command was rejecting Ed25519 keys (#39)
• Switched dependency from github.com/agl/ed25519/extra25519 to github.com/teserakt-io/golang-ed25519/extra25519 due to repository deprecation notice (#41)
• Typo fix (#38)

e4keygen

• E4 Keygen now truncate an existing output file when --force flag is used (#40)

Known issues and upgrade instructions

• Migrating to the new storage interface:

e4go <= v1.0.1

client, err := e4.NewClient(config, "./myClient.json")

e4go >= v1.1.0

saveFile, err := os.OpenFile("./myClient.json", os.O_CREATE|os.O_RDWR, 0600)
if err != nil {
	panic(err)
}
defer saveFile.Close()

client, err := e4.NewClient(config, saveFile)
