Need help to investigate how to create MTPROTO keys from usage example

[rglitchard]

Hello, @ololosha228. Thanks a lot for this library, can you please clarify how I can generate mtproto keys from your example?

func main() {
	keyfile := "/home/r0ck3t/go/src/github.com/xelaj/mtproto/keys/keys.pem"
	TelegramPublicKeys, err := keys.ReadFromFile(keyfile)
	dry.PanicIfErr(err)

I can't figure out how to generate this? Should I use the guide on the official documentation link: https://core.telegram.org/mtproto/auth_key or is there another way to do this? thanks

Hey @rglitchard, thanks for creating issue!

You can get RSA keys from here. Just save all public keys of your app into single file, and add path in configs.

To be honest, you need just first RSA public key, i don't know yet, what the purpose of other keys. but i think they are need to make requests to telegram CDNs or something like this. Just save ALL keys, we'll update this lib when we understand, why do we need other public keys)

Also, I suppose to add ENV files to the project. For example, if I changed the PATH into .pem keys, they otherwise already hardcoded in init() function on the telegram/common.go:

func init() {
	keyfile := "~/go/src/github.com/xelaj/mtproto/keys/keys.pem" // HERE IS CHANGE TO os.Getenv("MTPROTO_KEYS_PATH")
	TelegramPublicKeys, err := keys.ReadFromFile(keyfile)
	dry.PanicIfErr(err)
	choosedKey := dry.RandomChoose(dry.InterfaceSlice(TelegramPublicKeys)...).(*rsa.PublicKey)

	_ = choosedKey
}

If you agree with my idea, I can make the PR

@rglitchard oh crap, i supposed that i fixed it already)))

enviroments are bad in vendor libs, but idea is good. Also, check out this branch, i'll soon merge it into master, it has multiple fixes of client, and has NewClient constructor, you can add path in params
