Telegram Passport Example

Generating a private key

First, use a console to generate a private key:

WARNING: Keep your private key SECRET!

openssl genrsa 2048 > private.key

Generating your public key

Then use the console to print the corresponding public key:

openssl rsa -in private.key -pubout

Use the /setpublickey command with @BotFather to connect this public key with your bot.

And then...

Configure your index.html with your

<div id="telegram_passport_auth"></div>
<script>
    Telegram.Passport.createAuthButton('telegram_passport_auth', {
        bot_id:       11223344, // place id of your bot here
        // abouto scope here: https://core.telegram.org/passport/#passportscope
        scope:        {data: [{type: 'id_document', selfie: true}, 'address_document', 'email'], v: 1}, 
        public_key:   '-----BEGIN PUBLIC KEY-----...', // place public key of your bot here
        nonce:        'ab2df83746a87d2f3bd6', // place nonce here 
    });
</script>
