that means, I can publish my app even though I build it in Kodular with min API-20 or 21 etc… ?

#47

Yes you can.Google has nothing to do with your app’s min api.

You can share the Key with your friend if you have Generated a new one.

#51

…how? That’s my question. How do I share the key?

#52

Go to Settings>Key There you can paste your friend’s key, Share your Key, Reset to Default Key and generate a new random Key.

#53

But then someone can compromise your account and see the key :joy:

jk

#54

I don’t understand

#55

How? That’s the biggest problem with your app. How are the keys supposed to be shared? By using symmetrical encryption for messages, the app offers effectively zero security.

How?

If you encrypt a message with a key called “1” and you share the encrypted message with your friend. If the friend tries to decrypt the message. The Output will be empty. He/She needs to put the “1” Key in their Key option to see the message that you created.

#57

How will I let them know my key?

#58

By Sharing in Whatsapp or SMS to them…

#59

Oops, looks like security has gone out of the window.

How? In which way…You are not understanding what I am telling.

#61

Then why am I not using WhatsApp (which offers better security)?

Consider this:
My friend knows my key.
We have a fight.
He leaks my key.
Everyone can read my messages now.

Or even:
Friend has key —> Friend can read all my messages.

I created a encrypted message and I want you to see the message. If I share the key with you. How that is not secure.

#63

You can generate a new one.

e.g If you friend knows your password and email. You had a fight. What happens if he leaks

e.g Your friend knows your secret. You had a fight. What happens if he leaks

e.g Your friend knows you have a GF. You had a fight. What happens if he tells to your father…

First Tell answer to this @Kanishka_Developer
