Hi, I have a project which requires AES-ECB for iOS and Android. It would be great if you could implement this mode. Thanks!

from cryptography-kotlin.

Hey @dominikkv, could you please describe a use case for AES-ECB just in case?

from cryptography-kotlin.

Hi @whyoleg, in this project we communicate with a bike lock via BT LE. During the authentication process the lock sends us a challenge, which we have to decrypt, modify, and encrypt again, to send the result back to the lock.

Thanks for considering the implementation of AES-ECB!

Thanks @dominikkv!
I will add AES-ECB to plans, though, as this algorithm is some kind of "legacy/unsafe", I'm not sure yet, what will be the best way to show this when using the library.
Still, I will try to come up with something!

Hi @whyoleg, one idea would be to annotate the function / class with a "Unsafe to use" opt-in annotation: https://kotlinlang.org/docs/opt-in-requirements.html

from cryptography-kotlin.

Yeah, that't the simplest way here...
But there are some usability issues with opt-in:

• the declarations are still present in completion
• IDEA will allow to opt-in into this in a one click - not really convenient as AFAIK users are frequently ignoring what annotation say
• API reference will still have all those declarations in one place

On current moment I thinking about introducing of additional module for this, so that if it's REALLY needed it will be possible to add module and so use those algorithms.
But I'm not yet finalised design here, so, thanks for your comment!
