hey i'm looking for best&amp;solid&amp;proof library/sdk for AES encryption, anything recommend in multiplatform project? usecase: encrypt/decrypt file in app folder.

Best is expect/actual or better, common interface + Platform implementations. That way you keep up with the latest and greatest security APIs in each platform. Otherwise, you will always be behind some library third party maintainer. Security is something you don't want to be in this position. Other stuff is fine, like a UI library and such, but not security.

Did you check this project? <https://github.com/whyoleg/cryptography-kotlin>

yes I've seen this one. im just skeptical in usage of thirdparty library for production usecase, especially when it's about security

I mean you did ask for a library, and libraries tend to be third-parties :slightly_smiling_face:
