Hi, How do you encode/decode base64 in common code ? You go down to the android/ios specific sourceset ? I found that but it's seems forgotten https://github.com/Kotlin/kotlin-examples/pull/90

There is no common base64, the easisest solution is use platfrom specific library + expect/actual

You can try this solution: https://discuss.kotlinlang.org/t/kotlin-native-base64-en-decoder-code/10043

Krypto library has a pretty simple base64 impl: https://korlibs.soywiz.com/krypto/ https://github.com/korlibs/krypto/blob/master/krypto/src/commonMain/kotlin/com/soywiz/krypto/encoding/Base64.kt

A bit late, but yeah I used krypto and it's working fine 🙂
