I have a ktor setup with JWT authentication, and i have my own version of RSA algorithm overriding sign and verify.
When minify is enabled in android project, RSA algorithm's sign is called, but not the verify.
It works fine when minify is disabled. I have added --keep for all the related classes in proguard, but still it doesn't work.
When the api is hit, Unauthorized 401 is returned.
any idea?

-keep class com.fasterxml.jackson.core.type.TypeReference { *; }
Some where in JWT init/decode it failed.
After adding this along with -keep class com.auth0.jwt.** { *; } , it is sorted out.
