Is there an "On start decrypt listener"

[swaix]

I need a way to understand when the method decrypt starts.
Decryption seems to be very slow (I'm testing on a nexus 6p and it takes like 1 second to finish). I have to add a spinner in order to give to the user a feedback that something happens.

thanks for your support and sorry for bad english.

There is no such listener right now. A possibility would be to emit a value in onNext giving the status update. I'll think about adding something like this.
