Golang JSON Marshal/Unmarshal on struct containing byte arrays

I have a struct with various attributes that are byte arrays. For each, I generate some random bytes and I try to marshal the struct. However I can't seem to successfully unmarshal the struct. I suspect this may be due to how I am generating random bytes but I'm not sure how to pinpoint the issue here.

Your struct fields are unexported. – Oct 14 '17 at 01:10
@TimCooper it's in a single `main` package though. – Pandemonium Oct 14 '17 at 01:13

It doesn't matter. For the reflection library to properly work with the fields they must be exported, and `encoding/json` uses reflection. – Milo Christiansen Oct 14 '17 at 01:16
Ah I see, did a quick lookup on that and it seems to have fixed my issue -- couldn't find the linked question in any of my google queries earlier. Thanks! – Tony Situ Oct 14 '17 at 01:21
@TimCooper yes my bad. – Pandemonium Oct 14 '17 at 01:22
