IIUC, you want the value of every list element that is named "sha" and
that name will only apply to atomic objects.
If so, this should do it.

> shas <- unlist( input, use.names=FALSE )[ grepl( "sha", names(unlist(input)))]
> input[[67]]$content[[1]]$sha
[1] "58cf43ecdc1beb7e1043e9de612ecc817b090f15"
> which(input[[67]]$content[[1]]$sha == shas )
[1] 194
