Is it possible to use `process.hrtime` in Node-RED to measure an algorithm’s decryption time in microseconds?

Yes.

Depends.
It depends on how that algorithm is being run. If in a function node, then certainly you can. If between nodes in a flow, you still could but I don't know how meaningful it would be due to other overheads.
In a function node, simply "install" `node:process` in the function node's "Setup" tab with the name `process`. You can then simply use `process.hrtime` in your function code.
