Add HPKE benchmarks #434

Closed chris-wood closed 1 year ago

chris-wood commented 1 year ago

These benchmarks let one quickly compare the cost difference between two different HPKE ciphersuites (KEM, KDF, AEAD).

Here's a sample of the output when running the benchmarks (go test -bench=.) in the HPKE directory:

✗ go test -bench=.

Bit ad hoc, but fine by me.

Is there a better approach we should take?
