So I tried aopenssl speed ecdsap256 ecdsap384And I got this : sign verify sign/s verify/s 256 bits ecdsa (nistp256) 0.0000s 0.0000s 80111.6 25480.5 384 bits ecdsa (nistp384) 0.0002s 0.0003s 6581.5 2886.0Wowsie I haven't expected to see that ecdsap384 is such a massive crash on performances than ecdsap256… :nkosweat:
