## Key generation time
Generating EC keys is almost instant. RSA keypair generation takes some time, specially for `2048` and `4096` bits.

## Driver
Pico HSM uses the `sc-hsm` driver provided by [OpenSC](https://github.com/OpenSC/OpenSC/ "OpenSC") or the `sc-hsm-embedded` driver provided by [CardContact](https://github.com/CardContact/sc-hsm-embedded "CardContact"). This driver utilizes the standardized PKCS#11 interface to communicate with the user and it can be used with many engines that accept PKCS#11 interface, such as OpenSSL, P11 library or pkcs11-tool.
