Module ecdh

ECDH

Depending on the platform and available features the most efficient implementation is chosen.

x25519

For x25519 the portable HACL implementation is used unless running on an x64 CPU with BMI2 and ADX support. In this case the libjade implementation is used.

P256

For P256 the portable HACL implementation is used.
