    • ECDH driver now supports Montgomery Curves specified with only an X coordinate

      Currently, Montgomery curves (specifically Curve25519) require a CryptoKey with both an X and a Y coordinate even though they should be able to function with only the X coordinate.

      This change requires

      • Updating of the top-level documentation to reflect this behaviour
      • Editing the code that currently zeros out the Y-coordinate
      • Changing the runtime length check of the CryptoKey length
