x25519 key usage

[dev-area]

hi
i built the new 4.2-eddsa1 and loaded it to the board

next , using pico-hsm-tool i initialized and generated x25519 key pair:

$ python3 pico-hsm-tool.py initialize
$ python3 pico-hsm-tool.py keygen x25519

Pico HSM Tool v1.14

How can i use this key (opensc-tool/openssl/pico-hsm-tool/....) to sign and verify
thanks

x25519/x448 are not Edwards curves (Ed25519 or Ed448).

pico-hsm-tool does not provide support for Edwards curves. I'll make a commit.

The way to sign is the same as other keys, nothing special is required.

f450279 adds support for Edwards curve generation.
