Hi Lukas,
finally we are now testing again our setup with the latest Rebex-Version + latest development with our IoT-device.
Unfortunately we receive some handshake error. See Rebexlog below.
We also did some trace with WireShark. One thing we noticed, is that maybe some signature algorithm is missing. We do need so something for ED25519, but only those are available:
Extension: signature_algorithms (len=18)
Type: signature_algorithms (13)
Length: 18
Signature Hash Algorithms Length: 16
Signature Hash Algorithms (8 algorithms)
Signature Algorithm: rsa_pkcs1_sha256 (0x0401)
Signature Algorithm: ecdsa_secp256r1_sha256 (0x0403)
Signature Algorithm: rsa_pkcs1_sha384 (0x0501)
Signature Algorithm: ecdsa_secp384r1_sha384 (0x0503)
Signature Algorithm: rsa_pkcs1_sha512 (0x0601)
Signature Algorithm: ecdsa_secp521r1_sha512 (0x0603)
Signature Algorithm: rsa_pkcs1_sha1 (0x0201)
Signature Algorithm: ecdsa_sha1 (0x0203)
We are following the approach mentioned here for integration:

Is there anything additional to consider? Do you have some extra advice, how the support for ED25519 can be enabled?
