Hi Crypto Experts,
Please pardon my ignorance regarding curve25519, but I ran into problems [*]
trying to recreate the sample certificate:
https://tools.ietf.org/html/rfc8410#section-10.2
It seems that the certificate is signed with a key intended for ECDH.
Question: is Java's "Signature" objec
What version of java are you using and what’s your command to generate the key
pair?
Thanks,
Max

Hi Max,
While waiting for JDK 15, I'm currently using JDK11 and BC but the question is
really about the Signature object specification.
KeyPairGenerator kpg = KeyPa
Is “Ed25519” what you need? It’s not available in JDK 11. See
https://bugs.openjdk.java.net/browse/JDK-8199231.

I know, that's why I wrote that I currently use BC (BouncyCastle).
My question is thus applicable to JDK 15. BC apparently rejects X25519
s
The RFC8410 author claims that the public key featured in the "self-issued"
certificate is NOT related to the signature key.
The answer to my question is thus (?) that "Signature" should (as BC does)
reject X25519 keys.
All is good :-)

In JDK 15, a Signature.getInstance("Ed25519”) would also reject a key generated
from KeyPairGenerator.getInstance("X25519”). It accepts a key from
KeyPairGenerator.getInstance("Ed25519”).
Thanks,
