I have created my X25519 pub/priv keypair with:
openssl genpkey -algorithm X25519\
And displays properly with:
openssl pkey -in $dir/private/$clientemail-X.key.$format -text -noout
So now to make the csr with:
openssl req -config $dir/openssl-intermediate.cnf\
-key $dir/private/$clientemail-X.key.$format \
-subj "$DN" -new -out $dir/csr/$clientemail-X.csr.$format
which is what I used for ED25519 client certs. But I get an error:
routines:EVP_PKEY_sign_init:operation not supported for this
I can't figure out from my config file why this error. and googling the
error has not helped. yet.
Can someone point me to what I am missing?
Oh, and I am ASSuMEing that a CA cert of ED25519 signs an X25519 client
cert. Haven't found instructions on this, but it seems reasonable...
