I did a quick test with my Android client to see if it works and RSA
keys look good so far. I am getting a request like:
NC9t8IkYrjAQcCzc85zN0H5TvwfAUDwYkR4j2ga6fGw=,RSA_PKCS1_PSS_PADDING,hashalg=SHA256,saltlen=digest
from the management interface. But I haven't found the right Signature
method from java yet to actually sign it correctly:
sig = Signature.getInstance(SHA256withRSA/PSS);
sig.setParameter(new PSSParameterSpec("SHA-256", "MGF1",
MGF1ParameterSpec.SHA256, 32, 1));
sig.initSign(privkey);
sig.update(data);
signed_bytes = sig.sign();
is what I expected to be the correct signature but the server complains
with OpenSSL: error:0407E068:rsa routines:RSA_verify_PKCS1_PSS_mgf1:bad
signature
I will have to figure out where this goes wrong.
With an EC key somewhere in that stack, EC/RSA gets confuse as there is
rsa_keymgmt_import/rsa_keymgmt_name in the stack and then later
ec_keymgmt_name. I haven't digged into that as it is getting late here.
