java.security.InvalidKeyException: No installed provider supports this key: sun.security.rsa.RSAPublicKeyImpl

Hello!

I’m using an EV certificate from SSL.com. The latest code after the fix for #105 made some progress, but still goes wrong somewhere. The Yubikey blinks briefly, but then jsign fails with this:

$ ./jsign.sh --keystore /home/vadim/etoken.cfg  --alias "X.509 Certificate for PIV Authentication" --storetype YUBIKEY --storepass $PASS  --tsaurl http://ts.ssl.com --tsmode RFC3161 nxproxy.exe
Adding Authenticode signature to nxproxy.exe
jsign: Couldn't sign nxproxy.exe
