I'm trying to create a keystore using keytool with a keyalg ECC.
This should be possible according to Oracle. I quote:
Area: Tools
Synopsis: The
keytoolandjarsignertools now support the ECC algorithm in keypair generation and jar signing.RFE: 6870812
I'm using the 32-bit version 1.7.0_07, and I've tried keytool with -keyalg ECC, ECIES, ECDSA,... but I always get Cannot derive signature algorithm.
Am I using the wrong Java version? Am I using the wrong name for ECC?
I believe you have to install the unlimited strength policy for JCE to work with all algorithims. If you haven't done so already, it's at the bottom of this page: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Here is the source for the algorithm selection. The allowed values are
DSA,RSAandEC. These values are not documented anywhere as far as I can tell.
