Added: jce/src/cryptix.jce.provider.util Group.java
Precomputed.java
Removed: jce/src/cryptix.jce.util Group.java Precomputed.java
Log:
- Moved cryptix.jce.util.Group and cryptix.jce.util.Precomputed to
cryptix.jce.provider.util. This allows DH and ElGamal to function
when cryptix-jce-api.jar is not in the CLASSPATH.
I'm too lazy for a repo-copy.
