Hi! I'm trying to run an application which uses a lot of crypto stuff and I ran into some problems. A friend of mine told me to try some tests, like this one: http://java.sun.com/j2se/1.4.2/docs/guide/security/jce/JCERefGuide.html#DH2Ex And actually it does not work with GNU Classpath. I get: $ cacao DHKeyAgreement2 Using SKIP Diffie-Hellman parameters ALICE: Generate DH keypair ... ALICE: Initialization ... java.security.spec.InvalidKeySpecException at gnu.javax.crypto.jce.sig.DHKeyFactory.engineGeneratePublic(DHKeyFactory.java:94) at java.security.KeyFactory.generatePublic(KeyFactory.java:219) at DHKeyAgreement2.run(DHKeyAgreement2.java:107) at DHKeyAgreement2.main(DHKeyAgreement2.java:54) Caused by: java.lang.NumberFormatException at java.math.BigInteger.<init>(BigInteger.java:156) at gnu.java.security.der.DERReader.readUniversal(DERReader.java:226) at gnu.java.security.der.DERReader.read(DERReader.java:165) at gnu.javax.crypto.key.dh.DHKeyPairX509Codec.decodePublicKey(DHKeyPairX509Codec.java:212) at gnu.javax.crypto.jce.sig.DHKeyFactory.engineGeneratePublic(DHKeyFactory.java:89) ...3 more Any ideas?
