[GNU Crypto] How to replace Sun JCE+BouncyCastle with GNU JCE+BouncyCastle?

[Kevin Smith]

Greetings all!

We have an app that currently uses BouncyCastle through the standard Sun 
JCE interface. We would like to switch to gnu-crypto, but we need some 
algorithms that the gnu-crypto JCE provider doesn't support, so we still 
want to use BouncyCastle as the provider.

I have put the gnu crypto jars (javax-crypto and javax-security) earlier 
in the classpath than the JRE versions. I have tried it with and without 
gnu-crypto in the classpath. The app builds, but when I try to run it I 
get this exception:

java.lang.SecurityException: class 
"org.bouncycastle.asn1.ASN1EncodableVector"'s signer information does 
not match signer information of other classes in the same package

Is it a known limitation that only the gnu-crypto JCE provider can be 
used at this time? If so, that should probably be added to the docs. 
Otherwise, any suggestions or things I should try?

I'm not subscribed to the list yet, so please CC me with any replies.

Thanks much,

Kevin
