Re: [iaik-jce] Internal error when verifying a signature

["Dieter Bratko" <Dieter.Bratko@iaik.at>]

From your classpath I see that you are using iaik_jce.jar. I donīt know if
you use an additional RSA supporting provider, and if the certificates in
your content info are RSA certificates, but if so, you should use
iaik_jce_full.jar or add rsa_rc4.jar.

However, if this will not solve the problem, you may send me your DER
encoded ContentInfo, so that I can look into the problem.
