We have a Java-based server that runs on W2K machine behind a firewall (Red
Hat Linux 9 - iptables). Remote clients connect to the server via RMI, on a
specific port.
At this moment, the firewall is configured to accept connections only from

Is it possible to have multiple key entries in the keystore used by the
KeyManagerFactory when using the reference implementation?

Hye !
I struggle for two days now with Tomcat 5 BASIC authentication.
I read many posts about the problem but most of the people seem to
have a login window appearing. I don't :-(

I have a requirement to upgrade one of our datafeed applets that currently
uses TCP/IP to send and receive data to use HTTP posts and read the relevant
responses.
The problem is that we need to service 10s of thousands of clients, each of

I've got a system where a client requests some data. To protect the data,
they're encrypted with a symmetric session key (of length let's say 186
bit). The session key itself has to be encrypted with several different
public RSA keys, because the client has to prove that (s)he ...

Is there any java Provider for encryption with rsa/ecb/pkcs#1 for texts

Does anyone know whether an open source version of the keytool exists?
A quick search of comp.lang.java.* showed me a couple of things from
about five years back that looked kind of like what we're looking for,
but I'm too new to this stuff to be sure what I'm looking at.

I'm trying to work out how I can get my root certs into a format readable by
the BouncyCastle provider, and that seems to mean PKCS12. I have tried
exporting certs in base64 and feeding them into openssl, but openssl seems
to need the private key in order to generate PKCS12. Does ...
