I am wondering if a certificate can have more than 1 common name? If it
can, when we install such certificate on say a web server, is the
webserver domain name only supposed to match one of the common names?
Thanks

Our test network does not have a DNS - we access the machines by their
IP addresses.
One of the servers needs to provide HTTPS connectivity so I generated a
certificate for it using the IP address as the Common Name.

IBM's java (JDK 1.4.2) does not let encryption of data using a private key?
Is this is a standards restriction or is this IBM's implementation
restriction? I am wondering why this should be disallowed
Thanks,

I've done a bit of testing with the J2SE 5.0 timestamp support and jarsigner:
VeriSign's timestamp service implementation does NOT work with
Sun RFC 3161 implementation of timestamp.
The following test service (i.e. TSA cert NOT included in most trusted CA stores)

Is it possible to add extra certificate(s) to the pkcs7 signature blob in
a signed JAR archive?
This may be necessary in some cases .. for example VeriSign
issuing code-signing certificate via an INTERMEDIATE CA

I received a certificate issued by Verisign and imported in my Keystore
and I can successfully sign the applet.
But I *also* need to be able to export the certificate to a file so
that it can be integrated with the build process. I am unable to do

Given below is my code for DES encryption using JCE. The process of

Does anyone know how to encrypt a secret key with a public key algorithm
to transmit it to another computer securely. Have tried using RSA and
have had no look in the following code:
public byte[] encryptSessionKey(SecretKey sKey, PrivateKey pKey, String

Hi;
Can someone point me to some simple yet affective tutorials on
encrypting a string.

What is the difference b/w these two approaches of getting a
SSLSocketFactory..
In Weblogic 7.0sp4 it seems that only if you go thru the SSLContext
will it setup the trusted CA certificates correctly.

I'm trying to get an application to work over Web Start, and this
application makes use of third-party jars. Some of these jars contain
only a manifest which in turn specifies a classpath. I need to sign
these jars for use with my app.

I have written a applet that reads and writes data from a database. I
initially wrote the application to connect to a MYSQL database and
everything ran fine. I then changed the className and connect strings
for oracle and tested it with 'all permissions' on. works fine.
