Robert:

> I cannot import self-signed certificates into a KeyStore using keytool. It
simply prints out the message "Signature not available". What do I need to do
to import a self-signed certificate? Attached is an example of a certificate
that I cannot import (I've tried a number of others, including RSA's). Thanks
in advance.

If the certificate that you are trying to import is signed
with RSA, you need to have an RSA provider installed
(remember that RSA is not provided by the default SUN
provider that ships with the JDK).

See

http://java.sun.com/products/jce/jce12_providers.html
for a list of JCA compliant providers that implement
the RSA algorithm.
