Subject Re: tomcat 4.1.x with jdk1.4.2 ssl certificate(4096-key length) support - again
Date Thu, 10 Mar 2005 00:57:04 GMT
Having looked at this issue just reciently, I believe the root cause
of the problem is fact that your version of Java 1.4.2 is the exported
restricted version from SUN.  By going to JDK 1.5, you have
demonstrated that problem is not with tomcat, but with JAVA itself. 
Check out the section titled "How to Make Applications "Exempt" from
Cryptographic Restrictions" in "JavaTM Cryptography Extension (JCE)
Reference Guide"
