Subject Re: tomcat 4.1.x with jdk1.4.2 ssl certificate(4096-key length) support - again
Date Thu, 10 Mar 2005 08:30:11 GMT
Bruce, thanks for response.

I know java has problem. Tomcat is here because I would like to have 
tomcat with SSL (with rsa key 4096 length support).
I installed unlimited JCE strength and problem stil exist.
Can anyone confirm "does Java 1.4 support 4096 RSA key size or only 2048".

Best regards

	Matej
