Subject RE: How to find what encryption algorithm tomcat is using?
Date Wed, 25 Jan 2006 13:42:44 GMT
Vineesh,

I think you are right. 
I used the following code to find out the encryption algorithm in my
servlet,

 String cipherSuite = (String)
httpReq.getAttribute("javax.servlet.request.cipher_suite");
   if(cipherSuite != null){
    out.println("javax.servlet.request.cipher_suite is " + cipherSuite);
   }

I got the following result
javax.servlet.request.cipher_suite is SSL_RSA_WITH_RC4_128_MD5 

And I also used the RSA while generating a keypair for certificate. So
may be the same key-pair is used for encryption also.

Thanks for all your help.
Sangita

the key generation algorithm itself will be the encryption algorithm as
of my knowledge, otherwise the public and private keys do not match i
don know exactly from where they are determining the encryption
algorithm but in the key store the algorithm used will be ther regards
