Hi There, I am using axis2/c to develop a web service client application. I use openSSL to web service https/SSL communication. In order to avoid the patent issue for the portion of openSSL, I build the openSSL libraries myself using ./config no-idea no-mdc2 no-rc5. All is working fine as far as I am concerned, my client application can talk to web service server through https. Now my question is: What cypto algorith is actually used in the https/SSL communication? What is really turned off by using no-idea no-mdc2 no-rc5? If these things are not needed, then why they are there? Thanks much! Raymond
