Hi, Thanks for your input. AFAIK registering these callbacks will result in locking the SSL datastructures internally by the OpenSSL whenever required. My question is since I've handled these in my application is it necessay for me to register these callbacks once again to the OpenSSL. I'm handling this in application becoz i've to save some more datas in the application scope from multiple thread access. So I've taken a lock and using the same lock I'm trying protect the SSL datastructures also. So I this case is it necessary to register once again into the openSSL.
