Dear All, Thank you Ger Hobbelt for your help.
I want to validate only the signature of the server certificate. For example in peer verification, ssl will check time of client system(6:28PM 23 Jan 2009) to Ca root certificate validity time after client hello process. Validity Not Before: Aug 1 00:00:00 1996 GMT Not After : Dec 31 23:59:59 2020 GMT If in our application code I don't want to validate with system Time To validity period of time(Not Before and Not After). I want to validate to signature of the server certificate. Can I validate to signature of server certificate. Please reply me. Thank you. Regards, --Ajeet Kumar Singh
