I am a new user to OpenSSL and I am trying to get our Payflow Pro account to accept transaction using XMLPay. I keep getting a certificate error: "Could not verify the first certificate" I am trying to send the transaction from X-Cart Shopping Cart Software with the following command: C:\OpenSSL\bin\openssl.exe s_client -connect test-payflow.verisign.com:443 -quiet < C:\path\to\xct956.tmp 2>C:\path\to\xct957.tmp I have tried adding "-CApath C:\path\to\payflow\cert", but this does not work either. Anybody have any ideas? Ken Vandegrift [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Web Administrator Sharis Mgmt. Corp
