Note that this code was refactored quite heavily, and now lives in its own verification module. It lives here at the moment: https://github.com/andj/openvpn-ssl-refactoring/blob/master/ssl_verify.c . The verification code is called from key_method_2_write and key_method_2_read, in ssl.c (https://github.com/andj/openvpn-ssl-refactoring/blob/master/ssl.c). Adriaan
