I am in the process of migrating our code from the 1.0.2 library to 1.1 and have run across a situation that I am struggling to reconcile: The existing code utilizes the verify_callback() function in order to perform validation measures against a peer certificate. This callback performs validation such as checking the certificate against a CRL and doing wildcard matching. The reason we need to define our own callback and validation code is because, as I understand it, the built-in OpenSSL wildcard matching will only process one wildcard field prefix (*.domain.com) whereas our requirements allow for wildcard patterns beyond just a prefix (FOO.*.domain.com, FOO.B*R.domain.com, etc.). The problem arises when I attempt to access 'ssl->tlsext_hostname' which is understood because this structure is now opaque. I believe the accessor function for this is '__owur const char *SSL_SESSION_get0_hostname(const SSL_SESSION *s);' in ssl.h. However, within the context of the callback function I only have two arguments to work with: int verify_callback(int ok, X509_STORE_CTX *ctx) This does not provide me with a SSL_SESSION object to pass into the SSL_SESSION_get0_hostname accessor function, so... 1. Is SSL_SESSION_get0_hostname() the right accessor for this data? 2. If so, how can I call SSL_SESSION_get0_hostname() within verify_callback() without a SSL_SESSION object? 3. Has the validation code for the 1.1 (and future) branches been changed so that I would no longer need to define my own validation code? (He asks hopefully) Thanks in advance for your help. -- Sent from: http://openssl.6102.n7.nabble.com/OpenSSL-User-f3.html
