Hi, Bernd! This assertion means that you are calling "GetRsa" method for a key which is not an RSA key. I am not sure why this happens. I don't believe that xmlSecOpenSSLKeyDataRsaGetEvp() can fail because it is just an access function to the underlaying openssl data structure.
If you get into debugger, it would be really nice to find out the value of pKey->type. Also I would suggest to check that openssl versions on this machine and the machine you've used to compile xmlsec match *exactly*. If this client machine has another copy of openssl and somehow xmlsec uses this another copy then all bets are off :) Aleksey _______________________________________________ xmlsec mailing list xmlsec@aleksey.com http://www.aleksey.com/mailman/listinfo/xmlsec
