Thanks! If you've come that far, MY_NID (which I assume is really NID_whatever) obviously exists, or your code wouldn't even have compiled. One possibility remains, that for some reason, libcrypto hasn't been initialised like it should. This can happen if you only call a very select set of OpenSSL functions. What happens if you add this at the start of your main()? OPENSSL_init_crypto(0, NULL); (note, that should be seen as a temporary measure, as this is called internally in quite a number of spots, so for larger uses of OpenSSL functionality, you shouldn't need that) Cheers, Richard -- Richard Levitte levitte@xxxxxxxxxxx OpenSSL Project http://www.openssl.org/~levitte/ -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
