It looks like in OpenSSL 1.1.0 I can no longer do that. There are only functions available that return various function pointers from a X509_STORE_CTX structure (like X509_STORE_CTX_get_cert_crl), but there are no corresponding counterparts to set the function pointers. This could be viewed as a bug; we had no idea people wanted to *set* various fields. WE consider missing accessors/setters in opaque datatypes a bug. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
