Thank you, Emanuele. We really need to use the FIPS version of OpenSSL, so updating the code isn't a possiblity.
However, looking into the source it looks as though all of the functions that we need are there, so hopefully we can get the functionality we require by writing a bit of code ourselves which links to the FIPS library.

ECDSA has also doxygen comments :-) bye! -- Emanuele Cesena <emanuele.ces...@gmail.com> http://ecesena.dyndns.org Il corpo non ha ideali ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org Please help Logica to respect the environment by not printing this email / Merci d'aider Logica à préserver l'environnement en évitant d'imprimer ce mail / Bitte drucken Sie diese Nachricht nicht aus und helfen Sie so Logica dabei die Umwelt zu schuetzen / Por favor ajude a Logica a respeitar o ambiente não imprimindo este correio electrónico.
