OpenSSL versions before 1.0.0 needed a cipherstring option to use ECC suites *in SSL/TLS protocol*, but local operations have worked as long as I remember. What version of OpenSSL are you running, and how was it built? In particular was it from official source, or patched? A couple of remote possibilities: do you have your openssl.cnf set (editted) to load an "engine", which doesn't support ECC? I didn't think this level of parsing goes to an engine, but I could be wrong. Do you have a FIPS-capable build and a setting to force FIPS mode? FIPS should allow ECC (it is NIST "Approved"), but something might be broken. Can you try the same file with a different OpenSSL version or build -- often easiest by using a different system? ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
