I've tried to make one and it points me about key bit length. Reading about this on http://en.wikipedia.org/wiki/Elliptic_Curve_DSA I also noticed that a timing attack is possible against OpenSSL. Quick checking the code shows that we haven't integrated the fix yet as current revision of http://svnweb.freebsd.org/base/stable/9/crypto/openssl/crypto/ecdsa/ecs_ossl.c?revision=225736&view=markup http://svnweb.freebsd.org/base/head/crypto/openssl/crypto/ecdsa/ecs_ossl.c?revision=225736&view=markup misses the fix from: http://cvs.openssl.org/chngview?cn=20892 And after latest OpenSSH import by des: http://svnweb.freebsd.org/base?view=revision&revision=221420 we are automatically creating (and using?) private ECDSA key: http://svnweb.freebsd.org/base/stable/9/etc/rc.d/sshd?r1=221419&r2=221420&; >How-To-Repeat: >Fix: Import fix from http://cvs.openssl.org/chngview?cn=20892 >Release-Note: >Audit-Trail: >Unformatted:
