Hello
I would like to sign the digest of a file using the elliptic curve
sect233r1
I generate my by
openssl ecparam -genkey -name sect233r1 -noout -out id_eckey
Signing by
openssl dgst -sha1 -sign id_eckey file => OK => OK
openssl dgst -sha512 -sign id_eckey file => NOK
When I try to generate de digest before
It works with an rsa key but not with ecdsa key
openssl dgst -sha1 -out dg1 Makefile
openssl pkeyutl -sign -inkey id_rsa -in dg1 => OK
openssl pkeyutl -sign -inkey id_eckey -in dg1 => NOK
Could you tell me where I'm wrong.
Thanks
Regards
Bruno
