Hi ,
I run the below two command and generated the private key for ecdsa sign . But i thinks its not the correct lenght that why my signature creation is failing. 1.openssl ecparam -out ec_key.pem -name secp224r1 -genkey 2. openssl req -newkey ec:ec_key.pem -x509 -nodes -days 365 -keyout ecdsapriv.pem -out ecdsapublic.x509 cat ecdsapriv.pem -----BEGIN PRIVATE KEY----- MHgCAQAwEAYHKoZIzj0CAQYFK4EEACEEYTBfAgEBBBz5PninGQKcwsfBzSdQwL8Z sofs53EyzZPLWvzHoTwDOgAEipOs1lPyOKrz4D/WGLdh6yE0WhewJIPxoDP1Rf0V 6D2I5SBwV8Bv28zpitRviKIJTp8st1j9iGg= -----END PRIVATE KEY----- can anybody guide me which the private key here I am use for signing the data. Private ekey lenght should be 28 bytes for secp224r1 this curve.
