Im getting the following error using openssl x509 -inform DER -in cms_cert.der -text 140026491385512:error:100D7010:elliptic curve routines:ECKEY_PUB_DECODE:EC lib:ec_ameth.c:206: 140026491385512:error:0B07707D:x509 certificate routines:X509_PUBKEY_get:public key decode error:x_pubkey.c:164: I found a message stating that: "Your public key parameter field is set to NULL. It must either be an OID to name the curve, or explicit parameters." Does this apply to the pkey i have attached to this message too ? Windows does not complain about the key tho. Is the key RFC conform (its not mine, but i have to validate it) ? Thanks
