The format for an ECDSA or DSA signature is an ASN.1 SEQUENCE of two
Hi Matt,
Thanks very much!
I'm glad I'm on the right track in regards to EVP vs EC.

is the format of a signature? How do I find out?
Just to confirm - whether it's ECDSA or RSA, for verification, we just get
the EVP_PKEY
remember doing something along the lines of :
ecPublicKey = X509_get_pubkey(readCertificate);
EC_KEY *ecKey;
ecKey = EVP_PKEY_get1_EC_KEY(ecPublicKey);
EC_KEY_set_asn1_flag(ecKey, Put in the curve name);
ecGroup = EC_GROUP_new_by_curve_name(Put in the curve name);
EC_KEY_set_group(ecKey,
