Hallo, I try to verify an ECDSA signature, which is by definition
given as the concatenation of 2 octet-streams (BIGNUM r and BIGNUM
s), the base64 encoded version is:
"449afHAqHfJZmkET0a0hYVpaj+n1bbe4eTmHRAQsA+Zsl/px3AWzb5fWGjRzWWtz"
(This is part of an xmldsig-ecdsa document, exatly the
"SignatureValue" entry.)
I don't know how to convert the octet-streams to the "DER"
representation, which would help me to create an ECDSA_SIG structure
by passing it to the d2i_ECDSA_SIG.
Does there exist any converstion tools or maybe you can give me a
hint how to do it myself, i really have no idea at the moment.
Thank you very much in advance.
