The parent comment is wondering about the structure of the signature and if different curve parameters can be specified for it. How can explicit curve parameters be specified in an ECDSA signature? ecdsaWithSHA256, at least, is simply two bigints. There's no spot for specifying explicit parameters.

This is answered upthread and in RFC 5480: the AlgorithmIdentifier has an ANY OPTIONAL field for parameters.
Missed that. Thank you!
