https://datatracker.ietf.org/doc/html/rfc5758#section-3.2 says this:
When the ecdsa-with-SHA224, ecdsa-with-SHA256, ecdsa-with-SHA384, or
ecdsa-with-SHA512 algorithm identifier appears in the algorithm field
as an AlgorithmIdentifier, the encoding MUST omit the parameters
field. That is, the AlgorithmIdentifier SHALL be a SEQUENCE of one
component, the OID ecdsa-with-SHA224, ecdsa-with-SHA256, ecdsa-with-
SHA384, or ecdsa-with-SHA512.
Otherwise, the certiticates generated by tools that conform this rule, cannot be verified, or der encodings add that parameter and chain verifications of the TBS certificate fail.
This pull request fixes this, by omitin the parameter for algid where the signature algorithm is one of the mentioned above.
