编码差异

我正试图计算公钥的哈希值以匹配ApplePay给我的内容。我无法让c#中的BouncyCastle以正确的格式给我公钥，以便我可以散列它。然而，我移植的Java版本工作得很好。OpenSSL也给出了正确的响应，但我不希望为了做到这一点而不得不处理OpenSSL和BC。

Java(作品):

ECPublicKey key = (ECPublicKey) certificate.getPublicKey();
byte[] keyBytes = key.getEncoded(); 
MessageDigest messageDigest = MessageDigest.getInstance("SHA256", PROVIDER_NAME);
byte[] keyHash = messageDigest.digest(keyBytes);    
String base64keyBytes = new String(Base64.encode(keyBytes));
//base64keyBytes == MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAE+4wQWWRnPqGlsncZX17t0CfLOl6u
// 68aXUsqnzlIcpCdDukHhxibd2MjHPFGpnK3ZKdHxIFh+NBQvGssM5ncm1g==
// line break added for readability

OpenSSL(作品):

openssl x509 -noout -pubkey -in <file> -inform der 
-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAE+4wQWWRnPqGlsncZX17t0CfLOl6u
68aXUsqnzlIcpCdDukHhxibd2MjHPFGpnK3ZKdHxIFh+NBQvGssM5ncm1g==
-----END PUBLIC KEY-----

c#: (keyBytes是错误的)

SubjectPublicKeyInfo pubinfo = SubjectPublicKeyInfoFactory.CreateSubjectPublicKeyInfo(certificate.GetPublicKey());
byte[] keyBytes = pubinfo.GetEncoded();
byte[] keyHash = DigestUtilities.CalculateDigest("SHA_256", keyBytes);
string keyBytesEncoded = Convert.ToBase64String(keyBytes);
/*keyBytesEncoded == MIIBKjCB4wYHKoZIzj0CATCB1wIBATAsBgcqhkjOPQEBAiEA/////wAAAAEAAA

移植GetEncoding的正确方法是什么?

我知道这是关键数据错误，因为当我手动从openssl强制数据时，我得到了正确的哈希值。

编辑:添加输出

编码差异

我想应该是:

byte[] keyBytes = certificate.CertificateStructure.SubjectPublicKeyInfo.GetDerEncoded()
