java - BouncyCasSTLe 编码差异

Question

我正在尝试计算公钥的哈希值以匹配 ApplePay 提供给我的内容。我无法让 C# 中的 BouncyCaSTLe 为我提供正确格式的公钥，以便我可以对它进行哈希处理。然而，我正在移植的 Java 版本工作得很好。 OpenSSL 也给出了正确的响应，但我不希望必须与 OpenSSL 以及 BC 打交道才能做到这一点。

Java:(有效)

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:(有效)

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

C#:(keyBytes 错误)

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
AAAAAAAAAAAAD///////////////8wWwQg/////wAAAAEAAAAAAAAAAAAAAAD/

移植 GetEncoding 的正确方法是什么？

我知道关键数据是错误的，因为当我从 openssl 手动强制输入数据时，我得到了正确的哈希值。

编辑:添加输出。

Answer 1

我认为这只是:

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