我想用 ECDH 生成一个 Curve25519 密钥对用于加密和解密。我正在使用 CryptoKit 生成密钥对。

但是，我未能使用 ECDH 算法生成密钥对。

迅速

func generateKeys() -> (publicKey: String, privateKey: String){
           let privateKey = Curve25519.KeyAgreement.PrivateKey()
           let publicKey = privateKey.publicKey
           let clientPublicKeyString = "-----BEGIN PUBLIC KEY-----\(publicKey.rawRepresentation.base64EncodedString())-----END PUBLIC KEY-----"
           print(clientPublicKeyString)
           let clientPrivateKeyString = "-----BEGIN PRIVATE KEY-----\(privateKey.rawRepresentation.base64EncodedString(options: .lineLength64Characters))-----END PRIVATE KEY-----\r\n"
           print(clientPrivateKeyString)
        return (clientPublicKeyString,clientPrivateKeyString)
    }

输出：

-----BEGIN PUBLIC KEY-----WSOOXYN/FaCOn4SAlvrW3q4IYueiS8Io+WqL64T2QQA=-----END PUBLIC KEY-----
-----BEGIN PRIVATE KEY-----AAlH4v1vcnmjEKVJrhbarMqCrcNWYZgFwnhReduEokk=-----END PRIVATE KEY-----

这是使用 bouncycastle 的 Java 代码之一

java代码的输出：

}

任何人都可以指导我吗？
