我嘗試使用 ed25519 身份驗證設置 SFTP 上傳，但不斷收到此錯誤：線程“main”中的異常 java.lang.UnsupportedOperationException：不知道如何解碼密鑰：ssh-ed25519這是我的代碼：import java.io.File;import java.io.IOException;import net.schmizz.sshj.SSHClient;import net.schmizz.sshj.sftp.SFTPClient;import net.schmizz.sshj.userauth.keyprovider.OpenSSHKeyFile;import net.schmizz.sshj.xfer.FileSystemFile;import net.schmizz.sshj.transport.verification.PromiscuousVerifier;String username     = "scansionitesz"; String remoteDir    = "files";String remoteFile   = "prova_delega.pdf";String localDir     = "C:/Users/VERSIM/Desktop";final SSHClient ssh = new SSHClient();ssh.addHostKeyVerifier(new PromiscuousVerifier());ssh.connect(server);try {    File privateKey = new File(openSSHPrivateKey);    KeyProvider keys = ssh.loadKeys(privateKey.getPath());    OpenSSHKeyFile key = new OpenSSHKeyFile();    key.init("-----BEGIN OPENSSH PRIVATE KEY-----\n" +             "my_private_key\n" +             "-----END OPENSSH PRIVATE KEY-----",            "ssh-ed25519 my_public_key scansionitesz@tes"             );    ssh.authPublickey(username,key);    final SFTPClient sftp = ssh.newSFTPClient();    try {        sftp.put(new FileSystemFile(localDir + "/" + remoteFile), "/" + remoteDir);    } finally {        sftp.close();    }} finally {    ssh.disconnect();}我缺少什么？
