我創(chuàng)建了一個(gè) RSA 密鑰對(duì)?，F(xiàn)在，我正在嘗試使用 DES 算法加密私鑰，將其格式化為 PKCS#5 并將其打印在控制臺(tái)上。不幸的是，生成的私鑰不起作用。當(dāng)我嘗試使用它時(shí)，輸入正確的密碼后，ssh 客戶端返回密碼無(wú)效：加載密鑰“test.key”：用于解密私鑰的密碼不正確可以請(qǐng)有人告訴我我錯(cuò)在哪里嗎？這是代碼：private byte[] iv;public void generate() throws Exception {    RSAKeyPairGenerator generator = new RSAKeyPairGenerator();    generator.initialize(2048);    KeyPair keyPair = generator.generateKeyPair();    String passphrase = "passphrase";    byte[] encryptedData = encrypt(keyPair.getPrivate().getEncoded(), passphrase);    System.out.println(getPrivateKeyPem(Base64.encodeBase64String(encryptedData)));}private byte[] encrypt(byte[] data, String passphrase) throws Exception {    String algorithm = "PBEWithMD5AndDES";    salt = new byte[8];    int iterations = 1024;    // Create a key from the supplied passphrase.    KeySpec ks = new PBEKeySpec(passphrase.toCharArray());    SecretKeyFactory skf = SecretKeyFactory.getInstance(algorithm);    SecretKey key = skf.generateSecret(ks);    // Create the salt from eight bytes of the digest of P || M.    MessageDigest md = MessageDigest.getInstance("MD5");    md.update(passphrase.getBytes());    md.update(data);    byte[] digest = md.digest();    System.arraycopy(digest, 0, salt, 0, 8);    AlgorithmParameterSpec aps = new PBEParameterSpec(salt, iterations);    Cipher cipher = Cipher.getInstance(AlgorithmID.pbeWithSHAAnd3_KeyTripleDES_CBC.getJcaStandardName());    cipher.init(Cipher.ENCRYPT_MODE, key, aps);    iv = cipher.getIV();    byte[] output = cipher.doFinal(data);    ByteArrayOutputStream out = new ByteArrayOutputStream();    out.write(salt);    out.write(output);    out.close();    return out.toByteArray();}
