  由于JDK版本不同，在Java 8 update 161版本以后就会出现此问题，根本原因还是DH密钥长度至少为512位，而DES算法密钥没有这么长，密钥长度不一致引起的。

  解决方法：

  配置JVM的系统变量：-Djdk.crypto.KeyAgreement.legacyKDF=true

  我的也是，怎么解决的 啊！

  java.security.NoSuchAlgorithmException: Unsupported secret key algorithm: DES

  at com.sun.crypto.provider.DHKeyAgreement.engineGenerateSecret(DHKeyAgreement.java:387)

  at javax.crypto.KeyAgreement.generateSecret(KeyAgreement.java:648)

  at com.wbs.security.dh.ImoocDH.jdkDH(ImoocDH.java:50)

  at com.wbs.security.dh.ImoocDH.main(ImoocDH.java:24)

  
  

  47        KeyAgreement receiverKeyAgreement = KeyAgreement.getInstance("DH");

  48        receiverKeyAgreement.init(receiverPrivateKey);

  49        receiverKeyAgreement.doPhase(receiverPublicKey, true);

  50        SecretKey receiverDesKey = receiverKeyAgreement.generateSecret("DES");

  这里的 DES。

  //3.密钥构建

  KeyAgreement receiveKeyAgreement = KeyAgreement.getInstance("DH");

  receiveKeyAgreement.init(receivePrivateKey);

  receiveKeyAgreement.doPhase(receivePublicKey, true);

  SecretKey receiveDesKey = receiveKeyAgreement.generateSecret("DES");
