I am generating Symmetric-keys by using bouncy castle Diffie-Hellman key exchange protocol, but when I display my generated Secret then it gives me the following error
我通过使用充气城堡Diffie-Hellman密钥交换协议生成对称密钥，但是当我显示我生成的秘密时它会给我以下错误
java.lang.IllegalStateException: Key agreement has not been completed yet
java.lang.IllegalStateException：密钥协议尚未完成
Assume from the below code that keys agreement process has be successfully completed and also from the hashes it confirms that both keys are the similar.
从下面的代码中假设密钥协商过程已经成功完成，并且从散列中确认两个密钥都是相似的。
MessageDigest hash = MessageDigest.getInstance("SHA1");
byte[] aShared = hash.digest(aKeyAgree.generateSecret());
byte[] bShared = hash.digest(bKeyAgree.generateSecret());
System.out.println(Arrays.toString(aKeyAgree.generateSecret()));

It's probably simply that calling aKeyAgree.generateSecret() twice is the issue. The key agreement should be performed just once. If you want to print the result you need to store it in a (temporary) variable instead.
可能只是两次调用aKeyAgree.generateSecret（）是个问题。密钥协议应该只执行一次。如果要打印结果，则需要将其存储在（临时）变量中。
