-----------------------------------------------------------
[~lindongdong] you can check the previous CI results, if we define an unused method, CI will be unhappy. and I still don't know why there is a compatible issue, the method you said will not be used any place, can you please explain more ?
@[~zZtai] can you please answer the reason of modification of OpensslSecureRandom.c for lindongdong?

> SM4 (formerly SMS4)is a block cipher used in the Chinese National Standard for Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure).
> SM4 was a cipher proposed to for the IEEE 802.11i standard, but has so far been rejected by ISO. One of the reasons for the rejection has been opposition to the WAPI fast-track proposal by the IEEE. please see:

> *Use sm4 on hdfs as follows:*
> 1.Configure Hadoop KMS
> 2.test HDFS sm4
> hadoop key create key1 -cipher 'SM4/CTR/NoPadding'
> hdfs dfs -mkdir /benchmarks
> hdfs crypto -createZone -keyName key1 -path /benchmarks
> *requires:*
> 1.openssl version >=1.1.1
