> 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:
> [https://en.wikipedia.org/wiki/SM4_(cipher)]
>
> *Use sm4 on hdfs as follows:*
> 1.download Bouncy Castle Crypto APIs from bouncycastle.org
> [https://bouncycastle.org/download/bcprov-ext-jdk15on-165.jar]
> 2.Configure JDK
> Place bcprov-ext-jdk15on-165.jar in $JAVA_HOME/jre/lib/ext directory,
> add "security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider"
> to $JAVA_HOME/jre/lib/security/java.security file
> 3.Configure Hadoop KMS
> 4.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
> 2.configure Bouncy Castle Crypto on JDK
