Resolution: Duplicate
> Add SM4 encryption method for HDFS
> ----------------------------------
>
> Key: HDFS-15284
> URL: https://issues.apache.org/jira/browse/HDFS-15284
> Project: Hadoop HDFS
> Issue Type: New Feature

> please see:
> https://en.wikipedia.org/wiki/SM4_(cipher)
> *patch to hadoop trunk branch*
> 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
