Add support for AES-192 in OpensslCipher. - Adds equivalent support for 192-bit AES/CTR/NoPadding codec in the OpensslCipher - Adds test-cases to cover 192-bit (24-bytes) and 256-bit (32-bytes) keys to both JCE and OpenSSL crypto tests - Enhances the error message when an invalid Key or IV size is passed into OpensslCipher You can merge this pull request into a Git repository by running: $ git pull https://github.com/QwertyManiac/hadoop HDFS-9878 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/hadoop/pull/135.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #135 commit 4e08bafaec31f0190f731f6ca0e07c7f2125d489 Author: Harsh J Date: 2016-10-06T05:52:22Z HDFS-9878.

[jira] [Commented] (HDFS-9878) Data transfer encryption with AES 192: Invalid key length.
[ https://issues.apache.org/jira/browse/HDFS-9878?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15173661#comment-15173661 ] Wei-Chiu Chuang commented on HDFS-9878: --- Good catch! [~karth295] thanks for reporting this issue. The native code for the cipher was implemented in HADOOP-10693 which does not support 192 bit encryption for OpenSSL from the beginning. After that, HDFS-6606 decided to add a property to make the encryption length configurable, and states that 192 bit is supported, despite the HADOOP-10693 implementation does not. Maybe this was intended for JCE? https://issues.apache.org/jira/browse/HDFS-6606?focusedCommentId=14125921&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14125921 However, looks like OpenSSL actually can support 192 bit. http://osxr.org:8080/openssl/source/crypto/evp/evp.h#0801 [~hitliuyi] would you comment on this? :) Thanks a lot. > Data transfer encryption with AES 192: Invalid key length. > -- > > Key: HDFS-9878 > URL: https://issues.apache.org/jira/browse/HDFS-9878 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode, hdfs-client >Affects Versions: 2.7.2 > Environment: OS: Ubuntu 14.04 > /hadoop-2.7.2/bin$ uname -a > Linux wkstn-kpalaniappan 3.13.0-79-generic #123-Ubuntu SMP Fri Feb 19 > 14:27:58 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux > /hadoop-2.7.2/bin$ java -version > java version "1.7.0_95" > OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-0ubuntu0.14.04.1) > OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode) > Hadoop version: 2.7.2 >Reporter: Karthik Palaniappan > > Configuring aes 128 or aes 256 encryption > (dfs.encrypt.data.transfer.cipher.key.bitlength = [128, 256]) works perfectly > fine.
