What are you trying to achieve? Encryption at rest? Cryptographically signed splunk logs? Encryption at power off?</P> <P>Splunk can do cryptographically signed logs - <A href="http://www.splunk.com/base/Documentation/4.2.1/Admin/Signauditevents">http://www.splunk.com/base/Documentation/4.2.1/Admin/Signauditevents</A></P> <P>Crypto at power off can be handled using a crypto file system such as Luks - <A href="http://en.wikipedia.org/wiki/Linux_Unified_Key_Setup">http://en.wikipedia.org/wiki/Linux_Unified_Key_Setup</A></P> <P>Q2. I believe Splunk uses Zlib for compression.</P> Tue, 26 Apr 2011 13:05:51 GMT https://community.splunk.com/t5/Security/Encryption-and-compression-questions/m-p/88710#M2936 netwrkr 2011-04-26T13:05:51Z
