How much faster is AES-NI?

How much faster is AES-NI?

AES-NI is up to 10 times faster than AES on the ARM processor.

Does OpenSSL use AES-NI?

So that conclusion is that AES-NI is used by default for openssl.

How do I enable AES-NI in Linux?

Enabling or disabling processor AES-NI support

  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Processor AES-NI Support and press Enter.
  2. Enabled—Enables AES-NI support. Disabled—Disables AES-NI support.

How do you check if AES-NI is enabled Windows?

Visit the following Intel website and look up the processor model to see if it supports AES-NI: http://ark.intel.com/search/advanced/?AESTech=true. Download CPU-Z application and run it on the client. This will display the CPU capabilities: http://www.cpuid.com/softwares/cpu-z.html. Install DE.

How to check if OpenSSL is using AES-NI?

To test if openssl is using AES-NI I found following information. You can’t see after compiling that AES-NI is available for openssl, but you can perform performance tests with and without that feature. The result the first line will run faster (almost double on my i7 cpu). So that conclusion is that AES-NI is used by default for openssl.

How big is the performance gap between AES and AES-NI?

After 1024 bytes, the speed is nearly the same, so we suggest to use the 8192 bytes as a unit to encrypt in the PostgreSQL.At the same time, we can know that AES-NI will have up to 10 times the performance gap between opening and closing.

How to get the performance of the AES modes?

There is much Standard encryption algorithm in OpenSSL. We will use OpenSSL to test the AES modes performance. How to get the performance resultsYou can refer to the official document: https://www.openssl.org/docs/manmaster/man1/speed.html. Here we will use the following command to do the performance test.

How to get the performance results of OpenSSL?

How to get the performance resultsYou can refer to the official document: https://www.openssl.org/docs/manmaster/man1/speed.html. Here we will use the following command to do the performance test. The tests for each input data size was performed for 3 seconds, for the ciphers that we were interested in.
