   4 OpenSSL Crypto Poll Mode Driver
   5 ===============================
   6
   7 This code provides the initial implementation of the openssl poll mode
   8 driver. All cryptography operations are using Openssl library crypto API.
   9 Each algorithm uses EVP interface from openssl API - which is recommended
  10 by Openssl maintainers.

  50 Installation
  51 ------------
  52
  53 To compile openssl PMD, it has to be enabled in the config/common_base file
  54 and appropriate openssl packages have to be installed in the build environment.
  55
  56 The newest openssl library version is supported:
  57
  58 * 1.0.2h-fips  3 May 2016.
  59
  60 Older versions that were also verified:
  61
  62 * 1.0.1f 6 Jan 2014
  63 * 1.0.1 14 Mar 2012
  64
  65 For Ubuntu 14.04 LTS these packages have to be installed in the build system:
  66
  67 .. code-block:: console
  68
  69     sudo apt-get install openssl
  70     sudo apt-get install libc6-dev-i386 # for i686-native-linuxapp-gcc target
  71
  72 This code was also verified on Fedora 24.
  73 This code has NOT been verified on FreeBSD yet.
  74
  75 Initialization
  76 --------------
  77
  78 User can use app/test application to check how to use this pmd and to verify
  79 crypto processing.
  80
  81 Test name is cryptodev_openssl_autotest.
  82 For performance test cryptodev_openssl_perftest can be used.
  83
  84 To verify real traffic l2fwd-crypto example can be used with this command:
  85
  86 .. code-block:: console
  87
  88         sudo ./build/l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_openssl"
  89         --vdev "crypto_openssl"-- -p 0x3 --chain CIPHER_HASH
  90         --cipher_op ENCRYPT --cipher_algo AES_CBC
  91         --cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
  92         --iv 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:ff
  93         --auth_op GENERATE --auth_algo SHA1_HMAC
  94         --auth_key 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
  95         :11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
