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.

58 Installation
59 ------------
60
61 To compile openssl PMD, it has to be enabled in the config/common_base file
62 and appropriate openssl packages have to be installed in the build environment.
63
64 The newest openssl library version is supported:
65
66 * 1.0.2h-fips  3 May 2016.
67
68 Older versions that were also verified:
69
70 * 1.0.1f 6 Jan 2014
71 * 1.0.1 14 Mar 2012
72
73 For Ubuntu 14.04 LTS these packages have to be installed in the build system:
74
75 .. code-block:: console
76
77     sudo apt-get install openssl
78     sudo apt-get install libc6-dev-i386 # for i686-native-linux-gcc target
79
80 This code was also verified on Fedora 24.
81 This code has NOT been verified on FreeBSD yet.
82
83 Initialization
84 --------------
85
86 User can use app/test application to check how to use this pmd and to verify
87 crypto processing.
88
89 Test name is cryptodev_openssl_autotest.
90 For asymmetric crypto operations testing, run cryptodev_openssl_asym_autotest.
91
92 To verify real traffic l2fwd-crypto example can be used with this command:
93
94 .. code-block:: console
95
96         sudo ./build/l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_openssl"
97         --vdev "crypto_openssl"-- -p 0x3 --chain CIPHER_HASH
98         --cipher_op ENCRYPT --cipher_algo AES_CBC
99         --cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
100         --iv 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:ff
101         --auth_op GENERATE --auth_algo SHA1_HMAC
102         --auth_key 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
103         :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
