OpenSSL Crypto Poll Mode Driver
===============================
This code provides the initial implementation of the openssl poll mode
driver. All cryptography operations are using Openssl library crypto API.
Each algorithm uses EVP interface from openssl API - which is recommended
by Openssl maintainers.
For more details about openssl library please visit openssl webpage:
https://www.openssl.org/
Features
--------
OpenSSL PMD has support for:
Supported cipher algorithms:
* ``RTE_CRYPTO_CIPHER_3DES_CBC``
* ``RTE_CRYPTO_CIPHER_AES_CBC``
* ``RTE_CRYPTO_CIPHER_AES_CTR``
* ``RTE_CRYPTO_CIPHER_3DES_CTR``
* ``RTE_CRYPTO_CIPHER_DES_DOCSISBPI``
Supported authentication algorithms:
* ``RTE_CRYPTO_AUTH_AES_GMAC``
* ``RTE_CRYPTO_AUTH_MD5``
* ``RTE_CRYPTO_AUTH_SHA1``
* ``RTE_CRYPTO_AUTH_SHA224``
* ``RTE_CRYPTO_AUTH_SHA256``
* ``RTE_CRYPTO_AUTH_SHA384``
* ``RTE_CRYPTO_AUTH_SHA512``
* ``RTE_CRYPTO_AUTH_MD5_HMAC``
* ``RTE_CRYPTO_AUTH_SHA1_HMAC``
* ``RTE_CRYPTO_AUTH_SHA224_HMAC``
* ``RTE_CRYPTO_AUTH_SHA256_HMAC``
* ``RTE_CRYPTO_AUTH_SHA384_HMAC``
* ``RTE_CRYPTO_AUTH_SHA512_HMAC``
Supported AEAD algorithms:
* ``RTE_CRYPTO_AEAD_AES_GCM``
Installation
------------
To compile openssl PMD, it has to be enabled in the config/common_base file
and appropriate openssl packages have to be installed in the build environment.
The newest openssl library version is supported:
* 1.0.2h-fips 3 May 2016.
Older versions that were also verified:
* 1.0.1f 6 Jan 2014
* 1.0.1 14 Mar 2012
For Ubuntu 14.04 LTS these packages have to be installed in the build system:
sudo apt-get install openssl
sudo apt-get install libc6-dev-i386 (for i686-native-linuxapp-gcc target)
This code was also verified on Fedora 24.
This code was NOT yet verified on FreeBSD.
Initialization
--------------
User can use app/test application to check how to use this pmd and to verify
crypto processing.
Test name is cryptodev_openssl_autotest.
For performance test cryptodev_openssl_perftest can be used.
To verify real traffic l2fwd-crypto example can be used with this command:
.. code-block:: console
sudo ./build/l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_openssl"
--vdev "crypto_openssl"-- -p 0x3 --chain CIPHER_HASH
--cipher_op ENCRYPT --cipher_algo AES_CBC
--cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f
--iv 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:ff
--auth_op GENERATE --auth_algo SHA1_HMAC
--auth_key 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11
Limitations
-----------
* Maximum number of sessions is 2048.
* Chained mbufs are supported only for source mbuf (destination must be
contiguous).
* Hash only is not supported for GCM and GMAC.
* Cipher only is not supported for GCM and GMAC.
