+# VPP IPSec implementation using DPDK Cryptodev API {#dpdk_crypto_ipsec_doc}
+
+This document is meant to contain all related information about implementation and usability.
+
+
+## VPP IPsec with DPDK Cryptodev
+
+DPDK Cryptodev is an asynchronous crypto API that supports both Hardware and Software implementations (for more details refer to [DPDK Cryptography Device Library documentation](http://dpdk.org/doc/guides/prog_guide/cryptodev_lib.html)).
+
+When DPDK Cryptodev support is enabled, the node graph is modified by adding and replacing some of the nodes.
+
+The following nodes are replaced:
+* esp-encrypt -> dpdk-esp-encrypt
+* esp-decrypt -> dpdk-esp-decrypt
+
+The following nodes are added:
+* dpdk-crypto-input : polling input node, basically dequeuing from crypto devices.
+* dpdk-esp-encrypt-post : internal node.
+* dpdk-esp-decrypt-post : internal node.
+
+
+### How to enable VPP IPSec with DPDK Cryptodev support
+
+To enable DPDK Cryptodev support (disabled by default), we need the following env option:
+
+ vpp_uses_dpdk_cryptodev=yes
+
+A couple of ways to achive this:
+* uncomment/add it in the platforms config (ie. build-data/platforms/vpp.mk)
+* set the option when building vpp (ie. make vpp_uses_dpdk_cryptodev=yes build-release)
+
+
+### Crypto Resources allocation
+
+VPP allocates crypto resources based on a best effort approach:
+* first allocate Hardware crypto resources, then Software.
+* if there are not enough crypto resources for all workers, all packets will be dropped if they reach ESP encrypt/decrypt nodes, displaying the warning:
+
+ 0: dpdk_ipsec_init: not enough cryptodevs for ipsec
+
+
+### Configuration example
+
+No especial IPsec configuration is required.
+
+Once DPDK Cryptodev is enabled, the user just needs to provide cryptodevs in the startup.conf.
+
+Example startup.conf:
+
+```
+dpdk {
+ socket-mem 1024,1024
+ num-mbufs 131072
+ dev 0000:81:00.0
+ dev 0000:81:00.1
+ dev 0000:85:01.0
+ dev 0000:85:01.1
+ vdev cryptodev_aesni_mb_pmd,socket_id=1
+ vdev cryptodev_aesni_mb_pmd,socket_id=1
+}
+```
+
+In the above configuration:
+* 0000:85:01.0 and 0000:85:01.1 are crypto BDFs and they require the same driver binding as DPDK Ethernet devices but they do not support any extra configuration options.
+* Two AESNI-MB Software Cryptodev PMDs are created in NUMA node 1.
+
+For further details refer to [DPDK Crypto Device Driver documentation](http://dpdk.org/doc/guides/cryptodevs/index.html)
+
+### Operational data
+
+The following CLI command displays the Cryptodev/Worker mapping:
+
+ show crypto device mapping [verbose]
