[Openswan Users] IPSEC - Does `ping` involve any hashing activity?

[KokHow.Teh at infineon.com]

Hi;
	Greetings. I use openswan-2.4.9 to test my hardware
cryptographic drivers. Here is the /etc/ipsec.conf:

[root at Danube:~ 14]$ cat /etc/ipsec.conf
version 2.0
config setup
conn ifx
  left=10.10.10.1
  right=10.10.10.2
  ike=aes-md5
  esp=aes-md5
  authby=secret
  auto=add
[root at Danube:~ 15]$

	I configured the cryptographic hardware with AES and MD5
priorities to be at 400 and 300 respectively and put some debug messages
into the driver codes. While I could see the debug printouts of AES
encrypt/decrypt showing that AES is in operation and the hardware
cryptographic is used, I don't see any debug printout of hardware MD5 at
all. My question is if `ping` involve any hashing operation at all?
	Any insight is appreciated.

Regards,
KH
