One asks if it is possible to use as hash algorithm a value of “null” in JunOS, as in the following command of ScreenOS:
set ike p2-proposal “g5-esp-aes256-no_auth-900s” group5 esp aes256 null second 900
The answer would be YES ! how ?
Setting NULL encryption means actually not setting any encryption-algorithm under IPsec proposals
[edit security ipsec]
NULL encryption algorithm is not supported in FIPS mode.
