ipsec auto --status shows :

algorithm ESP encrypt: id=7, name=ESP_BLOWFISH, ivlen=64, keysizemin=96, 
algorithm ESP encrypt: id=252, name=ESP_SERPENT, ivlen=128, 
keysizemin=128, keysizemax=256
algorithm ESP encrypt: id=253, name=ESP_TWOFISH, ivlen=128, 
keysizemin=128, keysizemax=256

ESP algorithms wanted: TWOFISH(253)_000-MD5(1), BLOWFISH(7)_000-MD5(1), 
SERPENT(252)_000-MD5(1); flags=strict

So what will be the keylength used?
