The reason I am asking is because setkey in ablkcipher and blkcipher check key length for min and max size. Thus for example, aes, when using a 256 bit key, would pass in 288 bits or 36 octet key. max is 32 bits, so would result in error. If not passed into setkey, then I assume the salt/nonce would be parsed from key when ipsec daemon passes keys into kernel...
