SQL Server 2005: using symmetric keys to encrypt data. In SQL Server 2005, the recommended method for encrypting data is to use symmetric keys. A symmetric key can be created using the CREATE SYMMETRIC KEY statement. Information about symmetric keys is stored in the sys.symmetric_keys catalog.
From reading the IKE and IKEv2 RFC's, I know that both of them at some point generate KEYMAT, which is meant to be passed to IPsec so that IPsec can generate its own symmetric keys. IKEv1 generates KEYMAT using this formula: PFS Disabled: KEYMAT = prf(SKEYID_d, protocol | SPI | Ni_b | Nr_b).
