2.2.5.16 Phase 2 - Suite Keys

Each authentication set could contain a list of suites which express cryptographic proposals that will be negotiated. These suites can be stored in Software\Policies\Microsoft\WindowsFirewall\Phase2CryptoSets\<wszSetId>\<SuiteIndex> where the SuiteIndex is a 4 digit decimal value encoded as a string.

The suite keys represent the pPhase2Suites array field of the FW_CRYPTO_SET structure as defined in [MS-FASP] section 2.2.73.

The suites for phase 2 cryptographic sets differ from those of phase 1 authentication sets. The following sections describe how these phase 2 cryptographic suites are encoded. The semantic checks described in [MS-FASP] section 2.2.70 are also applicable to the cryptographic phase 2 suites described in this section after following the mapping of the registry values and tokens.
