Reserved1 (2 bytes): This value MUST be ignored by the recipient and MUST be set to zero.
Reserved2 (2 bytes): This value MUST be ignored by the recipient and MUST be set to zero.
Reserved3 (4 bytes): This value MUST be ignored by the recipient and MUST be set to zero.
KeyType (4 bytes): Indicates the type of key, stored as a 32-bit unsigned integer in little-endian byte order. This MUST be set to one of the following values, which are defined in section 2.2.10.8.

KeyLength (4 bytes): The length, in bytes, of the value beginning at KeyOffset. The value of this field is stored in little-endian byte order.
KeyOffset (4 bytes): An offset, in little-endian byte order, from the beginning of the property value (that is, from the beginning of the Revision field of KERB_STORED_CREDENTIAL) to where the key value starts. The key value is the hash value specified according to the KeyType.
