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.

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.
