LoBC file format

List of blocked cryptographs (LoBC) is a sequence of uuids where each uuid relates to the blocked cryptograph.
Each UUID is encoded as two long (8 bytes long) in big-endian byte order.
For example the list with three ({FFEEE98C-25AD-4281-BC9A-9ED1E6CB0A55}, {35B21FDD-C8A7-430D-9B47-52A39411B182}, {77FFB311-A298-4696-8AB9-E3A7E2E97BA3}) UUIDs will look like:

FF EE E9 8C 25 AD 42 81 BC 9A 9E D1 E6 CB 0A 55
35 B2 1F DD C8 A7 43 0D 9B 47 52 A3 94 11 B1 82
77 FF B3 11 A2 98 46 96 8A B9 E3 A7 E2 E9 7B A3
