Vol 3 (Host), Part H (SM): 3 (SMP), 3.6.1 Key distribution and generation

Opcode::IDENTITY_INFORMATION

[uint8_t opcode]
jau::uint128_t identity_resolving_key

Message is used in the Transport Specific Key Distribution phase to distribute Identity Resolving Key (IRK).

The message shall only be sent when the link has been encrypted or re-encrypted using the generated key.

Legacy: #3 in distribution
Secure Connection: #1 in distribution, first value.

Notable: No endian wise conversion shall occur on this data, since the encryption values are interpreted as little-endian or as a byte stream.
