Remarks
This implements NIST SP 800-108 HMAC in counter mode. The implemented KDF assumes the form of PRF (KI, [i]2 || Label || 0x00 || Context || [L]2)
where [i]2
and [L]2
are encoded as unsigned 32-bit integers, big endian.
All members of this class are thread safe. If the instance is disposed of while other threads are using the instance, those threads will either receive an ObjectDisposedException or produce a valid derived key.
