New reads a nonce from a cryptographically secure random number source.

NewID returns a random 8 byte nonce to be used as identifiers.

IVLen is the length of Initialization Vectors used in Indra.

ID is a value generated by the first 8 bytes truncated from the values of a hash chain that reseeds from a CSPRNG at first use and every time it generates 2^16 (65536) new ID's.

IV is an Initialization Vector for AES-CTR encryption used in Indra.
