Erlang UUID Implementation

http://www.ietf.org/rfc/rfc4122.txt is the reference for official UUIDs. This implementation provides a version 1 UUID that includes both the Erlang pid identifier (ID, Serial, Creation) and the distributed Erlang node name within the 48 bit node ID. To make room for the Erlang pid identifier, the 48 bits from the MAC address (i.e., 3 OCI (Organizationally Unique Identifier) bytes and 3 NIC (Network Interface Controller) specific bytes) and the distributed Erlang node name are bitwise-XORed down to 16 bits. The Erlang pid is bitwise-XORed from 72 bits down to 32 bits. The version 3 (MD5), version 4 (random), and version 5 (SHA) methods are provided as specified within the RFC.

Requires Erlang >= R14B01
