Overview

Command oid is a simple utility for generating un/ordered IDs.

By default, it is the base 32 encoding of a binary encoded string comprising an 8 byte nanosecond precision unix timestamp and an 8 byte random number, in that order. The timestamp prefix allows these IDs to be ordered.

Using '-uid' makes it a base 32 encoding of a binary encoded string comprising two 8 byte random numbers. These are not ordered

Usage: oid [option [option]...]

Options:

-h	display this message
-help
  	display this message
-hex
  	Use a standard HEX (a-f0-9) dictionary vs the default base32 (Crockford) dictionary.
-len int
  	The number of bytes of randomness to use. Keep in mind that UIDs use double this value for the overall length, while OIDs are this value +8 Bytes for the timestamp. (default 8)
-secure
  	Use a cryptographically secure randomness generator.
-uid
  	Generate an 'Unordered' ID (UID) vs the default 'Ordered' ID (OID).
