 // The canonical form is displayed in 5 groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters.
 // The hexadecimal values "a" through "f" are output as lower case characters.

 // Note: for security reason, we should always generate version 4 UUID that use a scheme relying only on random numbers.
 // This algorithm sets the version number as well as two reserved bits. All other bits are set using a random or pseudorandom
 // data source. Version 4 UUIDs have the form xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx with hexadecimal digits for x and one of 8,
 // 9, A, or B for y.
