Rfc4122\Version

enum Ramsey\Uuid\Rfc4122\Version → int

The version number describes how the UUID was generated.

case Time → 1

A version 1 UUID uses a timestamp based on the Gregorian calendar epoch, along with the MAC address (or node) for a network interface on the local machine. For more details, see Version 1: Gregorian Time.

case DceSecurity → 2

Like a version 1 UUID, a version 2 UUID uses the current time, along with the MAC address (or node) for a network interface on the local machine. Additionally, a version 2 UUID replaces the low part of the time field with a local identifier such as the user ID or group ID of the local account that created the UUID. For more details, see Version 2: DCE Security.

case HashMd5 → 3

Name-based UUIDs combine a namespace with a name. This way, the UUIDs are unique to the namespace they’re created in. Version 3 UUIDs use the MD5 hashing algorithm to combine the namespace and name. For more details, see Version 3: Name-based (MD5).

case Random → 4

Version 4 UUIDs are randomly-generated identifiers. For more details, see Version 4: Random.

case HashSha1 → 5

Name-based UUIDs combine a namespace with a name. This way, the UUIDs are unique to the namespace they’re created in. Version 5 UUIDs use the SHA-1 hashing algorithm to combine the namespace and name. For more details, see Version 5: Name-based (SHA-1).

case ReorderedTime → 6

case UnixTime → 7

case Custom → 8
