Functions

func GenUUID

func GenUUID(size int, timezone ...string) string

GenUUID generates a Unique Identifier using a custom build method

Notice: This feature is currently in beta

@size: (minimum: 8) the bit size for the last part of the uuid (note: other parts may vary)

@timezone: optionally add a timezone string to the uuid (note: you could also pass random info into here for a more complex algorithm)

This method uses the following data:

• A hash of the current year and day of year
• A hash of the current timezone
• A hash of the current unix time (in seconds)
• A hash of the current unix time in nanoseconds and a random number

The returned value is url encoded and will look something like this: xxxx-xxxx-xxxx-xxxxxxxx

func RandBytes

func RandBytes(size int, exclude ...[]byte) []byte

RandBytes generates random bytes using crypto/rand

@exclude[0] allows you can to pass an optional []byte to ensure that set of chars will not be included in the output string

@exclude[1] provides a replacement string to put in place of the unwanted chars

@exclude[2:] is currently ignored
