PACKAGE

package uniuri
import "github.com/dchest/uniuri"

Package uniuri generates random strings good for use in URIs to identify
unique objects.

Example usage:

	s := uniuri.New() // s is now "apHCJBl7L1OmC57n"

A standard string created by New() is 16 bytes in length and consists of
Latin upper and lowercase letters, and numbers (from the set of 62 allowed
characters), which means that it has ~95 bits of entropy. To get more
entropy, you can use NewLen(UUIDLen), which returns 20-byte string, giving
~119 bits of entropy, or any other desired length.

Functions read from crypto/rand random source, and panic if they fail to
read from it.


CONSTANTS

const (
    // Standard length of uniuri string to achive ~95 bits of entropy.
    StdLen = 16
    // Length of uniurl string to achive ~119 bits of entropy, closest
    // to what can be losslessly converted to UUIDv4 (122 bits).
    UUIDLen = 20
)


VARIABLES

var StdChars = []byte("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890")

Standard characters allowed in uniuri string.


FUNCTIONS

func New() string

New returns a new random string of the standard length, consisting of
standard characters.

func NewLen(length int) string

NewLen returns a new random string of the provided length, consisting of
standard characters.

func NewLenChars(length int, chars []byte) string

NewLenChars returns a new random string of the provided length, consisting
of the provided byte slice of allowed characters (maximum 256).
