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 with the standard length and standard
characters.
func NewLen(length int) string
NewLen returns a new random string with the provided length and standard
characters.
func NewLenChars(length int, chars []byte) string
NewLenChars returns a new random string with the provided length and byte
slice of allowed characters (maximum 256).
